Actually, what i can see is both of them are cheaped out. The multi smd led version is usually a scam on wattage (for example: if a 5730 smd led style lamp uses 20 led, that is only a 10w ledboard in it, since 5730 leds are max. 0.5w each), but on the otherhand its heat production is spread out on a larger surface, so the heatspreader don't have to be so effective(though it brings the question, if they thermal pasted that large ledboard enough and attached it to the housing correctly for good heat transfer)(usually not, and that's what kills them so quickly). The single led chip version is also got a lot of scam nowadays. They usually cheap out on the housing as well, but here its got a much more dramatic effect on the lifetime of the lamp. Since here all the heat generated, comes from a considerably small point, the super thin casing(i've seen dead lights with only 0.5mm thick back) can't keep the led cool enough, so the constans 80-120ºC kills them in days(it adds to this overheating problem, if the led isn't even placed in its place and screwholes correctly in the factory) What you couldn't measure accurately in the video, is the actual led temperature in the middle, because of the bulky driver housing on the back. Note, what i described above is something that i learnt throu my hobby, and a lot of faulty floodlights that have been given to me by others. If you're looking for a light that will last long, either buy from a trusted brand, like Osram, Philips etc. and hope for the best Or buy a cheap light (but look for the cooling thins on their back, cause there are some lights on the market, that are absolute garbage beyond something that worths the time and effort) take it apart, take out the led, sand up the heatspreader surface with fine sandpaper til it gets somewhat shiny, drill the led mounting holes deeper and thred them, add new thermal paste to the led and screw it to its place tightly with NEW srews(the original tiny screws always break into the hole, don't ask me how i know this) Have fun :)
Quick question...what do you do with the fish when you're done? I'm getting a little rig together (1542) to go bowfishing with my kids but not sure what do do with all the carp
5 years later. Can you talk about longevity? That is in a very very rare occasion that you actually ran these lights, which one survived better and for how long?
I know this video is old but to contest for the cheap 100 watt I bought one 3 years ago for 13$ and mounted on my shed in my backyard and it lights up the yard pretty well actually has been used frequently even for longer periods of time in Texas summer been rained on countless times and still works great
Gary, have you tested the swamp eye LED yet, from outrigger outdoors? On paper looks like it would out preform most other LEDS but can't find any videos actually testing them.
One thing to look for if you are trying to penetrate water is the color of the light. What penetrates best is bluer light. Often called cooler but higher Kelvin. My guess what might be a good choice would be these bluish headlight LED bulbs in one of those off road wide beam reflectors. Have you heard of any one using such S setup? 12v would make it easier to Irvin a boat I would think.
Being a bit pedantic the actual power depends on the power factor, but your point about just wanting to know how many your generator will run is very valid. Your meter might be able to measure power factor, some clamp meters do, but you need to use the probes and the clamp simultaneously.
single Chip or COB lights are not preferred in high temp countries as the heat dispersion is not that good its more pointed hence more chances of failure in comparison to SMD multi chip lights but yes Heat Sink Vains has to be thicker and higher. Every Light performs well in its start so if you want to have actual results test them after at least 3 months of similar usage and prefer model and brands that gives you most warranty.
Don’t mean to troll, but do you actually get 120V coming in? If your going through the effort of accuracy, measure the voltage across the terminals. For example, I have 110v in my outlet.
All LED lights work on low voltage. I'm not sure you can assume that the input voltage is powering those LEDs in either light. One things that you can do is use a power meter to measure the actual overall power consumption of lights and indeed any electrical device. These power metres also measure the Load Factor. To be entirely accurate not all the power will be converted to light and a small amount will be used by the electronics hence the heat generated in the electronics. Nice vid.
Gary Briggs I think that's the input voltage not the voltage the LEDs are using. LED lights use a maximum of about 3 volts per LED. At about 120 volts the implication is that all your lights have 40 LEDs in series. eBay sell cheap power metres that read directly in watts.
yes voltage multiplied by current gets you watt consumption. but agree with previous person you need the voltage draw of the led. led lights do not use ac power. there is a board behind the led that converts the ac to dc.
in the interest of accuracy, you should use your meter and measure the actual voltage, not use 120. voltage can range quite a bit from 118volts to 125 volts .depending where you are on the grid. excellent video as always
Those ebay lights are $14 now... that makes their slight difference in efficiency a bit more tolerable, especially for on grid use. In dollars per lumen they're great.
The Lemon 50 watt is available on EBay for $20 with free shipping. You can also get a 100 watt for $35. Why get junk when you can get something good for the same?
Lux is the intensity of the light at one point not the total amount of light produced. The eBay light could be producing more light but it might be more spread out. I agree with you that the EBay light is junk however you might consider thinking through your test procedure. For a flood light one wants a wide area lit up evenly. A projection on a screen or wall might make sense. The measurement you would also want would be lumens. This would be the total light produced. This would be a harder measurement to make. Maybe take several measurements of any area and take an average. Most likely there is better way but I don't know what it is.
Stanley Tolle i have no idea if you're into Bowfishing or not but, this this is tailored to Bowfishing. We're trying to maximize useable light penetrating water. Total lumens isn't the be all and end all. Typically guys run 8 to upwards of 20 lights around their boat, with a lot of overlap in the flood patterns of lights. All these tests are just to show the difference between lights commonly used by Bowfisherman, general brightness compared to each other and most importantly the power demands. Knowing exactly home many lights you can run off a 2000w generator is very important.
