God I worked at Home Depot for a few years and I remember having to explain to everyone that wanted to buy a lightbulb Kelvins/color temperature/cri/daylight vs soft white etc. and they always said the same thing “just gimmie a lightbulb”
Yep I feel you there. I worked at the electrical department at menards and had to explain these things to so many people and even after I explained it there was a lot of people that just didn't get it. I also had a lot of older people get mad that we didn't carry incandescents anymore and I tried to tell them why LED is so much better but they weren't having it.
NO! NO! NO! Many people say I am sick in the head. NOOOO!!!! I don't believe them. But there are so many people commenting this stuff on my videos, that I have 1% doubt. So I have to ask you right now: Do you think I am sick in the head? Thanks for helping, my dear rea

Funny thing: my art college was initially a typical college, so the bulbs were the long bright white fluorescent bulbs. When it became an art college, they were stuck with them. My teachers made it clear that the bulbs would make our paintings seemed washed out compared to incandescent bulbs and sunlight.
It's weird, but from a CRI perspective, somehow we got it right the first time with the janky old 1870s design incandescent bulbs, with their beautiful color fidelity. We're now able to achieve about 98 CRI with consumer-available LED lamps, but a lot of galleries still rely on halogen (which is incandescent but with a hotter, more compact design that provides some level of higher efficiency) to ensure the best possible viewing conditions for artwork.
@@nathaniellindner313 >somehow we got it right the first time with the janky old 1870s design incandescent bulbs, well, it's because it's a really "natural" process of just heating up a thing until it glows, hard to fuck that up
I know, this comment is old...... Still, as an artist myself, aside from me using only LED today, I always considered flourescent to be better for art, than incandescent. Because you just need to buy the right type of flourescent of pure daylight color and you are good. But incandescents are always kinda yellowish, naturally containing more red light, which makes all the warm colors in that spectrum hard to distinguish in drawings. It also made a big difference in what kind of light source a scanner used, I also mostly had this problem with warm colors there. Today all my artwork is digital, which takes the whole issue on the 21st century level. My digital drawings look different on all the different screens there are. My tablet is LCD, my main computer monitor is OLED. Drawings looking fine on the tablet are over saturated on the OLED, contrary when looking perfect on the OLED, they look too desaturated on LCDs......... Well, light is and will always be a central issue of all visual media. No surprise, I know.........
Red LEDs were commercialized in the 60s, but blue LEDs didn't become affordable till 30 years later (the man who did so got a nobel prize). This is why you don't see basically any blue seven-segment displays (think alarm clocks and cold-war era computers)
1993, so within most viewer's lifetimes. After that, the final big hurdle was white LEDs, which came out two years later. They started showing up in holiday lights by the late 90s, apparently their first big use as home lighting (of a sort).

Your channel is chef's kiss. One of my favorite bits is discovering what you find interesting enough to create content around. The range is astounding.
To add onto what could come next after LEDs, one thing that you didn't mention in the video was one of the craziest potential things we could get if we switch to laser-based lighting: Centralized lighting systems. Instead of every room in your house having it's own lightbulb, you could have one big lightbulb in your basement whose light could then be beamed to any part of your house using a system of pipelines and mirrors throughout the building. Turning on light would be simply opening a pipeline to said location and increasing the luminosity of the central bulb proportionally for it. It's just like having centralized heating with a boiler and radiators, but for light.
That sounds overly complicated. We already have wires in all homes, why add an extra layer of mice food? What if you want a different color temperature, or a different color? What if it's an apartment building? What about all the people using lamps? Do you add "light sockets" in the house? Sounds fancy, but it's not really practical.
This sounds like the hyperloop of lighting. It's cool sounding but as soon as you start to think about it for more than a second you realize how impractical and inefficient it would be

First time I've EVER seen a lightbulb advert on youtube (as an adroll) was on your video. Its good to know that there are more than door dash adverts on here.
I still use incandescent bulbs in the lamp on my night stand. I also have nostalgia for all the wacky things that florescent bulbs do. The buzzing and the flickering and the slow start up and the bad colors. It really fills a place in my heart.
