- LED bulbs measure brightness much differently than incandescent bulbs do. Some still believe wattage equals brightness but in today's world, lumens are what is used to measure light output. While wattage is still useful to know for energy cost, it no longer is an accurate gauge for brightness.
Because LED lamps are up to 85% more energy efficient than traditional filament bulbs, the correlation between "more watts = brighter light-bulb" no longer applies. We use lumens to measure the brightness of LED lighting products like lamps, so "more lumens = brighter LED lamp". Our educational video explains the new way of measuring the brightness

As always folks, thanks for tuning in!
So thorough and easy to follow. I’m confident, that I can purchase the correct light bulbs on the first visit! I was completely clueless. Thank You, for making this easy to understand. I watched about 3-4 videos before i found this masterpiece.🎉
I'm thrilled this was helpful to you, Queen. Thanks so much for your kind words!
Kelvin - color
Lumen - brightness
Watt - energy
You got it, LSAOA.
I am so glad you explained this. I looked at several videos and this was the first one that made it very clear. I'm buying lighting, and looks like most are 60W max these days. I'm concerned about the light given off, so I need to look at the lumens on the bulbs. The lighting fixtures do not tell you the max lumens, only the bulb does. Thank you!
You are most welcome, Jane. The lighting industry snuck these changes by us all lol.
Thank you
GREAT INFO!! I had no idea watts went out the window for bulbs. Thanks SOOO much! This saved me from buying the wrong light!!
Happy to help 💡
A good explanation of what Kelvin, Watts and lumens mean. Enjoyed.
Hey, thanks, Terry. Technology is always changing!
This was so helpful for my school assignment Thank you!
Glad it was helpful, Icey! I hope you rocked it!
Thanks for the info with the easy to understand graphics!
Glad it was helpful, Emac! Thanks for the kind words.
Thank you for sharing this information 👍 Just and FYI, at 3:43 Energy is spelled incorrectly. Excellent presentation 🍻
Arrrggg...nice catch, Andrew. Your the first one to point that out to me. So much for my proofreading skills lol. Thanks for the kind words.
Been needing to understand this for buying some professional ighting, appreciate it !!
Very cool, Josh. You are most welcome!
Charlie : I am a teacher, teaching energy reduction ( common sense Science ) ....... I am teaching on Light now, and your VID was really great at making sense of the various Warm / Cool lights and how much energy they consume..... Thank you so much.
I must say, Brian, that is perhaps THE best compliment I have ever received in my five years on RUclips! Thank you so much for your kind words!
Very thorough and easy to follow, thank you!

Yes. I learnt something today~!
Thank you very much Mr Charlie.
Very cool, Eugene. Thanks for the kind words!
Thank you for this video. I'm looking at buying some lights, and I understood Watts and Lumens, but the 4000k, 5000k, etc.. I was thinking what does that mean. Thank you for taking the time to explain it.
My pleasure, MorningOwl. These new terms are way different than what they have been in decades past.
I had zero clue this was a thing. Brilliant!
Yep. They changed it all about 4 years ago.
Thank you sir , this was VERY HELPFUL… was looking for the brightest fog lights, unfortunately was looking at wattage 🤦🏽♂️😫
Glad it helped you out, Kay. They just added a new CRI rating to the information labels too. More has changed in the last five years with light bulbs than any other period minus its inception.
This video is awesome and straight to the point !!! 💙🧡
Thanks for the kind words, Lakay! I'm happy you liked it. 💡

