🔥Amazon’s BEST Deals (updated daily): amzn.to/4aaLjCO ☑Check out my sponsor to begin your FREE 14 day trial to Aura: aura.com/chrismaher In this video I will do a complete walkthrough of the 3 most common ways to power LED Strips as well as how to inject power into your longer led runs. I am definitely not an expert when it comes to powering led strips but the goal of this video is to hopefully show you that its not as hard or complex as you might think. In all my projects where I have powered things the way shown in the video, I generally have the maximum current on the WLED limiter set anywhere from 850 mA - 2000 mA which has always been bright enough to achieve the desired results. I also don't leave my led lights on overnight and will generally be in the room when they are turned on. Even though I have never had any issues, make sure to consult a trained professional if you are worried about safety.

Hey Chris, I am trying to make a parts list for everything I would need to power 4 5m 60 2812BECO light strips. So far I have the strips, 18 gauge wire, ESP32 Development boards, 2 of the 60 amp power supply's and the necessary 3 wire power cables, and Wago connectors. Is it necessary to have the 20 gauge extension wire or can the power injection be done with the 18 gauge? Did I leave anything else out? Thanks
Love the video, but I do have some serious concerns about the methods you explain...... now I don't want to be mean or degrading so please take this as constructive criticism, nothing else meant with it, we're all here to learn! I'm also fully open to discussion or questions, etc! Overall assumed values: 300LEDs of ws2812b when properly injected can use up to 13Amps (65w) real-world, I've done extensive power measurements and publish a real-world power sheet for lots of types of LEDs to know what to expect and calculate with. For general usage I normally use the 50% white value which would be 6,5Amps or 32,5w to run single colors and effects at 100% brightness. A single injection point cannot take in more then ~4Amps before voltage drop becomes too high and it basically won't do much anymore. If you want to power a 300LED strip of ws2812b for 100% RGB white you will need proper sized wires and front + middle + end injections, anything less then that and they won't be running at their full potential. So in all scenarios shown you where running limited. Although that can be fine, this will also in part limit smoothness and such. Each LED has a Red, Green and Blue diode which have 256 steps of brightness. Limiting them also limits the range they can use and thus will things more "choppy". Basically 50% power means it now only has 128 steps, not 256. Now the WLED limiter is good and doesn't do this per LED but overall and in real-time, but still, using 850mA will for sure show this for instance. Setup 1 - 2000mA phone charger A. Make sure to test this charger can deliver a sustained 2000mA and won't overheat B. The ESP board (circuit traces) and USB socket are not rated for anything close to 2000mA C. The included USB cable probably already has quite a bit of resistance and will start to drop voltage over 1000mA D. Dupont wires, please please don't use over 500mA on these Running addressable LEDs like this can be done, but please don't exceed 850mA, even that is stressing it already in my opinion. Now this can be fine in some situations where you don't have a lot of LEDs or don't mind running them at low brightness, still, it can be dangerous (fire!) running more power through this setup, the hardware is NOT designed for it (dupont really shouldn't exceed 500mA). Most likely the resistance on the USB cable is already lowering voltage coming into the ESP board (and with it Amps) and then the dupont wires will lower it even more, but still. This is not the correct way to run any decent amount of LEDs... Setup 2 - 5v 10Amp power supply Already much better! But still I have issues.... A. Those barrel plug adapters, please please don't use them for 5v, it's stupid they come with them, they are not to be used over 3Amps continuous or will melt. But just snip off the barrel plug on the PSU wire and use those wires directly. :) B. 18AWG wire is nice, but since you are only using it to power the ESP using dupont wires here would have been fine actually. :) But as said, this setup is much better but won't draw more then 4Amps to maybe 5Amps before voltage drop becomes too much of an issue again. Still that can be fine for running single colors and some effects. It would however be better to use a 6 or 7.5Amp power supply since then if it has OCP that could provide a little bit of protection against shorts or other issues. A fuse here might be a good idea but the PSU not being giant also gives a bit of protection already (f it's good quality). Setup 3 - 5v 60Amp power supply Better but also somewhat worse. When using such big power supplies their internal protection mechanisms will not work for you anymore so you need to add protection yourself in the form of a fuse per injection line, etc. A. Fuses! B. Using a 20AWG 5m/16ft wire for 5v really doesn't work. In what you showed with front + end, it will equalize voltage a little bit, but really doesn't do enough. Voltage drop calculator says 16ft/5m of 20AWG doing 4Amps will have 1.3v of drop just on the wire alone which then becomes heat.... C. Adding the second strip make this problem worse since it's now not an edge connection but a middle injection capable of delivering up to ~8Amps into the strip effectively but as shown in the video, it already has 2.6v drop on just the wire alone. Now because it's 5v and the resistance makes the voltage drop it probably won't burn up, but it's not a good situation either as is kind of shown by the result in the video too. So basically, all scenarios are seriously under powering the LEDs, this is also why at some point you won't see a difference when moving the sliders around in WLED for instance. This can be ok if that's a choice, but still. All scenarios also only work because you are attaching the very short wires on the LED strip directly to the power source, using the same type of wires even just a little bit longer will make all of the scenarios fail basically. Now you mention in the video you aren't an expert in this and learning yourself, that's good! I kind of partly then think maybe not make "advice" videos like this on the subject but I also get you need to start somewhere. Maybe next time do a bit more analysis of your setups, include voltage measurements using a multi-meter at the start and end of the wire when set to a single color or 100% RGB white, do the same at the start middle and end of the strip, etc.. That would make it a bit more scientific and you'll start figuring out more why some of the stuff you are seeing is happening and what is a good situation and what isn't and can potentially be dangerous. :)
Thanks so much for taking the time to respond with such great information! I'm all about learning and it sounds like you would be a great person to learn from! Do you do this for fun or is it part of your career? Thanks for all the advice and for watching! Also, i'm a huge fan of your work. What video of yours goes into this type of detail? I'd love to link it in the description of my video so people can watch.
Thank you for this very detailed technical answer and carring about our safety. Can you please let us know what is the best simple power supply and wires to Buy for powering a WS2812B led strip of 5 meter and 2 x 5 meter with 300 to 600 leds. Thank you
@@MrTubertub The reason why you will probably not find a video that clearly states the wire sizes and power supplies is because they will all end up with the same answer "It depends". Every setup is unique in regards of lengths and power requirements, some use more or less lights, straight wires instead of moving around obstacles, those kinds of things.. There are some resources that explain each step more in detail, but I do not want to hijack this video to promote others. The most important steps are explained here, keeping those in mind should improve the safety of any installation you create. The very dirty short answer would be to first calculate (roughly) the maximum amount of power your strip will need. As Quindor stated that would be about 65W for WS2818b strip with 100% RGB white. with the recommendation to calculate mostly for 50% RGB white, that then translates in to about 33W for a 5 meter strip (1 roll of 60 LED/m or 16,4ft) and to 65W for a 10 meter strip (2 rolls of 60LED/m or about 33ft). Now that you know the power, you can base the rest of the calculations on those numbers. First of all, the power supply. Generally best practice is to have a PSU can can supply more power than the maximum you want from it. Good rule of thumb would be to have about 10-15% more power than required. Following that rule you'd look at buying a PSU capable of doing about 40W for a single strip, and about 75W for 2 strips. That's the easy part. Moving on to the wires themselves.. Since power always tries to balance things out in a perfect world, you can start looking at the number of injection points you require to transfer all those amps to the LED's safely. For the 65W example, that would be (65W divided by 5V) 13A. Knowing that a front/end injection can transfer about 4A in to the strip, and a middle injection about 8A, this would be possible by injecting power in the front (start of the first strip), middle (between the 2 strips) and end (end of the second strip). If you'd go to for example full brightness, you'd require 26A (or 130W). In that case you will need to inject front (4A), middle of the first strip (8A), middle of the 2 strips (8A), middle of the second strip (8A) and end of the second strip (4A). Than you will be able to get (4+8+8+8+4) 32A max in to the strip, with room to spare on the 26A the strip will take. For each of these injection points you can then calculate the wire size required to safely transfer the power over the distance. Start here by measuring the distance from the power supply (or even better a fuse box) to the LED strip and note all those distances. Then pair that distance with the expected maximum power on that wire. We'll take the example of the 5m long injection wire. So that wire would be 5m long, carry 5V 8A, and needs to stay within 10% voltage drop. The 10% voltage drop is the standard tolerance of most electric equipment, unless specified otherwise. You can use a voltage drop calculator for that, and that will tell you, you would need a 12AWG wire to transfer that power, with about 8.8% voltage drop. Now I know for many people this will seem crazy and they won't believe you need such a large wire for this.. But the truth is, if you want to transfer low voltage over a large distance with a few amps, the wire almost needs to be perfect to not drop more than 10% voltage. Higher voltages have a better tolerance since there is more room to play with. For example 5V 10% is only 0.5V while if you use 12V 10%, that's already 1,2V tolerance. Go to mains voltage and the drop allowed is even bigger in terms of voltage. Hope this helps!