Hey Tyler, just wanted to say that this is probably my favorite video of yours. I dont know why, but I've watched it like several times over the past year. Video idea: the history of advertising. And in a similar retrospective way as this video. Or however you wanna do it. But i think it would be a great topic for you to cover in your style. It could touch on how consumer goods even became a "thing" at the end of the 1800s, and how simple advertisements started out, like "buy ___, it's the best". And how the general trends shifted over the decades to outcompete the then-stale market, all the way to gnar-tacular 90s/00s, to the sincere/ironic/awkward 2010s and beyond. I think it'd be pretty neat.
This is a cool video. I'm a total nerd and want point out that LED's are single color only. If you ever purchase an LED that can change colors, it's actually made of 3 small LEDs for Red, Green, and Blue. You still have to address each individual diode. RBG LEDs that are sold in electronics kits for instance are marketed and packaged in a way that make it seem like it's a single unit, but it's not.
i've noticed that there has been an influx of news stories about lightbulbs in the last few weeks. some were even posted by national news outlets. though the coincidence is odd, this is by far the best one. i love this channel no matter where it goes, but it pleases me you tackled a subject a bunch of other people just tackled but did it best. it's not even close how much more informative this was over the others. also, WAY more entertaining.
Every time a light bulb burns out and I have to replace it, I'm reminded of that firehouse that's had the same light on for over 100 years and suddenly I'm mad at lightbulb companies all over again
You did an awesome job with this man, very well done. Jsuk the buzzing you said that fluorescent lamps give off is actually from the ballast of the in the tube form of the fluorescent lamps. In order to get the lamp to start the gases inside need a higher amount amps to ignigite the gases and then a why they flicker. The screw in Lamps have a built in miniature on in the base that doesn't give off the same amount of noise. - Electrician
Man I understand the obsession with lightbulbs. Was on vacation this week doing some bedroom remodeling. Discovered GE WiFi smart multi color lightbulbs and how to voice link them to Amazon Alexa. Let’s just say I bought 30+ bulbs and redid all the light fixtures in my house on top of buying a Amazon Alexa for every room to totally voice control the lighting in my house... it’s.. Amazon.. I mean amazing.
So most LED light bulbs are designed to run the LEDs much harder than necessary. This tends to produce just enough heat to eventually fry the electronics inside the bulb. Sure, the bulbs COULD last forever... Given their past record, I don't think it would make you a cynic to think that they do this on purpose.
Honestly I love how much light an LED can put off for 3-4 bucks as it really helps int he Winter with depressiong due to a lack of light in general (older technologies just didn't put off enough light unless you put like a 2000 watt bulb in a socket)
Technology Connections did a vid on the whole "light-bulb conspiracy". It's complicated, but to try and summarize, it was less about planned obsolescence, and more about industry standardization. Incandescent bulbs had a specific case of the production triangle: it was a tradeoff between brightness, electricity consumption, and lifespan, and the consortium defined the "sweet spot" that everyone had to adhere to. Sure, it was possible to get much higher lifespans out of them, but it was at the expense of brightness and, counter-intuitively, power consumption. Long story short, bulbs in the "sweet spot" consumed 1.0 unit of electricity to produce 1.0 level of brightness over 1.0 lifespan. It was possible to double the lifespan by cutting down the power, but the relation wasn't linear, so you got a light bulb with 0.8 consumption, 0.5 brightness, and 2.0 lifespan. So, in order to have the same brightness as before, you had to buy a bulb of a higher wattage, resulting in 1.6 power consumption, 1.0 brightness, and 2.0 lifespan... meaning you ended up with a net higher power draw, which cost you more money on the long run than just replacing the original light-bulb once it burned out. In other words, the consortium was a conspiracy, and they did engage in shady monopolistic stuff like price-fixing, but the standardized incandescent bulbs they created were, in fact, for the benefit of the consumer. As Alec put it, the world is complex, and you should be skeptical of simple narratives.
This video made me very happy that I became a patreon supporter. I already knew a good chunk of it, but the presentation never disappoints, and I learned a few things.
It's honestly news to me that CFLs never took off because they got pretty big here in Trinidad and we still have a few at my house. My dad was big on them. But we've mostly switched to LED now. It's just so much better.