Generally speaking, for a small home office (with computer) which K rating is best? Im currently using 3,000 K bulbs and this doesnt seem to be interacting with my monitor well.
Choosing the right lighting for a home office, especially when using a computer, can make a big difference. The 3,000 K bulbs might not be the best fit for your setup, especially if they're not interacting well with your monitor. Consider trying bulbs with a cooler temperature, around 4,000 K to 5,000 K. These temperatures tend to mimic natural daylight and might create a better harmony with your monitor, reducing eye strain and providing a more comfortable workspace. Experimenting with different color temperatures could help you find the perfect match for your office setup.
dude it finally makes sense!!
Brilliant! Happy to help, Scheraq.
MacDonalds just replaced the dining area with ceiling can lights removed the nice T8 10,000k lights
Very cool. I know Lumary has a brand new canned light that has a rainbow AI chip in it. Those will be the new fade, I think.
Thanks, that was really helpful
Glad to hear it! Thanks for the kind words, Mr. Adadoo
Question: If a 60 watt equivalent led bulb uses only 9w and the socket is rated for 60w regular bulb, Is it possible to use a larger lums bulb without over lamping? Need some advice on this one. I was talking to someone and they said to only use the equivalent. Another said that I should go by the socket Watts rating. So anyone know which it is?
Great question, RGO! In this case, it's generally safe to use a 9-watt LED bulb in a fixture rated for a 60-watt incandescent bulb. The '60-watt equivalent' label means it produces similar light output with significantly lower power consumption. As long as you stay within the fixture's maximum wattage rating (60 watts in this case), you're good to go! It's a more energy-efficient option. Just be sure not to exceed the fixture's wattage limit to ensure safety. If you're looking for more light, you can explore higher-lumen LED bulbs while staying within the fixture's wattage recommendation. Hope this helps!
Thanks very helpful!
Thanks, Zaahir. I'm glad this was helpful for you. Thanks for saying so.
@@ChristmasOnCrestline and I meant it 🤝