Heyyyy thankyou for such an in detail review I don't even knw wht videos u upload on ur channel but jst this review and inisder u gave I subed ur channel, thnx for giving such in detail info about this topic I would really love to check out ur channel and actually as a beginner in RGB stop lightning u actually cleared my confusion should I go for 12v or 5v one after you, I m cleared out tht I'm going for the 12v ws2811 strip thankyou so much for this ❤ mahn !! Keep up the grt work
Fantastic info. Thank you for sharing. I subscribed to your channel and joined your discord server. A question for you and OP @ChrisMaherDIY, are these MeanWell power units noisy? Do they require further housing?
It's great that you mention not just how much power these led strips use, but that not all the power can make it from one end to the other. A while back, I put up a bunch of warm white led strips and noticed that one side of the room was brighter than the other. Voltage drop from one end to the other was enormous.
Yeah it would be nice if voltage drop did not happen lol. It would make working with LED lights so much easier! Thanks for watching and taking the time to comment!
This is exactly what I was imagining I’d have to do. I’ve got a 48” run and plan on going 90% brightness with these same LEDs from Amazon. I don’t want to run any cables down the wall, so I plan on starting it from a closet. I’ll have to run 4 pairs of wires down to the third strip to have 0 degradation of power. You’re the only person I see who actually explains and demonstrates it all step by step thank you so much!
what a great tutorial and very different from others I have seen. Your practical approach and using the limiter to help maintain colors is great. This has shown me that there are many solutions beyond injecting power every X amount of pixels. Thank you and keep them coming.
You are very welcome! Glad the video was helpful! I know when I first started 1 year ago I had no idea what I was doing (and still dont most of the time lol) but i'm slowly learning things as I go! Let me know if you ever have any questions!
@@ChrisMaherDIY not sure if you have done so but it would be really helpful to have a video about how to tie in the WLED lights with alexa or siri or something and how to set the custom lights up for home automation. Maybe you ought make a tutorial for this as well?
Great walk through. This is the only video I've seen that clearly shows an injection wire running all the way from the power source, along side the LED strip to the far end. Thanks for clearing that up! 13:09 - There's an obvious color change for both the un-injected and single injected wiring for the two parallel LED strips. 14:25 - *I* see very little color change when only the beginning and middle injection points are enabled. Shouldn't this look exactly like 13:09?
Thanks so much for watching and I'm glad you liked the video. I went back and watched the sections and you are right. My only guess as to what the difference might have been at the 14:25 point was even though I know I had the limiter turned off, I might have fogot to turn the brightness all the way up on the WLED brightness slider and therefore it was not as obvious as a difference. Good catch!
Just an FYI, you could look into 6 amp "mini-amplifiers" instead of that bulky one with the protruding pins you use, the "mini-amplifiers" are no bigger than a usb flash drive but half as thick, so much easier to hide when you hang your lights, and they do the same function, keeping the remote controls in-sync and are a buck or 2. They also help with injection just being wired into the sequence
Thanks so much for the great suggestion! I've never heard of mini amplifies so I'm very intrigued! Hiding big stuff is sometimes a nightmare so anything to help on that front would be amazing! Thanks so much!
@@ChrisMaherDIY Hey Chris, I was wondering, will the animations only work with "Govee" light strips or is it the control unit that drives the animations?. My lights are good quality, but only have the cheesy remote that has like 12 colors and just a few animations (fade, flash etc)
Well done. Exactly what we all need to know and were wondering about. Thank you. I'm impressed by how well the phone charger works. So much cheaper than the big boy option and we all have those chargers lying around.
Thanks so much for watching! That's a bummer! Yeah with these type of leds you need to have more than just the led strips. In the description I do leave links to everything that I used in the video including the led strips, power supply options, esp devices and wires. Hope that helps!
Ok so I gave this a go .. and how fun is this! I'm gonna invite my mates over with their sons so we can have a LED workshop and make some lights for church. Thanks again :)
Dude this is the best walk thru for this type of thing that i have every since thanks so much for sharing this info. This was exactly what ive been needing to know.
Hey Chris, I STAND CORRECTED! Although my mini-amp idea does work keeping 3 strands in-sequence, your wifi board is vastly, ridiculously BETTER for it's functionality, and is so worth it's larger size. You can easily hide the wifi board by simply using longer wires and having it end in anyplace you wish. If you're lighting a bedroom for example, the obvious place is a closet, you'll want to do this with the 60 amp supply unit for sure as it's the size of cigar box. PAY ATTENTION TO CHRIS, I've watched dozens of videos and tried many configurations, power supplies and Chris's video is the only one that is both accurate and user-friendly
Thanks so much for the follow up! I'm certainly no expert so I'm always looking for better/different ways to do things so i'm always glad when people bring up new ideas! But I'm glad that the way I did it seems to be working for you! I appreciate all the kind words my friend! Hope you have a great day!
Pretty sweet, I'm going to start messing with this stuff. I ordered some lights and a controller from your links below. Hopefully over time I can make something nice for my room. I appreciate the time you take to create these videos. I really like your content. Subbed.
Thanks so much! Its a fun hobby for sure and the most fun part is coming up with something in your mind and then trying to make it. I'm still very new myself but if you have any questions along the way I always try to respond to every comment or question.Thanks for the sub!
Hey Chris, you’re a life savior my men I follow another tutorial video and got stuck thankfully your video pop up I was using the D2 pin instead of D4 I really thought I had return all 7 rolls 16ft strip. Thank you brother!!! God bless you!
Thanks so much for watching! yeah the longer i've been doing this the more I realize there are a lot of different ways to go about doing something. I've recently started using Wago connectors for things like this and they are amazing. If you are just trying to connect 2 wires together, these in line ones work great: amzn.to/3XrpXdS
Great videos and great work. As someone who watches tons of DIY YT videos I always skip and X2 the playback in order to sum up the videos. The style you have in delivering your information as well your video cuts and side bar walk-through leave me immersed and following along at normal speed. Great job keep up the great work. Very inspirational 👏 🙌
Thanks Chris! Ill use your videos as cuide for my first led addressable project. I was planning to conect 8 10m strips on a big roof. And now I think I will make it. Thanks to your videos, I will start with 1 line and see how it works 💓
Thanks so much for watching and glad you liked the video! For any really big projects like that I always recommend people watching this video from Dr. Zzz. Really good stuff. He is a lot smarter than I am: ruclips.net/video/S0g02o85fGY/видео.html
Well done! Very good demo! I am gathering a few things to build my diy wled strip and I was wondering about the power supply, wether I should get a more powerful than my 5V/2A usb charger. Your video cleared a lot the things up. Kudos!
Great! I just bought 4 - 5 meter strips , a 60A 300w ps and you proved that I'm going to have to run alot of injection wire to get even white from pixel 1 to pixel 1200.
Thanks so much for watching! I always just test things and start off with no power injection and then go from there based on how things look! Good luck and hope everything turns out great!
@@ChrisMaherDIY Thanks with that thought. I have set up the whole 1200 LEDs in the garage in a test situation while I am mounting the tracks on the roofline so that is ready once I get the power figured out to a bare minimum of wires, injection points etc. PS really love the lighting ideas you bring forward in your vids.
@@graphguy thanks so much! What a fun project your doing! Feel free to send me a video when you have it set up! I'd love to see how it turned out! My email is in my RUclips info
@@ChrisMaherDIY ok . I'm a tad confused. I have 1500 (60/m) 5v leds up in 5 strips. I have power at the start and I added one home run at the very end and that is it. Every single WLED effect works just fine and looks great! So how come every person says that in that situation I would many injections?
@@graphguy You are confused just like I was and still am to some extent. So when people ask how much power will they need, there is the theoretical amount you will need if you wish to run the lights at full brightness and on white, and then there is the power (much less power required) that is needed if you are only planning on running animations and colors. Thats why I generally say, it will depend on what you are wanting to do with the lights. As you have noticed, you dont need a lot of power to run most animations and if things look good and your happy, then your done! But my guess (and I could be wrong) but if you turn the lights to white and at full brightness, you might see some color/voltage drop and would maybe do some more injection. Hope that makes sense!
I used an old surface tablet adapter with usb and rated at 5v 2.5A. It was perfect for powering my small controller and about 3 strands of 50 bullet nodes. Once I plugged in 2 more strands I saw some drop off but when my sequence hit the all white segement, anything beyond the 2nd strand turned pinkish orange instead of white. These are a great way to see where your drop off will happen. I have purchased a 350w 70A big boy power supply to wire up my tree with (and a few other models) I'm here to confirm my understanding of wiring the injection points and you confirmed I understood it correctly. Red to VCC+ and white to VCC-
Exactly what I was looking for! In my case I'll need about 13 Meter long led strip and I was pretty sure I wouldn't get away with connecting from one side only, but as I never ever touched any led strips had to make sure and I still got time in the home project! Thank you!