When California got rid of traditional bulbs I stockpiled the old ones. Not because I related the new ones with work or color temperature (although sometimes they give me headaches) but because the porch light in my ye olden apartment has a ye olde timer attached that won’t work with new bulbs. Since the landlord won’t swap it’s either find old bulbs or be in the dark!
I doubt lasers will replace light bulbs around the home anytime soon. Laser headlights on cars are great because aiming light in front of the car with mirrors as we've traditionally done is a bit of a shotgun approach and requires all the space needed to focus a beam of light with mirrors. Lasers are directional and can be aimed with a prism so they take up less space and can be laser-focused (haha) on where the car is pointed without illuminating everything else and creating light pollution. In the home, I might want to focus light on my desk, but I usually don't want the rest of the room to be dark so I'm okay with light bleed from my lamp. Space isn't at a premium in the home like it is in a cramped engine bay so fancy lamps are fine, I guess.
Nice. I love the genuine passion for an odd, niche thing really shines though. The script roles easily because this is obviously something you've actually spent some time thinking about, and not a script you wrote because it was time for a new video. Great work.
I loved this video, than you. :) A few things though: The mercury in fluorescent lamps is not a lethal amount, if you bust one just open a window and leave the room for a few hours and it will safely dissipate. Cheap bulbs lead to pretty bad stigmas, that why you see those older cfl and leds lamps go for ages while the newer one are cheaper but have a much higher failure rate Electronic ballasts solved that flicker issue by driving the tubes at tens of thousands of hertz, allowing the phosphor to not decay before more uv is available to pump them again. Old magnetic gear had this issue because it still ran the tubes at 60Hz. That led that was flickering was because of a bad electronic driver, not the frequency of the household current. Failing fluorescent bulbs on preheat circuit tended to blink a lot as the starter would try and start the lamp but it would not work and tyr to start it again Bulb bans are mixed bag for me because i like having the consumer choice and am willing to pay more for electricity with them, not being forced to use one thing by a government and instead let a slow transition take place. I use halogen tec because its legal to by in my state and just as good as incans, but they sorta lie in the fact that a 60w lamp is 800 lumens standard and those 43w halogens are 620-630ish to skirt into the 60w equivalent categories, they are still more efficient. A dimmer running an incan at 80% brightness make it use less power and can extend its life a few fold. Lasers are leds but on steroids and hyper focused, they still use the same diode tech just kicked up a notch or two. Well that's my info i have in my brain, if anyone collects bulbs like me or wants fore info, lighting-gallery.net is a pretty good place to ask questions and get some info from a few people more knowledgeable than i am.
I have some of those cool LED ones that you can change the color on. In my bedroom it's more yellow because when I was growing up, we had those yellow ones that got really hot and it reminds me of home. :)
I knew about Lumens because I used it as a unit of measurement for a Science Fair project about stealth aircraft coatings in junior high. Made me feel like a smart cookie.
At 15:38 you say we could have lights where you can change where the light goes. You can already do that, thats how theatrical and event lightings works. They use a combination of lenses in a tube to zoom and focus the beam of light onto a specific area.
that LED bulb you have going bad is probably going bad because you have it in an enclosed fixture, LEDs are sensitive to temperature and can fail when they get too hot, you should check if the bulb is rated for enclosed fixtures or if it's depending on airflow for its cooling. more expensive bulbs actually have logic to lower their brightness when they start heating up to mitigate the issue, definitely a "you get what you pay for" situation.
I remember seeing an add in a Popular Science magazine from 2012 that had an LED bulb for $40 each from Walmart, and my only thought was “This thing must be pretty special if marketing thinks people will consider that price worth it.” Shockingly enough, I was right.
Your LDS are flickering because you have them on a closed lamp with no ventilation. Even if the led itself doesn't heat up, the circuitry does, which isn't a problem with a little ventilation, but that lamp cover impedes that
The problem with led lights is the circuitry to step down the voltage for the leds. It has a lower life span than the actual leds. For high-end led bulbs, like in offices, this part can be replaced to prevent wasting the still good leds. It cant / wont be done for consumer bulbs tho...
Last Christmas our lights were a more blueish white compared to our usual yellow. Took me some time to get used to because it was descripted as a cold white and I felt colder even though it's 7000 - 8000 K.