Thnx a lot.
Anytime, Avinash. I do love to talk about lighting!
Replacing kitchen led flood light. Bulb says 50/60Hz. Is this same as 5000/6000K? AND 2values implies dimmable?
Also 800 lumens and 13watts. (Ok with these numbers). I’m considering replacing all 6 bulbs. Thoughts?
Hey there, Jerry. Those are some great questions. Let me answer those for you. It sounds like there's a bit of confusion about the information on the bulb's label. The "50/60Hz" on your bulb refers to the electrical frequency, not the color temperature or dimmability. Hz stands for Hertz, which measures the frequency of the electrical current. The two values (50Hz and 60Hz) just mean that the bulb can operate on both frequencies, which is common for compatibility with different electrical systems worldwide. This doesn't indicate that the bulb is dimmable. Dimmable bulbs are usually labeled specifically as "dimmable." Your bulb's 800 lumens and 13 watts show it's bright and energy-efficient. If you're happy with the light quality, replacing all six with the same specs is a good idea. Just make sure to check if you need dimmable bulbs if you're using a dimmer switch. I hope this clears things up! Let me know if you have any more questions.
Well done
Thank ya kindly. I'm happy you liked it.
Good Video clip; Still wondering on Security camera it says 65k Kalvin's in brightness, So for my simple understanding in comparison. Would that be as bright as a Daylight bright LED 60 watt 75 watt or 100 watt. Thanks for baking it down to something simple to compare to. Your great Thanks in advance. Or perhaps I just need to ask what a 6500 K equal in Lumens?
You're close, Boss. Kelvin is the color range of a white light. So, yes, it would be comparable to a daylight looking light source. Kelvins don't really equate to Lumens though. Kelvin is the color of white light and Lumens is the brightness that light is seen at. For a security floodlight to have a 6500K rating, it means the light source will not be yellow like a 3000K and it won't be bright blue, like a 10,000K light source. 6500K is a really nice daylight light color. Which also works really well for security cameras too!
@@ChristmasOnCrestline Thanks a million for getting back to me>>>
Thank you so much
You're most welcome, Fabian! Thanks for the kind words.
good video
Glad you enjoyed, Senzu!
So the higher the Watt the more energy you can save on your light bill?
Close, Alley. Lower the watts equate to lower energy bills.
I would like to know what color would this 26W LED integrated 3 color option 3000, 4000, 6000 look like? Warm sun, or blue bright?
Hey there, Linda. The video shows several color samples that displays the color and the K rating at the same time and shows you exactly what color to expect. But, to answer your question, 3000K: This is considered to be a warm white light. 4000K: This falls into the category of neutral white light. 6000K: Is classified as cool white light, sometimes referred to as daylight white. The lower the K, the more yellow it will seem. The higher the K, the more blue it will seem. I hope that helps!
Hello, i have a stairwell shelter of around 20m2 and bought 4 24w led light of 2160lm to put on one side of the roof and the other side.. will it be too bright?
Hi there, DJ! Thanks for reaching out and sharing your lighting setup plan for your stairwell shelter.
Based on the information you provided, you've chosen LED lights with a total output of 2160 lumens each, totaling 8640 lumens for all four lights. The brightness of your lighting setup will depend on several factors, including the height of your ceiling, the color of your walls, and personal preference. However, in general, 8640 lumens might be quite bright for a 20m² area, especially if the lights are positioned close to eye level.
To ensure comfortable illumination without causing discomfort or glare, you might want to consider dimmable options or installing fewer bulbs. Alternatively, if the lights are dimmable, you could adjust them to a lower brightness level that suits your needs.
It's always a good idea to test the lighting setup before permanently installing it to see if it meets your desired level of brightness. Feel free to experiment with different configurations until you find the perfect balance of brightness and comfort for your space.
I hope this helps & let me know if you need any other info!
@@ChristmasOnCrestline thank you for your reply. yes, it is going to be shalter with stairwell, so bottom stairwell going to be about 4m so light travel going to be quite far, but it concern me when you climb upstairs so light going to be much closer to eyes but it is going to be behind. when you go down stairs lights going to be from le left and the right.. but yes, i am thinking about dimmers 😉 i would be happy to send picture of what i mean if you give me email or so, thank you!
I have a light meter app, it reads “lux” and “fc”?
I’m looking for a good light for my houseplants.
I have a 5000k bulb that said 1100 lum.
It seems really bright, I don’t want to burn leaves.
When I did the light test, it read 24,530 “lux” and my actual plant grow light only reads 1690 “lux”.
What is lux and fc in relation to lumens? Shouldn’t the plant light have been brighter? I’m confused.
That is a great question, HC. Lumens measure the total amount of light a bulb emits, like how much water comes out of a hose. Lux and foot-candles (FC) measure how bright that light appears to our eyes and how it spreads out over a surface, like how water spreads out on the ground after coming out of a hose.
So, even if one bulb gives off more light (lumens), if it spreads out over a larger area (lux), it might not seem as bright in one specific spot.
In your case, your 5000K bulb emits a lot of light overall (1100 lumens), and it seems really bright when you measure it with lux (24,530 lux). But your plant grow light, even though it emits less light overall (1690 lumens), might be more focused or placed further away, so it seems dimmer in the lux measurement.
To avoid harming your plants, consider factors like how close the light is to them and how long they're exposed to it. Even if a light seems really bright, if it's spread out or not very focused, it might not be as intense for your plants. So, watch out for signs of burning and adjust accordingly! Does that help? If not, I can explain it a few other ways for ya. Let me know - Charlie
@@ChristmasOnCrestline Thank you so much for answering my question. That makes absolute sense. You explain so well, you have a serious talent for articulating yourself and teaching! 🙏
@@humbleconfidence8844 Thank you so much for the kind words. It is appreciated!
What do you think about blue reduced led bulbs? I have bought Osram filament bulbs and I was surprised by the greenish light from them. I thought how is this cri 90+, and then I looked at the box and they're marked as blue reduced. I don't like the light at all.
I've heard of them. They are meant to be better for the eyes. As an example, the blue light from computers is harmful to our eyes. If you wear prescription glasses, your eye doctor has likely asked you if you wanted blue block on them. With that said, it would take some getting used to!
@@ChristmasOnCrestline about a year ago my oculist told me it's a trick to sell special glasses and blue light it's no more harmful than any other :) Anyway high cri means that the light is close in colors to the sun, right? Cri 90+ and it's yellow-green. It's surprising.
Good
Thank ya much!
I want a 100 watt dimmable adjustable kelvin to 10,000 that doesn’t hum have radio noise with Edison base with vibration resistance and shatter resistance .
Hello, V. I think you are asking me what the LED equivient would be to a 100w incandescent bulb. A 100w bulb is about 1,500 Lumens. Kelvin is the color temperature which would vary depending upon the brand and the model of the bulb.
Hey Charlie very informative video you got there. Got a question for you. I'm currently shopping for LED bulbs and I hesitate between the 60 watt or 100 watt. After watching this video it leads me to believe that I should ignore the 100 watt version because it would be nothing else but a waste in energy. Am I correct?
Hello there, Stephanie. The 60W has an estimated yearly cost of $7.23 and the 100W is estimated at $12.05. So, neither will break the back for energy cost. If I had to buy it again, I would just go with the 100W simply as it allows you the ability to bring it down to where you want it. Plus its 9000 lumen mark allows for a more cool white color. Hope that helps.
@@ChristmasOnCrestline I'm more inclined to go with warmer temperature bulbs so does that change your answer? And by the way I'm Stephane (male), not Stephanie! 😉
My light says 60w max does that mean only 60w bulb or can I use 8w lightbulb?
Sure! When a light fixture says "60W max," it means it can handle a light bulb with a maximum power of 60 watts. But you can use a bulb with less power, like an 8W bulb, without any problems. Think of it like this: the fixture is saying, "I can handle bulbs up to 60 watts, but I'll work just fine with a lower wattage bulb too." So, feel free to use your 8W lightbulb in that fixture-it's all good!