This is VERY USEFUL. It shows how to properly power long strips of LEDs, instead of just powering from one end, then wondering why the strip or matrix burned out! The wires connecting them together aren't heavy enough to conduct all that amperage through, so you have to "inject" more power through the leads provided. Great video! Hopefully this will help some of the no-brain Gen-Zers out there, trying to get though life without EVER learning anything except what they call "hacks" that allow then to meander along without ever becoming knowledgeable about anything. Heaven forbid they might accidentally learn something. And, this was appropriately titled, for a change. You could've just titled this "Comparison of Power Supplies and Methods of Powering LED strips." That way, it's easier to find in s search. I hate it when ppl mis-title their videos, just to get lots of views. YT should encourage PROPER TITLING, instead of encouraging MIS-titling the way they do now! It just makes sense. After awhile, there's trillions of videos online, but nobody knows what any of them are about without having to watch each one until you find what you're looking for. That's just crap, and a massive waste of time. But, hey, does YT care?! Of course not. They just want VIEWS.
I wish RUclips had more videos like yours. Clear even for dumdum like me, straight to the point but with explanations and practical example for vicarious experimenting. I've had the stupid idea of making one of those "old-telephone lamp" but with an rgb led strip inside, instead of the bulb coming out from the handset. Using an esp32 (that just came today after weeks, and I've never used a microcontroller nor led strip nor made a lamp out of this stuff. So this videos are fresh air for my noob brains. Thanks
Great video! I would like to add something to this. You used 5m 5V 60 led/m strip. 1 meter consumes 18W at full brightness. That means that you will need 3,6A for full white. With 5m it will be 90W and at least 18A power supplier will be requaired. 1A=1W / 1V 1W=1A * 1V 1V=1A / 1W easy math ;) It also recommended to have addicional 10% of power in your project. Just for LEDs. With 5V power supply You can power up your other 5V devices such as HDMI splitters, raspberry pi's and so on.
Thanks so much for watching! I have not tested out that length yet but my guess is there would be minimal noticeable drop in voltage. I could be wrong but that's my guess! If I ever test out things with that length, I'll let you know!
Question: I always thought the extra 2 wires off the led strips (the unused ones) were for power injection. If so, couldn't you use them for power and then just plug data and ground from the esp to the plug?
You are 100% correct. You could certainly use the extra 2 wires at the begining to feed the power/gnd since they are soldered to the exact same pad that the ones I used were connected too. I never know how detailed to go in someo of these videos but thats something I could have definitly clarified. Thanks for watching buddy!
Yeah I have some of mine setup like this. Power supply connects to the power injection wires and then I use the JST connector to connect to the ESP8266 for power, ground, and data
Thanks for the video! I’m following the 3rd method and after wiring everything up and plugging it in it would appear the power supply isn’t getting power. If I power the ESP board via USB both the ESP & power supply have LEDs turn on, but nothing is happening when plugging in via the power supply. Any suggestions? EDIT: I had to switch the power supply to 110v. All good now!
You just need to install WLED onto the 8266 board before you will be able to control the lights. Here is a video I made going over how to do that. ruclips.net/video/l8OMi7SMpqs/видео.html
Question, the data wire does not have to be connected to additional strips? I can not get any info anywhere about the DATA wire, so as long as its connected once to the strip I can inject power anywhere and be good? so no need to connect the yellow or sometimes green data wire to the rest of the strips?
Thanks a ton, this was really helpful for a house exterior lighting project I'm doing. 22 meters of 30 led/meter to illuminate a white house with seasonal colours.
Are you running this with more than 1 Node MCU? I was wanting to do similar, wasnt sure how many strips could be run from one NodeMCU, and was not sure if I was going to need 2 60 amp power supplies as well. I havent seen a video of 3-4 strips hooked together.
@@mattglandorf9600 FWIW, I initially picked up a 60A psu because I did the math incorrectly. A 10A would have worked but it turns out a 60A was cheaper so I stuck with it. How many LEDs are you trying to power?
Thanks for watching! Thats a good question! I have yet to try maxing things out but I think you would probably reach the limit of WLED before reaching the power limit if I had to guess. That would however be a fun thing to test out! Here is what WLED say about max number of leds on the esp32 device (esp32 is a little more powerful than the esp8266) ESP32 There is a maximum of 10 strips supported Contrary to the ESP8266, the pin usage does not matter on ESP32, feel free to use any available pin For perfect performance, it is recommeded to use 512 LEDs/pin with 4 outputs for a total of 2048 LEDs. For very good performance, it is recommended to use 800 LEDs/pin with 4 outputs for a total of 3200 LEDs. For good performance, you can use 1000 LEDs/pin with 4 outputs for a total of 4000 LEDs. For okay performance, you can use 1000 LEDs/pin with 5 outputs for a total of 5000 LEDs. For okay performance, you can use 800 LEDs/pin with 6 outputs for a total of 4800 LEDs. ESP32 can calculate about 65k-85k LEDs per second (that means 1000 LEDs @~70fps, 2000 LEDs @~35fps, 4000 LEDs @~18fps) 4 outputs seem to be the sweet spot.
i have a dumb question. If i have enough power, can i power up 2x (ESP32 + Led) with only 1 power supply ? so 1 x power supply (5v 10a) -> 2 x ESP 32 with 1m led
@@ChrisMaherDIY awesome thank you! Want to get all my ducks in a row before I pull the trigger on $300 to get some sound reactive LEDs in my game room. Your channel has been paramount in helping me learn what I need to. I appreciate your efforts and your reply!
Instead of using Wago connectors and twisting wires to connect them, can We solder the wires together for a less costly option? Also the 3 Pin LED Extension Wire 20 AWG,for WS2812B be used as normal wire for other projects such as connecting wires to a a esp board for example? Appreciate your tests and info!
Hi chris. Bit of a problem here. I’ve connected my esp32 board with wled installed. I’ve connected the jumper cables from the board to a 5v, 5 metre consisting of 60 LEDs per metre. I connected a micro usb like you did on the esp board. The light on the board stays on aswell as the last led on the roll without any others working and when connected to the wled no luck with any of the strip working except the last led. I’ve got the ground on the right pin, I know I need more power injection but I’m just trying to test out the setup to see if it works before I connect the power. In your video a 5v Samsung charger seems to work. Any help recommended please. The direction of the LEDs are connected right aswell.
Thanks so much for watching! It for sure can be done. I have still not done anything that big but it is for sure on my to do list for videos. I know WLED has a certain limit that they recommend when it comes to LEDS kno.wled.ge/features/multi-strip/ But when I do get around to doing a big install like this, I'll for sure make a video of it and then hopefully i'll know a little but more on how to go about setting something up like this!
I think it all depends on personal preference. Now there is certainly a limit of leds that will work with a phone charger (not 100% sure what that limit is) but the lower the brightness you have the leds set to the more leds will be able to work and look accurate. I would just do some trial and error. Start with 50 leds and play around with the brightness and see what you think. If it looks good, add more leds and keep testing. Thanks for watching!
Thanks so much for watching! I've never added fuses to any of the projects I've done. And even though I have never had any issues at all, its still probably a good idea to do. I have not made any videos on this process but it is something I do want to make a video on in the future.
does this apply to 12v led strips? i thought i you had to cut the positive from the strip before adding power injection because you cannot have two positives? or maybe i misunderstood. is this right?
Thanks so much for watching! This is only for 5v but a lot of what's shown here is very similar on 12v strips. I made a video going over a little bit of a 12v setup: ruclips.net/video/zbhdH-qSANc/видео.html
Just to make sure that i am fully understanding here, you are putting power to both ends of each led strip? I am in the process of putting these strips around our bonus room. Is there a wiring diagram that i can see?
How would you mount that power supply unit so it isn't sitting on its shell? Having a hard time figuring out the search terms to differentiate these power sources from PC power supplies, etc.
That's a good question! I'm also not too familiar with pc power supplies so I'm afraid I'm not much of a help on this topic. Maybe someone else reading might know and can chime in!
No you should not need another module as long as the two led strips are connected by the data wire. If you are not going to connect the first led strip to the second with the same data flow, then you would use another module for the second led strip.
Ok so I am running a molding style strip in my sons room where the wall meets the ceiling. Using the 30 mill corner channels. I think will be using strips with 30 led’s RGB no white per meter and it is a 44’ linear run around the perimeter of the room. If the four corners of the room are A B C D and I have my power supply and esp32 start at corner A. can I run all the way around and inject power at the end when it gets back to corner A? Also what power supply would you guys suggest? Tips and suggestions appreciated this is my first LED project
Thanks so much for watching and great question! I still have not done any large projects like your mentioning but If I were doing this I would first test things out on the floor and probably start with a 5v 30a power supply (assuming your using 5v led strips) and have power at the beginning and then at the end, turn things on and see how things look and go from there. Being that your using led strips that have 30 leds per meter, my guess is most animations would look just fine like that but would probably see some voltage drop in the middle if you are trying to run them at full brightness and power. But I'm certainly no expert so I would also love to hear what others would do!
Thanks so much for watching! Here is a video I did on a 12v led strip that has the backup data pin: ruclips.net/video/zbhdH-qSANc/видео.html I think most people either just add the backup data to the gnd or add it to the regular data. I'm not sure what is best but I would try one of those two options!