Translucid area of a normal LED bulb is considerably lower than the one from a incandescent bulb. What I mean to say is only giving light on the upper side of that sphere so sometimes is bad at distribution of light in all corners of a room
The laser die is more efficient at producing light over an LED die, but they still use that light to pump phosphors. So yes when you say lasers could be the future you are correct. However there is no advantage over LED or any other light when it comes to intensity distribution. The ability to precisely scan, move, or change the intensity distribution in a non traditional manor comes from the ability to steer the laser beam. Beam steering uses a composite RBG laser system for white, which while it does give you exact control over intensity distribution have by nature a terrible CRI since it's just 3 wavelengths. You're not getting high CRI finely adjustable intensity distribution laser lighting, physics says " no ".
I'm really enjoying this video, actually. I hope you make more like this--so long as you actualy like to. Please don't let the viewer-count discourage you.
The planned obsolescence of old bulbs was only partly about making money. At the time, the longer lasting bulbs were much dimmer than the bulbs that burned out fast. Consumers didn't care that they had to replace the bulbs more often because they were much brighter
The fact I actually learned something and was actively interested in this absolute fever dream speaks volumes to your talent

It could touch on how consumer goods even became a "thing" at the end of the 1800s, and how simple advertisements started out, like "buy ___, it's the best". And how the general trends shifted over the decades to outcompete the then-stale market, all the way to gnar-tacular 90s/00s, to the sincere/ironic/awkward 2010s and beyond.
I think it'd be pretty neat.
i really like the jazz music in this video for some reason
This is a cool video. I'm a total nerd and want point out that LED's are single color only. If you ever purchase an LED that can change colors, it's actually made of 3 small LEDs for Red, Green, and Blue. You still have to address each individual diode. RBG LEDs that are sold in electronics kits for instance are marketed and packaged in a way that make it seem like it's a single unit, but it's not.
This talk about lighting brings me back to film school.
i've noticed that there has been an influx of news stories about lightbulbs in the last few weeks. some were even posted by national news outlets. though the coincidence is odd, this is by far the best one. i love this channel no matter where it goes, but it pleases me you tackled a subject a bunch of other people just tackled but did it best. it's not even close how much more informative this was over the others. also, WAY more entertaining.
Jomama is a lightbulb.
A return and an improvement, the old with the new, i love it
Thanks KnowledgeHub for the history of light bulbs, I like having warm colour temperature light bulbs in lamps it's easy on the eyes.
The sound quality is much better now. Thank you Mr.Hub
after seeing so many lightbulbs, it feels like they don't even exist.
Every time a light bulb burns out and I have to replace it, I'm reminded of that firehouse that's had the same light on for over 100 years and suddenly I'm mad at lightbulb companies all over again
You did an awesome job with this man, very well done. Jsuk the buzzing you said that fluorescent lamps give off is actually from the ballast of the in the tube form of the fluorescent lamps. In order to get the lamp to start the gases inside need a higher amount amps to ignigite the gases and then a why they flicker. The screw in Lamps have a built in miniature on in the base that doesn't give off the same amount of noise. - Electrician

I love your explanation of black body radiation
This is like one of my favourite RUclips channels.
Man I understand the obsession with lightbulbs. Was on vacation this week doing some bedroom remodeling. Discovered GE WiFi smart multi color lightbulbs and how to voice link them to Amazon Alexa.
Let’s just say I bought 30+ bulbs and redid all the light fixtures in my house on top of buying a Amazon Alexa for every room to totally voice control the lighting in my house... it’s.. Amazon.. I mean amazing.
So most LED light bulbs are designed to run the LEDs much harder than necessary. This tends to produce just enough heat to eventually fry the electronics inside the bulb. Sure, the bulbs COULD last forever... Given their past record, I don't think it would make you a cynic to think that they do this on purpose.
The mundane nature of this topic was refreshing within the context of this channel.
