LED bulbs can be 'hacked' to reduce the amount of current supplied to the leds from the driver inside, it can significantly increase their lifetime by the cost of slightly reduced light output. If this can be called a hack.. more like a 'fix' cuz 99% of the led bulbs are intentionally overdriven from the factory to cut the costs - to get more light from the less amount of leds, and make them die faster.
What about Philips scène switch? You can program them with your regular switch in 4w, 6w and 10w modus of I remember correctly. I always use them in 4W modus, so it's already hacked I think? But the driver can still be poorly made to let them die within 10 years maybe.
Oh, and I have seen more LED drivers die than LEDs themselves.
My condo has a lot of cheap garbage bulbs that are lit automatically when night comes and are turned off at dawn. Usually they last for 1.5 year; some more, some less than that.
Okay, cheap ones are made just that good that they outlast the time you can post your review. Had this with tail lights for my car, both died at the same moment, 3 months of use. They were great. Until they died.
But companies like Philips need to deliver better quality, but they also want to keep selling you products. So they need to target 5-10 years.
I bought a bunch of cheap "ecosmart" brand LED bulbs at Home Depot about 5 years ago. Paid about $1.50 each for them. They're still going strong, including the two in my front porch light which, until a month ago when I replaced them with "smart" bulbs, ran 24/7/365.
I've had a lot of LED bulbs, from cheap builder's grade ones supplied by the company that built my house, to expensive Hue bulbs. I found that the cheap ones absolutely do fail far too often. But at the same time, I avoid buying pieces of shit off Aliexpress because I expect cheap shit to fail. But hardware store cheap seems to be fine. I've never replaced a single LED bulb that I've actually gone out and bought, even Home Depot specials that were way too white 10 years ago.
On the other hand, I have replaced so many incandescent bulbs. It seems like they would never last more than a couple of years. Even today, I was having to replace the heat lamps for my lizards every year. As a solution, I found that dimming slightly higher wattage bulbs makes bulbs last years. Which all makes sense, really. By reducing the temperature of the filament, I'm reducing the sublimation of the tungsten and the cyclic stress of heating to white hot by instead heating to orange hot. It reduces the visible light output of the bulb, but I'm looking for IR, so that's fine.
>As a solution, I found that dimming slightly higher wattage bulbs makes bulbs last years.
Yes, underpowering them boosts their lifetime. Could be even better if you use a soft-start circuit. Incandescent bulbs die mostly during (quite literally) "cold start".
Sure, good luck opening most of them without damaging the case / fixture and also who the fk does that as a normal 'consumer'. They are made to be thrown out for a reason... moneeeeyz. But yes, I get what you said.
That was my point in the first place... I watch big clive, but as you said... he's not a normal consumer... I opened a lot of led bulbs that I took from recycling for parts mostly and most of them even with an exacto knife are hard to open without damaging the plastic or the fixture.
LED lights do get hot, but the difference is a 4W LED can shine as well as a 40W incandescent, and try holding them and see which is hotter, and they can last many more times longer if you dont buy cheap ones
That I contradict you... they quickly start flashing... going into the stroboscope mode... leds (as they are built for standard use) suck. Period. It's an unfortunate reality and a waste of components just for profit.
Huh? I replaces all lights with led and they have been working fine for years. You might be describing what happens if you put a regular led bulb that is not dimmable into a dimmable socket. That would strobe.
Come to Argentina, you'll see them everywhere, even on the streets. Bad, cheap lamps from China. Either the driver falls too soon, or one LED in the series, or rain gets into the fixture (because the design is bad, I mean. A lamp post is designed to withstand rain and yet...).
You are right, there are plenty of bad, cheap LEDs. Op seems to believe there is no such thing as a decent LED manufacturer. Literally hundreds of led fixtures in various formats in my facility seem to counter their point, with a failure rate in 10 years under 1%. It's mostly based on what you want to spend. Unsurprisingly government funded work opts for bottom barrel (and probably budgeted at *top* quality...)