Do i still need to power the board with the usb cable, or will it just take power from the dc adapter through the vin and gnd pins connected to the female dc?
Thanks for watching! You can definitely power the board with the dc adapter. I think I go over the way I do it in this video: ruclips.net/video/TOEnFKLm9Sw/видео.html
Thanks so much for watching and that's a great question. I think it would be very different just based on the lights that cob strips have vs the individually addressable strips. I think wherever you buy them would have the specific power requirements of that particular strip.
That should be perfect for 3 led strips! Probably need 1 or 2 injection points of power depending on how bright / if you want them to be all white. But if you are mostly wanting them to be displaying different colored animations, you could probably get away with just 1 injection spot.
I have setup like setup #1 with a USB power Supply with microUSB powering the LEDs and ESP8266 board. The boards constantly fail. I have gone through 3 already and am not sure what is causing it. It is around 140 LEDS and 5v3amp power. I notice in WLED it says "Keep at
Thanks for watching! Yeah I would keep the limiter turned on and try setting it at 1000mha if you're going through boards like that. See if that makes a difference!
Setup 2 you should be good. I think the issue comes from too much through the micro USB on the board. Setup 2 doesn't have anything plugged into the micro USB. I've only ever fried a board when I accidentally connected the esp32 to a 12v power supply!
Im a total novice to this but very intrigued. Does the power injection need to be added at the end of each strip or can it be daisy chained to the next strip then back to the power supply at the end of the run?
Great question! You can add power wherever you want. So you can daisy chain 2 strips together and if necessary, add power to the end of the second led strip. I will always test things out with no power injection and see how everything looks and then go from there. I'll inject power if necessary. Let say you connect 5 long strip together and inject power at the end to go along with the power at the beginning. My guess is that the LED's in the middle of those 5 strips will be a different color since the power is not getting to them with as much as they need so you would more than likely need to inject power at around the middle point so that those leds will have enough juice. Hope that helps!
Thanks for watching and taking the time to comment! I've never built anything that big but the power supply I linked to in the video (the big one) is about as big as they come. The led lights can only take so much power and there will always be voltage drop that unfortunately wont be able to be avoided by simply using a bigger supply. The best advice is to wire everything up and see how it looks at different levels of brightness. It may work for what you need it to at a lower brightness with power injection only at the end but my guess is you will need to somehow figure out a way to inject power at different points with that many leds.
Do injection points need to be soldered onto the strip itself, or if I have extension wires connecting multiple strips I can insert it into the middle of a string of wires?
You can do some mixing and matching as long as they were the same type of strip and same voltage requirements. The extra white and red wires are there in case you want to inject power into the led strip you can just connect the injection wires to those! Thanks for watching!
That's a great question and I'm not entirely sure on the answer. I've never used a stepdown converter for any of my projects and I've never had any issues with the chips getting fried. However, I've also read where you should use a stepdown converter. So I don't have a clear yes or no answer other than it probably is a good idea to use one even though I have not and have not so far had any problems.
Hey man, I know it's a bit of an older video but i was trying to get your opinion on something. I want to run those EXACT same LED strips along the top of my room through diffuser channels, and i was planning on using the big power supply and power injection run through the channels. The main issue for me is the fact i'm using 3 5 meter strips (60led/meter) in total to wrap around my whole room. I am unsure if this power supply can fully power all 3 strips connected together, and if the controller would be able to be used for the whole thing? Would I need more than one controller? Thanks!
For some reason after i plug the live and neutral my -v and +v does not have any power. And the led on the source is green . What can cause that? I can’t test the led strip as there’s no power coming out on +v
I could really use some help. I have Two WS2812B . I connect the connectors and can’t get the 2nd light to come on. Are you saying I can inject power from the red and white wires (the ones I’m not using) from either end? Why doesn’t any power carry through the 3 wire connector? Why do I have to use the red/white ?
quick question to connect 20 meters of strip ( 5 meters sets x4 ) do you recommend 12v or 24v? i will like an option i can use a single power supply to power all 20 meters from the beginning - i assume at the end of each strip i will connect the data cable to the data cable of the other strip ? also a single controller can run all 20 meters correct .. thank you so much for all your time and videos.
Thanks so much for watching! I'm not quite sure if this is accurate but I think you can assign the lights to turn on with a certain animation. I'm not sure about turning off with a animation in reverse though. Maybe someone else reading the comments might know for sure? I'm also not sure if there is a different controller out there that can do this.
Hey Chris. Do you know if this will work when the phone is offline again?... trigger in app and log off... or does it need a constant signal from the app?
Thanks so much for watching and great question! So when I have the lights on and lets say my phone turns off. The lights will just continue to do what they are doing.
I've learned SO much from your videos!! I purchased this power supply to run 3 strips of WS 2812B (900 LED's). I have power running to the first led strip, and another power injection connected to end of the 900 LED's. It works great, exactly what I needed. My question though is do I need to put a fuse on both positive wires coming from this power supply?
Can the 3rd led power unit be hardwired in. It looks like it to me as you can just skip the plug and wire it in the junction box in a wall. Also, can multiple strips be wired in one unit?
What about if you want to add two 5V sensors, let's say for the top floor of the house and the lower floor (so the sensors enable and/or disable the lights); would you still be able to connect both sensors with the second option (10Amps) with one 300 led strips and your led controller, or would it require a bigger power supply?

In this video I will do a complete walkthrough of the 3 most common ways to power LED Strips as well as how to inject power into your longer led runs. I am definitely not an expert when it comes to powering led strips but the goal of this video is to hopefully show you that its not as hard or complex as you might think. In all my projects where I have powered things the way shown in the video, I generally have the maximum current on the WLED limiter set anywhere from 850 mA - 2000 mA which has always been bright enough to achieve the desired results. I also don't leave my led lights on overnight and will generally be in the room when they are turned on. Even though I have never had any issues, make sure to consult a trained professional if you are worried about safety.

Hey Chris, I am trying to make a parts list for everything I would need to power 4 5m 60 2812BECO light strips. So far I have the strips, 18 gauge wire, ESP32 Development boards, 2 of the 60 amp power supply's and the necessary 3 wire power cables, and Wago connectors. Is it necessary to have the 20 gauge extension wire or can the power injection be done with the 18 gauge? Did I leave anything else out? Thanks
Love the video, but I do have some serious concerns about the methods you explain...... now I don't want to be mean or degrading so please take this as constructive criticism, nothing else meant with it, we're all here to learn! I'm also fully open to discussion or questions, etc!
Overall assumed values:
300LEDs of ws2812b when properly injected can use up to 13Amps (65w) real-world, I've done extensive power measurements and publish a real-world power sheet for lots of types of LEDs to know what to expect and calculate with. For general usage I normally use the 50% white value which would be 6,5Amps or 32,5w to run single colors and effects at 100% brightness.
A single injection point cannot take in more then ~4Amps before voltage drop becomes too high and it basically won't do much anymore. If you want to power a 300LED strip of ws2812b for 100% RGB white you will need proper sized wires and front + middle + end injections, anything less then that and they won't be running at their full potential.
So in all scenarios shown you where running limited. Although that can be fine, this will also in part limit smoothness and such. Each LED has a Red, Green and Blue diode which have 256 steps of brightness. Limiting them also limits the range they can use and thus will things more "choppy". Basically 50% power means it now only has 128 steps, not 256. Now the WLED limiter is good and doesn't do this per LED but overall and in real-time, but still, using 850mA will for sure show this for instance.
Setup 1 - 2000mA phone charger
A. Make sure to test this charger can deliver a sustained 2000mA and won't overheat
B. The ESP board (circuit traces) and USB socket are not rated for anything close to 2000mA
C. The included USB cable probably already has quite a bit of resistance and will start to drop voltage over 1000mA
D. Dupont wires, please please don't use over 500mA on these
Running addressable LEDs like this can be done, but please don't exceed 850mA, even that is stressing it already in my opinion. Now this can be fine in some situations where you don't have a lot of LEDs or don't mind running them at low brightness, still, it can be dangerous (fire!) running more power through this setup, the hardware is NOT designed for it (dupont really shouldn't exceed 500mA). Most likely the resistance on the USB cable is already lowering voltage coming into the ESP board (and with it Amps) and then the dupont wires will lower it even more, but still. This is not the correct way to run any decent amount of LEDs...
Setup 2 - 5v 10Amp power supply
Already much better! But still I have issues....
A. Those barrel plug adapters, please please don't use them for 5v, it's stupid they come with them, they are not to be used over 3Amps continuous or will melt. But just snip off the barrel plug on the PSU wire and use those wires directly. :)
B. 18AWG wire is nice, but since you are only using it to power the ESP using dupont wires here would have been fine actually. :)
But as said, this setup is much better but won't draw more then 4Amps to maybe 5Amps before voltage drop becomes too much of an issue again. Still that can be fine for running single colors and some effects. It would however be better to use a 6 or 7.5Amp power supply since then if it has OCP that could provide a little bit of protection against shorts or other issues. A fuse here might be a good idea but the PSU not being giant also gives a bit of protection already (f it's good quality).