Honestly I love how much light an LED can put off for 3-4 bucks as it really helps int he Winter with depressiong due to a lack of light in general (older technologies just didn't put off enough light unless you put like a 2000 watt bulb in a socket)
Technology Connections did a vid on the whole "light-bulb conspiracy". It's complicated, but to try and summarize, it was less about planned obsolescence, and more about industry standardization. Incandescent bulbs had a specific case of the production triangle: it was a tradeoff between brightness, electricity consumption, and lifespan, and the consortium defined the "sweet spot" that everyone had to adhere to. Sure, it was possible to get much higher lifespans out of them, but it was at the expense of brightness and, counter-intuitively, power consumption.
Long story short, bulbs in the "sweet spot" consumed 1.0 unit of electricity to produce 1.0 level of brightness over 1.0 lifespan. It was possible to double the lifespan by cutting down the power, but the relation wasn't linear, so you got a light bulb with 0.8 consumption, 0.5 brightness, and 2.0 lifespan. So, in order to have the same brightness as before, you had to buy a bulb of a higher wattage, resulting in 1.6 power consumption, 1.0 brightness, and 2.0 lifespan... meaning you ended up with a net higher power draw, which cost you more money on the long run than just replacing the original light-bulb once it burned out.
In other words, the consortium was a conspiracy, and they did engage in shady monopolistic stuff like price-fixing, but the standardized incandescent bulbs they created were, in fact, for the benefit of the consumer. As Alec put it, the world is complex, and you should be skeptical of simple narratives.
This video made me very happy that I became a patreon supporter. I already knew a good chunk of it, but the presentation never disappoints, and I learned a few things.
The world is a much better place with you in it. thanks for the videos!!
I love this channel and I want a light ups that last forever
At this point you and Technology Connections should team up
It's honestly news to me that CFLs never took off because they got pretty big here in Trinidad and we still have a few at my house. My dad was big on them. But we've mostly switched to LED now. It's just so much better.
wow, a video not about video games, but with tylers new style on it. I like it.
When California got rid of traditional bulbs I stockpiled the old ones. Not because I related the new ones with work or color temperature (although sometimes they give me headaches) but because the porch light in my ye olden apartment has a ye olde timer attached that won’t work with new bulbs. Since the landlord won’t swap it’s either find old bulbs or be in the dark!
Thank you, Uncle Tyler, for returning to semi-sanity even if it's just for one video. We love you dude.
I doubt lasers will replace light bulbs around the home anytime soon.
Laser headlights on cars are great because aiming light in front of the car with mirrors as we've traditionally done is a bit of a shotgun approach and requires all the space needed to focus a beam of light with mirrors.
Lasers are directional and can be aimed with a prism so they take up less space and can be laser-focused (haha) on where the car is pointed without illuminating everything else and creating light pollution.
In the home, I might want to focus light on my desk, but I usually don't want the rest of the room to be dark so I'm okay with light bleed from my lamp. Space isn't at a premium in the home like it is in a cramped engine bay so fancy lamps are fine, I guess.
Nice. I love the genuine passion for an odd, niche thing really shines though. The script roles easily because this is obviously something you've actually spent some time thinking about, and not a script you wrote because it was time for a new video. Great work.
Knowledge returns to the hub, and all and sundry rejoiced.
Without the invention of the light bulb we wouldn’t have Knowledge Hub
Let that sink in
Glad you’re on the rode to one million subs dude
I loved this video, than you. :)
A few things though:
The mercury in fluorescent lamps is not a lethal amount, if you bust one just open a window and leave the room for a few hours and it will safely dissipate.
Cheap bulbs lead to pretty bad stigmas, that why you see those older cfl and leds lamps go for ages while the newer one are cheaper but have a much higher failure rate
Electronic ballasts solved that flicker issue by driving the tubes at tens of thousands of hertz, allowing the phosphor to not decay before more uv is available to pump them again. Old magnetic gear had this issue because it still ran the tubes at 60Hz. That led that was flickering was because of a bad electronic driver, not the frequency of the household current. Failing fluorescent bulbs on preheat circuit tended to blink a lot as the starter would try and start the lamp but it would not work and tyr to start it again
Bulb bans are mixed bag for me because i like having the consumer choice and am willing to pay more for electricity with them, not being forced to use one thing by a government and instead let a slow transition take place. I use halogen tec because its legal to by in my state and just as good as incans, but they sorta lie in the fact that a 60w lamp is 800 lumens standard and those 43w halogens are 620-630ish to skirt into the 60w equivalent categories, they are still more efficient. A dimmer running an incan at 80% brightness make it use less power and can extend its life a few fold.