I'm sure someone else has said this, but I see you are making a very good effort to remain scientific. The problem is that you assumed a voltage of 120. For your next tests you should read actual voltage. At a mere 100 watts I doubt that there will be any appreciable voltage drop, so an initial voltage reading should do. Based on your consistently high wattage calculations, I'm going to guess that line voltage was closer to 110 VAC. Good video!
Can you still get these lights? The link takes you to a different looking light. Looking for something similar priced and brightness unless there is a better light available now.
Trea Coffill for the price of 2 deep cycle batteries and the inverter to convert DC to AC you could buy a small 1000w inverter generator and run 15 to 18 50w lights.
Can you do a comparison video with a carplite running on an inverter and check the efficiency new company very cheap but look good and comes with filters 100 watt LEDs are $40
+MN Outdoor Boyz comparable quality, comparable brightness. The Ledmo is slightly smaller height and width wise but deeper. I need to test the LE for amps to determine which is more efficient. Both great lights for the money.
Power factor is allso very important when you run stuff from generator (low power factor overheats electric generator windings and causes bunch of other issues, and messes up with voltage regulation so you get high voltage spikes on some generators, which can damage electronic stuff like computers/laptops/chargers etc if they are plugged in, or cause engine to ramp up and down constantly on some poorly made generators). There are many cheap devices available, similar to KILL-A-WATT, that plug between socket and device, and measure voltage, current, frequency, watts and power factor (should check specs what they actually measure), and perhaps simpler to use than clamp on current meter...
i think you find when they say its 50watts or 100watts what that is based on is the led chip will have 50 tiny leds or 100leds in the future you'll prob have 1000s of leds within one chip being brighter and more efficient, their basically thinking 1led equals 1watt, if you look close at the led chip before buying you wanna buy the one that has a clear blueish gel over the led there twice as bright that one there with the orange gel really is a cheap chinese chip
Thanks for all the effort you put in your videos they really help! I have one quick question, what would be the smallest generator that could run 8 of the 50watt LEDMOS? I'm trying to save a little on money which is why I prefer the smallest size.
Gary Briggs +1 for a power meter such as killawatt. Your method is good, but replacing an ammeter with a power meter will reduce the uncertainty even more. LED power supplies are very nonlinear, so there might be 10-20% error between wattage and VAR.
Just because one light is using more wattage of electricity than another light doesn't mean it's putting out more light! It all depends on efficiency! I have a degree in electronics so I'm not just giving you a hard time LOL
Very informative and much appreciated. Going to pull the trigger on 10 LEDMO's from amazon unless you have recently found something recently that you feel works better.
+DarrelErnheart best light I know of under 30$. I don't advocate for inexpensive 100w lights because of the heat issues. This light is pretty solid and Amazon return policy is very good.
Gary Briggs again, greatly appreciated the input! I was originally going to go with a 12volt set up. This may be a completely different animal for you but if you have any input on 12 volt vs 120 and the size generator I would need to run 10 of the 50 watt ledmo lights that would really help.
WOW What a difference. I just watched a video using 150W EBAY LED LIGHT AND IT PERFORMED WAY BETTER THAN YOUR EBAY 100 WATT.. STILL DOLLAR FOR DOLLAR, THE 50 WATT LIGHT WAS BETTER.
What in the actual fuck.. no this doesnt help.. At fucking all.. Instead of showing at what angle and how bright and far it lights up he shows us the fucking luxmeter as if it was the absolutely most important thing in the world when it comes to lights, what brings me back to: what in the actual fuck...?
Thanks Gary, I was in the process of ordering a LEDMO 100W. I have had good service from some of their candelabra bulbs with an LED "corncob" in them ruclips.net/video/HPXSI_zhGdc/видео.html . Your tests help ease my fears of getting new lighting for the back yard. I still have five incandescent flood bulbs mounted on the back of the house that have been mounted there for decades. I can almost hear the coins hitting the pavement when the yard lights are on. Time to bring them up to the 21st century.
this one is only 4mm thick its ip54 its only 25w and its fahr way better than this you shows right now any of this two. allegro.pl/led-230v-naswietlacz-led-ip54-mega-jasny-led-cob-i7484261697.html
Thanks for test comparison. Most Chinese specs are so fraudulent and exaggerated. I bought one of those clamp over amp testers from Harbor Freight. Now to find a video to test how unreliable the China crap test meter readout is.

Not available any longer, check out the 50w Viugreums videos
Could you run, let's say, 6 50 watt LED lights off of a couple deep cycle batteries, or would it just drain the batteries dead?
Trea Coffill for the price of 2 deep cycle batteries and the inverter to convert DC to AC you could buy a small 1000w inverter generator and run 15 to 18 50w lights.
Can you do a comparison video with a carplite running on an inverter and check the efficiency new company very cheap but look good and comes with filters 100 watt LEDs are $40
that looks much warmer than 3000k, maybe it looks different on camera but can you confirm that it's closer to maybe 2300k?
Emmanuel Ceballos it is advertised as 3000k, 2300k is more orange and would look like high pressure sodium's.
I see, thank you... I just realized i had f.lux activated on my computer so everything looks warmer in color
Would the seelite 50w bracket fit the ledmo?
How would you say the LEDMO compares to the LE 50W? They are similar in price, but how is the performance comparison?
+MN Outdoor Boyz comparable quality, comparable brightness. The Ledmo is slightly smaller height and width wise but deeper.
I need to test the LE for amps to determine which is more efficient. Both great lights for the money.
Sounds great. Keep us posted on what your amperage testing comes up with.
+MN Outdoor Boyz I'll make a whole new video, adding in the amp test on all the lights
Sweet, looking forward to it. I bought one of the LE lights due to your videos, great work.