Setup 3 - 5v 60Amp power supply
Better but also somewhat worse. When using such big power supplies their internal protection mechanisms will not work for you anymore so you need to add protection yourself in the form of a fuse per injection line, etc.
A. Fuses!
B. Using a 20AWG 5m/16ft wire for 5v really doesn't work. In what you showed with front + end, it will equalize voltage a little bit, but really doesn't do enough. Voltage drop calculator says 16ft/5m of 20AWG doing 4Amps will have 1.3v of drop just on the wire alone which then becomes heat....
C. Adding the second strip make this problem worse since it's now not an edge connection but a middle injection capable of delivering up to ~8Amps into the strip effectively but as shown in the video, it already has 2.6v drop on just the wire alone. Now because it's 5v and the resistance makes the voltage drop it probably won't burn up, but it's not a good situation either as is kind of shown by the result in the video too.
So basically, all scenarios are seriously under powering the LEDs, this is also why at some point you won't see a difference when moving the sliders around in WLED for instance. This can be ok if that's a choice, but still. All scenarios also only work because you are attaching the very short wires on the LED strip directly to the power source, using the same type of wires even just a little bit longer will make all of the scenarios fail basically.
Now you mention in the video you aren't an expert in this and learning yourself, that's good! I kind of partly then think maybe not make "advice" videos like this on the subject but I also get you need to start somewhere. Maybe next time do a bit more analysis of your setups, include voltage measurements using a multi-meter at the start and end of the wire when set to a single color or 100% RGB white, do the same at the start middle and end of the strip, etc.. That would make it a bit more scientific and you'll start figuring out more why some of the stuff you are seeing is happening and what is a good situation and what isn't and can potentially be dangerous. :)
Thanks so much for taking the time to respond with such great information! I'm all about learning and it sounds like you would be a great person to learn from! Do you do this for fun or is it part of your career? Thanks for all the advice and for watching! Also, i'm a huge fan of your work. What video of yours goes into this type of detail? I'd love to link it in the description of my video so people can watch.
Thank you for this very detailed technical answer and carring about our safety.
Can you please let us know what is the best simple power supply and wires to Buy for powering a WS2812B led strip of 5 meter and 2 x 5 meter with 300 to 600 leds.
Thank you
@@MrTubertub The reason why you will probably not find a video that clearly states the wire sizes and power supplies is because they will all end up with the same answer "It depends". Every setup is unique in regards of lengths and power requirements, some use more or less lights, straight wires instead of moving around obstacles, those kinds of things..
There are some resources that explain each step more in detail, but I do not want to hijack this video to promote others. The most important steps are explained here, keeping those in mind should improve the safety of any installation you create.
The very dirty short answer would be to first calculate (roughly) the maximum amount of power your strip will need. As Quindor stated that would be about 65W for WS2818b strip with 100% RGB white. with the recommendation to calculate mostly for 50% RGB white, that then translates in to about 33W for a 5 meter strip (1 roll of 60 LED/m or 16,4ft) and to 65W for a 10 meter strip (2 rolls of 60LED/m or about 33ft).
Now that you know the power, you can base the rest of the calculations on those numbers. First of all, the power supply. Generally best practice is to have a PSU can can supply more power than the maximum you want from it. Good rule of thumb would be to have about 10-15% more power than required. Following that rule you'd look at buying a PSU capable of doing about 40W for a single strip, and about 75W for 2 strips.
That's the easy part. Moving on to the wires themselves.. Since power always tries to balance things out in a perfect world, you can start looking at the number of injection points you require to transfer all those amps to the LED's safely. For the 65W example, that would be (65W divided by 5V) 13A. Knowing that a front/end injection can transfer about 4A in to the strip, and a middle injection about 8A, this would be possible by injecting power in the front (start of the first strip), middle (between the 2 strips) and end (end of the second strip). If you'd go to for example full brightness, you'd require 26A (or 130W). In that case you will need to inject front (4A), middle of the first strip (8A), middle of the 2 strips (8A), middle of the second strip (8A) and end of the second strip (4A). Than you will be able to get (4+8+8+8+4) 32A max in to the strip, with room to spare on the 26A the strip will take.
For each of these injection points you can then calculate the wire size required to safely transfer the power over the distance.
Start here by measuring the distance from the power supply (or even better a fuse box) to the LED strip and note all those distances. Then pair that distance with the expected maximum power on that wire. We'll take the example of the 5m long injection wire. So that wire would be 5m long, carry 5V 8A, and needs to stay within 10% voltage drop. The 10% voltage drop is the standard tolerance of most electric equipment, unless specified otherwise. You can use a voltage drop calculator for that, and that will tell you, you would need a 12AWG wire to transfer that power, with about 8.8% voltage drop.
Now I know for many people this will seem crazy and they won't believe you need such a large wire for this.. But the truth is, if you want to transfer low voltage over a large distance with a few amps, the wire almost needs to be perfect to not drop more than 10% voltage. Higher voltages have a better tolerance since there is more room to play with. For example 5V 10% is only 0.5V while if you use 12V 10%, that's already 1,2V tolerance. Go to mains voltage and the drop allowed is even bigger in terms of voltage.
Hope this helps!
Heyyyy thankyou for such an in detail review I don't even knw wht videos u upload on ur channel but jst this review and inisder u gave I subed ur channel, thnx for giving such in detail info about this topic I would really love to check out ur channel and actually as a beginner in RGB stop lightning u actually cleared my confusion should I go for 12v or 5v one after you, I m cleared out tht I'm going for the 12v ws2811 strip thankyou so much for this ❤ mahn !! Keep up the grt work
Fantastic info. Thank you for sharing. I subscribed to your channel and joined your discord server.
A question for you and OP @ChrisMaherDIY, are these MeanWell power units noisy? Do they require further housing?
It's great that you mention not just how much power these led strips use, but that not all the power can make it from one end to the other. A while back, I put up a bunch of warm white led strips and noticed that one side of the room was brighter than the other. Voltage drop from one end to the other was enormous.
Yeah it would be nice if voltage drop did not happen lol. It would make working with LED lights so much easier! Thanks for watching and taking the time to comment!
This is exactly what I was imagining I’d have to do. I’ve got a 48” run and plan on going 90% brightness with these same LEDs from Amazon. I don’t want to run any cables down the wall, so I plan on starting it from a closet. I’ll have to run 4 pairs of wires down to the third strip to have 0 degradation of power.
You’re the only person I see who actually explains and demonstrates it all step by step thank you so much!
That sounds like a great project! Thanks so much for watching and taking the time to comment and I'm glad you liked the video!
what a great tutorial and very different from others I have seen. Your practical approach and using the limiter to help maintain colors is great. This has shown me that there are many solutions beyond injecting power every X amount of pixels. Thank you and keep them coming.
Thanks again buddy!! Glad you liked the video! Appreciate the support my friend!
Thank you for the tutorial! I‘m new to diy led stuff but want to make kinda advanced stuff in my room… this video helped me perfectly!
You are very welcome! Glad the video was helpful! I know when I first started 1 year ago I had no idea what I was doing (and still dont most of the time lol) but i'm slowly learning things as I go! Let me know if you ever have any questions!
@@ChrisMaherDIY not sure if you have done so but it would be really helpful to have a video about how to tie in the WLED lights with alexa or siri or something and how to set the custom lights up for home automation. Maybe you ought make a tutorial for this as well?
Great walk through. This is the only video I've seen that clearly shows an injection wire running all the way from the power source, along side the LED strip to the far end. Thanks for clearing that up!
13:09 - There's an obvious color change for both the un-injected and single injected wiring for the two parallel LED strips.
14:25 - *I* see very little color change when only the beginning and middle injection points are enabled. Shouldn't this look exactly like 13:09?
Thanks so much for watching and I'm glad you liked the video. I went back and watched the sections and you are right. My only guess as to what the difference might have been at the 14:25 point was even though I know I had the limiter turned off, I might have fogot to turn the brightness all the way up on the WLED brightness slider and therefore it was not as obvious as a difference. Good catch!
I like where this channel is headed man. Totally forgot to sub, rectified that now. Cheers brethren.
Thanks so much buddy and thanks for the support! Glad you enjoyed the video!
Just an FYI, you could look into 6 amp "mini-amplifiers" instead of that bulky one with the protruding pins you use, the "mini-amplifiers" are no bigger than a usb flash drive but half as thick, so much easier to hide when you hang your lights, and they do the same function, keeping the remote controls in-sync and are a buck or 2. They also help with injection just being wired into the sequence
Thanks so much for the great suggestion! I've never heard of mini amplifies so I'm very intrigued! Hiding big stuff is sometimes a nightmare so anything to help on that front would be amazing! Thanks so much!
I'm also curious with this if there is a link or the like to these?
Link?
I’m curious too.