Lasers are leds but on steroids and hyper focused, they still use the same diode tech just kicked up a notch or two.
Well that's my info i have in my brain, if anyone collects bulbs like me or wants fore info, lighting-gallery.net is a pretty good place to ask questions and get some info from a few people more knowledgeable than i am.
I have some of those cool LED ones that you can change the color on. In my bedroom it's more yellow because when I was growing up, we had those yellow ones that got really hot and it reminds me of home. :)
One of the last college essays I wrote was about lightbulbs, so finding this in my subscriptions was a surprise XD
I knew about Lumens because I used it as a unit of measurement for a Science Fair project about stealth aircraft coatings in junior high. Made me feel like a smart cookie.
This video gives me heavy Technology Connections vibes
At 15:38 you say we could have lights where you can change where the light goes. You can already do that, thats how theatrical and event lightings works. They use a combination of lenses in a tube to zoom and focus the beam of light onto a specific area.
that LED bulb you have going bad is probably going bad because you have it in an enclosed fixture, LEDs are sensitive to temperature and can fail when they get too hot, you should check if the bulb is rated for enclosed fixtures or if it's depending on airflow for its cooling. more expensive bulbs actually have logic to lower their brightness when they start heating up to mitigate the issue, definitely a "you get what you pay for" situation.
That goddam dinosaur is so cool
This guy's seriously gonna go from talking about videogames for years to being a goddamn electrical channel.
Keep it up!
Filled my room and basement with color changing LED light bulbs. Much fun.
THIS IS IT
I HAVE BEEN SEARCHING FOR THIS VIDEO FOR YEARS
YES!!!
Beautiful. Informational and quirky. I love it.
The content and subject that I have always yearned for!
I remember seeing an add in a Popular Science magazine from 2012 that had an LED bulb for $40 each from Walmart, and my only thought was “This thing must be pretty special if marketing thinks people will consider that price worth it.” Shockingly enough, I was right.
Your LDS are flickering because you have them on a closed lamp with no ventilation. Even if the led itself doesn't heat up, the circuitry does, which isn't a problem with a little ventilation, but that lamp cover impedes that
Never thought I'd see the words Illumination and perfection in the same sentence.
This video deserves wayyy more views.
First video that’s not an acid trip, nice.
The problem with led lights is the circuitry to step down the voltage for the leds. It has a lower life span than the actual leds. For high-end led bulbs, like in offices, this part can be replaced to prevent wasting the still good leds. It cant / wont be done for consumer bulbs tho...
bruh this channel is so underrated
oh hey look it’s KnowledgeHub with a new video
Hey
The Communist Pretzel hey
Oh hey its a Hub with a new knowledge
Last Christmas our lights were a more blueish white compared to our usual yellow. Took me some time to get used to because it was descripted as a cold white and I felt colder even though it's 7000 - 8000 K.
Who woulda thought that the lightbulb episode would be way less flashy, and way more sane?
Translucid area of a normal LED bulb is considerably lower than the one from a incandescent bulb. What I mean to say is only giving light on the upper side of that sphere so sometimes is bad at distribution of light in all corners of a room
The laser die is more efficient at producing light over an LED die, but they still use that light to pump phosphors. So yes when you say lasers could be the future you are correct. However there is no advantage over LED or any other light when it comes to intensity distribution. The ability to precisely scan, move, or change the intensity distribution in a non traditional manor comes from the ability to steer the laser beam. Beam steering uses a composite RBG laser system for white, which while it does give you exact control over intensity distribution have by nature a terrible CRI since it's just 3 wavelengths. You're not getting high CRI finely adjustable intensity distribution laser lighting, physics says " no ".
I'm really enjoying this video, actually. I hope you make more like this--so long as you actualy like to. Please don't let the viewer-count discourage you.
Nice advanced pun there at the end!
The planned obsolescence of old bulbs was only partly about making money. At the time, the longer lasting bulbs were much dimmer than the bulbs that burned out fast. Consumers didn't care that they had to replace the bulbs more often because they were much brighter