I'm So confused. My new flush mount ceiling light is OLD, but it is the only thing I can find to look good in a small space.
The Lamp asks for a 40 watt ligh tbulb. With the new LED, do I only need to consider the Lumins?
How do I know I won't over-power the socket and start a fire?
Thanks so very much!
Hey there, Mom. While I am not an electrician, the new LED bulbs have so little watts that I would not worry about a fire unless you have poor wiring or another reason to be concerned. Lumens will tell you how bright the bulb will be. As a means of conversion, a 40W bulb would be 300-500 lumens. Here is a conversion chart for you to see what I mean: www.any-lamp.com/lumen-to-watt/40-watt-in-lumens
@@ChristmasOnCrestline I could kiss you. You gave me the answer to the $64K Question.
Whew! Thanks so very much!!!!
@@momzilla9491 My pleasure, Mom. Seems like a conversion video may be of help to folks. I'll put that on my list of things to film later this year.

Thanks, Muhammad.
lumens=brightness overall so a flashlight so i can see the coyotes while I'm walking dogs i would need a high lumen high Kelvin for brightness because the more blue might be brighter, right?
Great question, LG. You just need the high lumens really. The Kelvin chart is to determine what color of white light you are getting. The lower the Kelvin, the more yellow it is. The higher Kelvin number, the more blue it will be. 5000 Kelvins is the mark where the white goes from a yellow hue and begins crossing into the blue color range. If you are an Amazon shopper, one of the filters (on the left side of the page) is the lumen count. For flashlights, I'm a Streamlight fan. Here is one of the flashlights I use, this is a 1000 lumens: amzn.to/474g4a3 This has two location for the power button and can clip on my belt or pocket for walks but it is small enough to go into your pocket as well. I hope this helps answer your question a bit more!
@@ChristmasOnCrestline thank you!!

Im still a bit confused. I went to buy a smart LED bulb that had a chart on the back that said 0 - 6000k. It was at '3000k soft light'. I need the daylight lighting and the guy said it can do 5600k no problem. Huh? I read the box and it says it can do up to 5000k so why is it marked 'soft light 3000k'? Ugh..
No worries, I've got you, Phat. It sounds like you're dealing with a confusing situation regarding the color temperature settings of your smart LED bulb. The Kelvin (K) rating on the bulb indicates the color temperature, with lower numbers (like 3000K) representing warmer, softer light and higher numbers (like 5600K) representing cooler, daylight-like light. If the box says the bulb can go up to 5000K, it means it can adjust to various color temperatures up to that limit, despite being currently set to 3000K. The "soft light 3000K" marking is likely the default setting, but you should be able to adjust it to your preferred daylight setting using the bulb’s app or controls. As this is a smart bulb, the app or controls should allow you to manually adjust the light's temperature. Many smart bulbs are like this.

3:43...(watts = power) != (energy = power*time)
Thanks!
What about the thousands of lumens that LED car bulbs promise with 20, 40, 60, 90 and 100 watts of consumption... for example, LED bulb with 100 watts and 40,000 lumens.
Is it a scam or is it true?
Thanks for your question! The lumens output claimed by some LED car headlights can indeed be confusing. While LEDs are generally more efficient than traditional bulbs, the relationship between watts and lumens can vary significantly based on the quality and design of the LED.
For LED car headlights, claims of very high lumens (like 40,000 lumens for a 100-watt bulb) should be approached with caution. Many manufacturers may exaggerate their claims to make their products appear more powerful. A more realistic output for high-quality LED headlights might be around 10,000-12,000 lumens for a 100-watt bulb. Here is an example of a typical 26W headlamp with 1800 lumens: www.autozone.com/electrical-and-lighting/fog-light/p/type-s-9005-9006-offroad-headlight/1070955_0_0
It's essential to look for reputable brands and products that have been tested and reviewed by third parties. Reliable manufacturers often provide detailed specifications and testing results, and products with certifications (such as from the DOT or ECE) are more likely to meet their claimed performance.
So, while some claims might be exaggerated, high-quality LED headlights can indeed offer significant brightness with relatively low wattage. Just be sure to verify the claims with trustworthy sources.
Hope this helps!