@@ChrisMaherDIY Hey Chris, I was wondering, will the animations only work with "Govee" light strips or is it the control unit that drives the animations?. My lights are good quality, but only have the cheesy remote that has like 12 colors and just a few animations (fade, flash etc)
Well done. Exactly what we all need to know and were wondering about. Thank you. I'm impressed by how well the phone charger works. So much cheaper than the big boy option and we all have those chargers lying around.
I bought the exact same RGB strips and I had no idea what to do since I didn't realize not everything was included. Thank you!
Thanks so much for watching! That's a bummer! Yeah with these type of leds you need to have more than just the led strips. In the description I do leave links to everything that I used in the video including the led strips, power supply options, esp devices and wires. Hope that helps!
Dude you are the LED king. Thanks for making these videos so well
Thanks buddy!! Glad you like the videos and appreciate the kind words!
Bro for real you are the man, I have been looking everywhere for these information, nobody explained it this good, you helped big time, love
Ok so I gave this a go .. and how fun is this! I'm gonna invite my mates over with their sons so we can have a LED workshop and make some lights for church. Thanks again :)
Dude this is the best walk thru for this type of thing that i have every since thanks so much for sharing this info. This was exactly what ive been needing to know.
Thanks so much buddy!! Appreciate the support and glad you found the video helpful!
very underrated channel! loved this video..Precise and explanatory! Subbed
Thanks so much buddy!! Appreciate the support!
I'm just getting into WLED and this has been useful explaining runs and the concepts of injecting additional power
Christ is a person most accurate on any project to a successful completed....many thank
Thanks so much buddy! Glad you enjoyed the project and thanks for watching!
Hey Chris, I STAND CORRECTED! Although my mini-amp idea does work keeping 3 strands in-sequence, your wifi board is vastly, ridiculously BETTER for it's functionality, and is so worth it's larger size. You can easily hide the wifi board by simply using longer wires and having it end in anyplace you wish. If you're lighting a bedroom for example, the obvious place is a closet, you'll want to do this with the 60 amp supply unit for sure as it's the size of cigar box. PAY ATTENTION TO CHRIS, I've watched dozens of videos and tried many configurations, power supplies and Chris's video is the only one that is both accurate and user-friendly
Thanks so much for the follow up! I'm certainly no expert so I'm always looking for better/different ways to do things so i'm always glad when people bring up new ideas! But I'm glad that the way I did it seems to be working for you! I appreciate all the kind words my friend! Hope you have a great day!
Pretty sweet, I'm going to start messing with this stuff. I ordered some lights and a controller from your links below. Hopefully over time I can make something nice for my room. I appreciate the time you take to create these videos. I really like your content. Subbed.
Thanks so much! Its a fun hobby for sure and the most fun part is coming up with something in your mind and then trying to make it. I'm still very new myself but if you have any questions along the way I always try to respond to every comment or question.Thanks for the sub!
Hey Chris, you’re a life savior my men I follow another tutorial video and got stuck thankfully your video pop up I was using the D2 pin instead of D4 I really thought I had return all 7 rolls 16ft strip. Thank you brother!!! God bless you!
Also can you please advise on how to chain link 5-7 16ft roll leds
And here I was trying to solder the wires together straight, where twisting them like that gives a much better connection. Thanks!
Thanks so much for watching! yeah the longer i've been doing this the more I realize there are a lot of different ways to go about doing something. I've recently started using Wago connectors for things like this and they are amazing. If you are just trying to connect 2 wires together, these in line ones work great: amzn.to/3XrpXdS
Great videos and great work. As someone who watches tons of DIY YT videos I always skip and X2 the playback in order to sum up the videos. The style you have in delivering your information as well your video cuts and side bar walk-through leave me immersed and following along at normal speed. Great job keep up the great work. Very inspirational 👏 🙌
This was the exact video I was looking for. Thanks so much for the in-depth details.
Awesome! Glad you liked it! Thanks so much for watching and taking the time to comment.
Thanks Chris! Ill use your videos as cuide for my first led addressable project. I was planning to conect 8 10m strips on a big roof. And now I think I will make it. Thanks to your videos, I will start with 1 line and see how it works 💓
Thanks so much for watching and glad you liked the video! For any really big projects like that I always recommend people watching this video from Dr. Zzz. Really good stuff. He is a lot smarter than I am: ruclips.net/video/S0g02o85fGY/видео.html
unfortunately my brain wasn't wired correctly to learn stuff. you came close though
lol I hear ya! Some of this stuff the only way to learn is to just do it and troubleshoot it as you go. Glad I was close though!
You can understand it. I did a bit and i am dumb as a rock. Believe in yourself!
But there ain't no explainin'! Just showin'.
Well done! Very good demo! I am gathering a few things to build my diy wled strip and I was wondering about the power supply, wether I should get a more powerful than my 5V/2A usb charger. Your video cleared a lot the things up. Kudos!
This experiment is really fantastic and well done!!! Thanks for the info !!
I am always inspired with each of your projects. Thank you very much.
Great! I just bought 4 - 5 meter strips , a 60A 300w ps and you proved that I'm going to have to run alot of injection wire to get even white from pixel 1 to pixel 1200.
Thanks so much for watching! I always just test things and start off with no power injection and then go from there based on how things look! Good luck and hope everything turns out great!
@@ChrisMaherDIY Thanks with that thought. I have set up the whole 1200 LEDs in the garage in a test situation while I am mounting the tracks on the roofline so that is ready once I get the power figured out to a bare minimum of wires, injection points etc. PS really love the lighting ideas you bring forward in your vids.
@@graphguy thanks so much! What a fun project your doing! Feel free to send me a video when you have it set up! I'd love to see how it turned out! My email is in my RUclips info
@@ChrisMaherDIY ok . I'm a tad confused. I have 1500 (60/m) 5v leds up in 5 strips. I have power at the start and I added one home run at the very end and that is it. Every single WLED effect works just fine and looks great!
So how come every person says that in that situation I would many injections?
@@graphguy You are confused just like I was and still am to some extent. So when people ask how much power will they need, there is the theoretical amount you will need if you wish to run the lights at full brightness and on white, and then there is the power (much less power required) that is needed if you are only planning on running animations and colors. Thats why I generally say, it will depend on what you are wanting to do with the lights. As you have noticed, you dont need a lot of power to run most animations and if things look good and your happy, then your done! But my guess (and I could be wrong) but if you turn the lights to white and at full brightness, you might see some color/voltage drop and would maybe do some more injection. Hope that makes sense!
Hi Chris, my Leds doesnt turn on at all. do you know why? i followed your instruction.
Too little power
Thanks for another awesome video. Happy new year!
Thanks as alwasy buddy! Happy new years as well. Here's to a great 2022!
I used an old surface tablet adapter with usb and rated at 5v 2.5A. It was perfect for powering my small controller and about 3 strands of 50 bullet nodes. Once I plugged in 2 more strands I saw some drop off but when my sequence hit the all white segement, anything beyond the 2nd strand turned pinkish orange instead of white. These are a great way to see where your drop off will happen. I have purchased a 350w 70A big boy power supply to wire up my tree with (and a few other models) I'm here to confirm my understanding of wiring the injection points and you confirmed I understood it correctly. Red to VCC+ and white to VCC-
Exactly what I was looking for! In my case I'll need about 13 Meter long led strip and I was pretty sure I wouldn't get away with connecting from one side only, but as I never ever touched any led strips had to make sure and I still got time in the home project! Thank you!
You are very welcome! Thanks so much for watching and taking the time to comment!
This had everything I was searching for! Thanks you are the best 😊
Thanks so much for watching and glad you liked the video!! Appreciate the kind words!
This is VERY USEFUL.
It shows how to properly power long strips of LEDs, instead of just powering from one end, then wondering why the strip or matrix burned out!
The wires connecting them together aren't heavy enough to conduct all that amperage through, so you have to "inject" more power through the leads provided.
Great video! Hopefully this will help some of the no-brain Gen-Zers out there, trying to get though life without EVER learning anything except what they call "hacks" that allow then to meander along without ever becoming knowledgeable about anything. Heaven forbid they might accidentally learn something.
And, this was appropriately titled, for a change.
You could've just titled this "Comparison of Power Supplies and Methods of Powering LED strips."
That way, it's easier to find in s search.
I hate it when ppl mis-title their videos, just to get lots of views.
YT should encourage PROPER TITLING, instead of encouraging MIS-titling the way they do now!
It just makes sense. After awhile, there's trillions of videos online, but nobody knows what any of them are about without having to watch each one until you find what you're looking for. That's just crap, and a massive waste of time.
But, hey, does YT care?!
Of course not. They just want VIEWS.
ive held off for a few years because i didnt understand the process of injection, this video made it easy.
I was very confused about my 5m wa2812b 300led/m power supply. solved my problem.. thanks 😊
Absolutely incredible tutorial, definitely subscribing for more and I can't wait to try this out!
Thanks so much for watching and glad you liked the video! Appreciate the support buddy!
Hey it’s been 2 years. Do we need to think about adding fuses for these setup? Thanks
I wish RUclips had more videos like yours. Clear even for dumdum like me, straight to the point but with explanations and practical example for vicarious experimenting. I've had the stupid idea of making one of those "old-telephone lamp" but with an rgb led strip inside, instead of the bulb coming out from the handset. Using an esp32 (that just came today after weeks, and I've never used a microcontroller nor led strip nor made a lamp out of this stuff. So this videos are fresh air for my noob brains. Thanks
Great video! I would like to add something to this.
You used 5m 5V 60 led/m strip. 1 meter consumes 18W at full brightness. That means that you will need 3,6A for full white. With 5m it will be 90W and at least 18A power supplier will be requaired.
1A=1W / 1V
1W=1A * 1V
1V=1A / 1W
easy math ;)
It also recommended to have addicional 10% of power in your project. Just for LEDs. With 5V power supply You can power up your other 5V devices such as HDMI splitters, raspberry pi's and so on.
Thanks so much for watching and for the great advice! That does make it seem simple!! Appreciate you taking the time to share your wisdom!
❤❤❤
Lovely comparison among 3 different types of power sources and their affect on the LED lighting and power injection - love it
❤❤❤
Thank you for all of this high quality information. Very unfortunate that I will need such a big power supply every 10m
Does the 3-wire extension cable carry the 5 Volts over a distance of say 6 meters without noticeably dropping voltage?
Thanks so much for watching! I have not tested out that length yet but my guess is there would be minimal noticeable drop in voltage. I could be wrong but that's my guess! If I ever test out things with that length, I'll let you know!
Great video sir! For a newbie like me, I was looking for a video to show how to connect to an ESP32 board. Thanks for doing that!
Do you recommend setting up a STATIC I.P. ADDRESS for LED lights?
Great video. Really helped me with a closet lighting project I want to do.
Thanks so much and glad you liked the video! Thanks for watching buddy!
Excellent tutorial! Thanks!
You are very welcome! I'm glad you liked it and thank you so much for watching!
Dude You are just awesome. Much Love!
Thanks so much for watching and taking the time to comment! Appreciate the support buddy!
Question: I always thought the extra 2 wires off the led strips (the unused ones) were for power injection. If so, couldn't you use them for power and then just plug data and ground from the esp to the plug?
note to self, watch whole video
You are 100% correct. You could certainly use the extra 2 wires at the begining to feed the power/gnd since they are soldered to the exact same pad that the ones I used were connected too. I never know how detailed to go in someo of these videos but thats something I could have definitly clarified. Thanks for watching buddy!
Yeah I have some of mine setup like this. Power supply connects to the power injection wires and then I use the JST connector to connect to the ESP8266 for power, ground, and data
Thanks for the video! I’m following the 3rd method and after wiring everything up and plugging it in it would appear the power supply isn’t getting power. If I power the ESP board via USB both the ESP & power supply have LEDs turn on, but nothing is happening when plugging in via the power supply. Any suggestions?
EDIT: I had to switch the power supply to 110v. All good now!
Thanks so much for watching and glad you got it figured out! I actually did the same thing one time. Drove me nuts until I realized what it was lol.
Do I need to program the 8266 board prior to installing them? Thank you.
You just need to install WLED onto the 8266 board before you will be able to control the lights. Here is a video I made going over how to do that. ruclips.net/video/l8OMi7SMpqs/видео.html
Very clean and analytical , good job
Question, the data wire does not have to be connected to additional strips? I can not get any info anywhere about the DATA wire, so as long as its connected once to the strip I can inject power anywhere and be good? so no need to connect the yellow or sometimes green data wire to the rest of the strips?
I am planning on connecting ten 16.4 ft together. Do you know if the large power supply in the video will work?
What is the largest current the esp32 can handle while not destroying the board?
Thanks a ton, this was really helpful for a house exterior lighting project I'm doing. 22 meters of 30 led/meter to illuminate a white house with seasonal colours.
Thanks so much for watching! Sounds like an awesome project!!
Are you running this with more than 1 Node MCU? I was wanting to do similar, wasnt sure how many strips could be run from one NodeMCU, and was not sure if I was going to need 2 60 amp power supplies as well. I havent seen a video of 3-4 strips hooked together.
@@mattglandorf9600 nope, just one and I've had no issues with processing power or anything like that.
@@mattglandorf9600 FWIW, I initially picked up a 60A psu because I did the math incorrectly. A 10A would have worked but it turns out a 60A was cheaper so I stuck with it. How many LEDs are you trying to power?
what is the longest run you can do with the 60a power supply ? and using all 3 power feeds from power source?
Thanks for watching! Thats a good question! I have yet to try maxing things out but I think you would probably reach the limit of WLED before reaching the power limit if I had to guess. That would however be a fun thing to test out! Here is what WLED say about max number of leds on the esp32 device (esp32 is a little more powerful than the esp8266)
ESP32
There is a maximum of 10 strips supported
Contrary to the ESP8266, the pin usage does not matter on ESP32, feel free to use any available pin
For perfect performance, it is recommeded to use 512 LEDs/pin with 4 outputs for a total of 2048 LEDs.
For very good performance, it is recommended to use 800 LEDs/pin with 4 outputs for a total of 3200 LEDs.
For good performance, you can use 1000 LEDs/pin with 4 outputs for a total of 4000 LEDs.
For okay performance, you can use 1000 LEDs/pin with 5 outputs for a total of 5000 LEDs.
For okay performance, you can use 800 LEDs/pin with 6 outputs for a total of 4800 LEDs.
ESP32 can calculate about 65k-85k LEDs per second (that means 1000 LEDs @~70fps, 2000 LEDs @~35fps, 4000 LEDs @~18fps)
4 outputs seem to be the sweet spot.
i have a dumb question. If i have enough power, can i power up 2x (ESP32 + Led) with only 1 power supply ? so 1 x power supply (5v 10a) -> 2 x ESP 32 with 1m led
Do you have to use a different channel on the power supply when injecting power?
You dont have to! You can use the same one.
@@ChrisMaherDIY awesome thank you! Want to get all my ducks in a row before I pull the trigger on $300 to get some sound reactive LEDs in my game room. Your channel has been paramount in helping me learn what I need to. I appreciate your efforts and your reply!
Instead of using Wago connectors and twisting wires to connect them, can We solder the wires together for a less costly option?
Also the 3 Pin LED Extension Wire 20 AWG,for WS2812B be used as normal wire for other projects such as connecting wires to a a esp board for example?
Appreciate your tests and info!
Thanks for watching! Yeah you can for sure solder the wires together! And yes the 3 pin connectors will work just fine for that!
Thanks. very interesting video. It answers some of my questions regarding power injection, power supply to use...
You are very welcome. Thanks for watching and i'm glad you liked it! Appreciate the support!
Hi chris. Bit of a problem here. I’ve connected my esp32 board with wled installed. I’ve connected the jumper cables from the board to a 5v, 5 metre consisting of 60 LEDs per metre. I connected a micro usb like you did on the esp board. The light on the board stays on aswell as the last led on the roll without any others working and when connected to the wled no luck with any of the strip working except the last led. I’ve got the ground on the right pin, I know I need more power injection but I’m just trying to test out the setup to see if it works before I connect the power. In your video a 5v Samsung charger seems to work. Any help recommended please. The direction of the LEDs are connected right aswell.
Nice video, thx. What to do for a 40meter run? Can it be done?
Thanks so much for watching! It for sure can be done. I have still not done anything that big but it is for sure on my to do list for videos. I know WLED has a certain limit that they recommend when it comes to LEDS kno.wled.ge/features/multi-strip/ But when I do get around to doing a big install like this, I'll for sure make a video of it and then hopefully i'll know a little but more on how to go about setting something up like this!
Thank you very much 🙏 i was struggling with the right power supply.
Would the phone charger be enough for using the strip as ambient lightning?
I think it all depends on personal preference. Now there is certainly a limit of leds that will work with a phone charger (not 100% sure what that limit is) but the lower the brightness you have the leds set to the more leds will be able to work and look accurate. I would just do some trial and error. Start with 50 leds and play around with the brightness and see what you think. If it looks good, add more leds and keep testing. Thanks for watching!
@@ChrisMaherDIY Thanks a lot!
What about fuses? Should I add a inline fuse? Do you have a video on this topic?
Thanks so much for watching! I've never added fuses to any of the projects I've done. And even though I have never had any issues at all, its still probably a good idea to do. I have not made any videos on this process but it is something I do want to make a video on in the future.
@@ChrisMaherDIY Thanks! i would love a guide to follow on that, would be very helpful! looking forward to it!
does this apply to 12v led strips? i thought i you had to cut the positive from the strip before adding power injection because you cannot have two positives? or maybe i misunderstood. is this right?
Thanks so much for watching! This is only for 5v but a lot of what's shown here is very similar on 12v strips. I made a video going over a little bit of a 12v setup: ruclips.net/video/zbhdH-qSANc/видео.html
Solid video and much appreciated for the demonstration.
Thanks so much for watching and taking the time to comment!
Just to make sure that i am fully understanding here, you are putting power to both ends of each led strip? I am in the process of putting these strips around our bonus room. Is there a wiring diagram that i can see?
How would you mount that power supply unit so it isn't sitting on its shell? Having a hard time figuring out the search terms to differentiate these power sources from PC power supplies, etc.
That's a good question! I'm also not too familiar with pc power supplies so I'm afraid I'm not much of a help on this topic. Maybe someone else reading might know and can chime in!
When power injecting into another LED strip, do you need another module to control the lights?
No you should not need another module as long as the two led strips are connected by the data wire. If you are not going to connect the first led strip to the second with the same data flow, then you would use another module for the second led strip.
Ok so I am running a molding style strip in my sons room where the wall meets the ceiling. Using the 30 mill corner channels. I think will be using strips with 30 led’s RGB no white per meter and it is a 44’ linear run around the perimeter of the room. If the four corners of the room are
A B C D and I have my power supply and esp32 start at corner A. can I run all the way around and inject power at the end when it gets back to corner A? Also what power supply would you guys suggest? Tips and suggestions appreciated this is my first LED project
Thanks so much for watching and great question! I still have not done any large projects like your mentioning but If I were doing this I would first test things out on the floor and probably start with a 5v 30a power supply (assuming your using 5v led strips) and have power at the beginning and then at the end, turn things on and see how things look and go from there. Being that your using led strips that have 30 leds per meter, my guess is most animations would look just fine like that but would probably see some voltage drop in the middle if you are trying to run them at full brightness and power. But I'm certainly no expert so I would also love to hear what others would do!
Yo chris what or where do you connect the backup data if you had one? or can u leave it out completly?
Thanks so much for watching! Here is a video I did on a 12v led strip that has the backup data pin: ruclips.net/video/zbhdH-qSANc/видео.html I think most people either just add the backup data to the gnd or add it to the regular data. I'm not sure what is best but I would try one of those two options!
@@ChrisMaherDIY Thanks a lot chris.
Do i still need to power the board with the usb cable, or will it just take power from the dc adapter through the vin and gnd pins connected to the female dc?
Thanks for watching! You can definitely power the board with the dc adapter. I think I go over the way I do it in this video: ruclips.net/video/TOEnFKLm9Sw/видео.html
@@ChrisMaherDIY thanks, very helpful 👍🏻
Chris how many 5m ws2812b can I connect to this power supply ?
Can you inject power at the end of say a 70' run with a second PS vs. running a long railroad length of wire from first power supply?
Do the same power requirements apply for the COB strips? (amps needed per number of leds)
Thanks so much for watching and that's a great question. I think it would be very different just based on the lights that cob strips have vs the individually addressable strips. I think wherever you buy them would have the specific power requirements of that particular strip.
i have a question if i need 3 led strips same with the one you test . do you think one power supply 300w will work ?
That should be perfect for 3 led strips! Probably need 1 or 2 injection points of power depending on how bright / if you want them to be all white. But if you are mostly wanting them to be displaying different colored animations, you could probably get away with just 1 injection spot.
I have a pantry that I am putting leds for lighting. I will (8) 36 inch sections. Can I connect 8 wires together and connect that to the controller.
I have setup like setup #1 with a USB power Supply with microUSB powering the LEDs and ESP8266 board. The boards constantly fail. I have gone through 3 already and am not sure what is causing it. It is around 140 LEDS and 5v3amp power. I notice in WLED it says "Keep at
Thanks for watching! Yeah I would keep the limiter turned on and try setting it at 1000mha if you're going through boards like that. See if that makes a difference!
@@ChrisMaherDIY Thanks for the quick response. So technically even method #2 should be limited to
Setup 2 you should be good. I think the issue comes from too much through the micro USB on the board. Setup 2 doesn't have anything plugged into the micro USB. I've only ever fried a board when I accidentally connected the esp32 to a 12v power supply!
Im a total novice to this but very intrigued. Does the power injection need to be added at the end of each strip or can it be daisy chained to the next strip then back to the power supply at the end of the run?
Great question! You can add power wherever you want. So you can daisy chain 2 strips together and if necessary, add power to the end of the second led strip. I will always test things out with no power injection and see how everything looks and then go from there. I'll inject power if necessary. Let say you connect 5 long strip together and inject power at the end to go along with the power at the beginning. My guess is that the LED's in the middle of those 5 strips will be a different color since the power is not getting to them with as much as they need so you would more than likely need to inject power at around the middle point so that those leds will have enough juice. Hope that helps!
you made it all easier in my head but how much will i need to power up 2160 leds that i can only inject power in the end?
Thanks for watching and taking the time to comment! I've never built anything that big but the power supply I linked to in the video (the big one) is about as big as they come. The led lights can only take so much power and there will always be voltage drop that unfortunately wont be able to be avoided by simply using a bigger supply. The best advice is to wire everything up and see how it looks at different levels of brightness. It may work for what you need it to at a lower brightness with power injection only at the end but my guess is you will need to somehow figure out a way to inject power at different points with that many leds.
@@ChrisMaherDIY thank you so much for your response after looking into my project more i found out i only need 900 leds so i think i will be ok :D
Thanks for the super informative video, exactly the info I was looking for and struggling to find.
Do injection points need to be soldered onto the strip itself, or if I have extension wires connecting multiple strips I can insert it into the middle of a string of wires?
Thanks for watching! You can inject them in the middle string or wires!
What conntroler you use? Can i mix diffrent led strips? What are the white and red wires on strip dat you not use? Sorry for my bad eng language.
You can do some mixing and matching as long as they were the same type of strip and same voltage requirements. The extra white and red wires are there in case you want to inject power into the led strip you can just connect the injection wires to those! Thanks for watching!
@@ChrisMaherDIY thank you. I have one set from aliexpress, and one from amazon. I am new to addresable led strips i don't wont to burn them :)
Sorry if it's a nood question but don't we need a stepdown convertor for the esp chip? Won't it get fried when so much power is running through it?
That's a great question and I'm not entirely sure on the answer. I've never used a stepdown converter for any of my projects and I've never had any issues with the chips getting fried. However, I've also read where you should use a stepdown converter. So I don't have a clear yes or no answer other than it probably is a good idea to use one even though I have not and have not so far had any problems.
Hey man, I know it's a bit of an older video but i was trying to get your opinion on something. I want to run those EXACT same LED strips along the top of my room through diffuser channels, and i was planning on using the big power supply and power injection run through the channels. The main issue for me is the fact i'm using 3 5 meter strips (60led/meter) in total to wrap around my whole room. I am unsure if this power supply can fully power all 3 strips connected together, and if the controller would be able to be used for the whole thing? Would I need more than one controller? Thanks!
For some reason after i plug the live and neutral my -v and +v does not have any power. And the led on the source is green . What can cause that? I can’t test the led strip as there’s no power coming out on +v
I could really use some help. I have Two WS2812B . I connect the connectors and can’t get the 2nd light to come on. Are you saying I can inject power from the red and white wires (the ones I’m not using) from either end? Why doesn’t any power carry through the 3 wire connector? Why do I have to use the red/white ?
quick question to connect 20 meters of strip ( 5 meters sets x4 ) do you recommend 12v or 24v? i will like an option i can use a single power supply to power all 20 meters from the beginning - i assume at the end of each strip i will connect the data cable to the data cable of the other strip ? also a single controller can run all 20 meters correct .. thank you so much for all your time and videos.
do you know any controller that will light the leds in a linear effect? in the same way to turn off (but in reverse).
Thanks so much for watching! I'm not quite sure if this is accurate but I think you can assign the lights to turn on with a certain animation. I'm not sure about turning off with a animation in reverse though. Maybe someone else reading the comments might know for sure? I'm also not sure if there is a different controller out there that can do this.
Hey Chris. Do you know if this will work when the phone is offline again?... trigger in app and log off... or does it need a constant signal from the app?
Thanks so much for watching and great question! So when I have the lights on and lets say my phone turns off. The lights will just continue to do what they are doing.
@@ChrisMaherDIY Thanx so much. Doing an off-grid project in a desert next year. This seems like a perfect setup
Super super interesting, thank you for that break down!
You are very welcome and thanks so much for watching!
I've learned SO much from your videos!! I purchased this power supply to run 3 strips of WS 2812B (900 LED's). I have power running to the first led strip, and another power injection connected to end of the 900 LED's. It works great, exactly what I needed. My question though is do I need to put a fuse on both positive wires coming from this power supply?
Can the 3rd led power unit be hardwired in. It looks like it to me as you can just skip the plug and wire it in the junction box in a wall. Also, can multiple strips be wired in one unit?
DUDE. Thank you soooo much. You just answered sooo May questions. Definitely subbed. Thank you!
You are very welcome! Glad you liked the vidoe and thanks for watching!
What about if you want to add two 5V sensors, let's say for the top floor of the house and the lower floor (so the sensors enable and/or disable the lights); would you still be able to connect both sensors with the second option (10Amps) with one 300 led strips and your led controller, or would it require a bigger power supply?
can you use more than 2 injections with the power supply?
Thanks for watching and you for sure can!