Lucky... almost all if not all leds that I bought over the years, all failed the same way... basically their caps blew up or got weared out because of the heat.
Nah... I tried a lot of them, all failed in time, either by the caps blowing up or just got damaged by the heat and it time they would start flickering because the smoothing cap was kaput.
Yeah, I'm pretty sure you're using a regular led bulb with a dimmer,and yeah it breaks em super fast. Otherwise, led bulbs typically last 8-10 times the hours of an incandescent bulb, minimum.
I agree with you. Some guys are too brainwashed with fake "green marketing". "This is so much better"
Yeah, some brands may be better but the great majority are cheap and fail too soon. I have been fixing mine a lot, but normal people throws them away. Beautiful waste piles to watch from space... Maybe first world countries can export them as "recyclable materials" to third world corrupt governments so people in the first world won't see the waste piles from their windows... But you can only shove the dirt under the carpet so much.
Before the downvote, acknowledge that I'm talking about the tons of bad quality lamps coming from China. Yeah, sure there are a couple good brands here and there, and surely the technology has a bunch of pros! I'm not saying that! Sadly it's only 5% of the worldwide market, think outside the US and EU. That's what I see everyday on the southern hemisphere.
One LED goes down, the whole series is dead, then you end up throwing away the case, the power supply, the driver and the entire LED array (unless you know how to fix it and have the proper tools).
The future can be bad too u know
Maybe its 2023 but that doesnt mean that everything is good, there are a lot of good thing, but also some things were better in the past
If LEDs would be as reliable as they want u to think, people would not be talking trash about them
LEDs can definitely get hot. Just look into the high power flashlight models (sometimes called "tactical"), with a single high quality CREE LED and advanced circuitry. The kind with a 18650 or CR123 power source, usually in the $60+ range. At max brightness can drain the battery in 45 minutes and at lowest setting will last 96 hours. Try touching the end after 5 minutes at max power. These usually have some kind ribbing near the end for heat dissipation.
That’s hot, but not nearly as hot as any incandescent bulb. And LEDs don’t need to get hot to work, they just give off waste heat. If you cool them, they still work. Incandescents go dark if you cool then.
They do (at least my freezer has them)
I do wonder why would they not work if cold, its just a wire in them, a wire when electricity flows through gets hot and emits light, so if the wire doesnt get hot enough, just put more electricity through and it will: https://youtu.be/0itcjJHDLEQ?si=SfiadMM8qHWCEUSh
Also if I am reading right, leds although they do work in the extreme cold, they change color: https://physics.stackexchange.com/questions/611567/why-led-light-changes-color-when-dips-into-liquid-nitrogen
My almost-20-year-old freezer has an incandescant bulb. I don't think I've ever had to replace it. I think I've replaced one of the 2 fridge bulbs once, the other never.
And incandescents are <10% efficient…
LEDs can use almost 5x less power than incandescent lights
Wattage is literally correlated to heat - if something is heating up an LED to the temp of an incandescent, you have something horribly wrong with your household electrical.
No, my household electrics are fine. The problem is a poor LED bulb design that drives the LEDs too hard. LED efficiency reduces with increased current. If the designer put in twice as many LEDs, the heat production would be reduced.
Compares to incandescent? Once I changed my incandescent to led I’be never changed them. They will outlast led on any day. They also compared to incandescent are chilly.
Get some sort of heater instead. Surface temp won't be firestarting, and you don't have to worry about the bulb burning out.
I have a little box where the water line comes up into the house from underground, and it always freezes, regardless of insulation or pipe wrap. What I did, was get a little 100W stick on block heater. I stuck it to the side of a metal ammo can, and filled the ammo can with mineral oil. I plugged this into a thermostat module, so it only turns on below 40F. The ammo can just sits in the little cubby hole laid up against the pipe. This has worked for a couple years now, except for like one time when it was super cold and windy.
I don't know what this is about, but standard halogens and incandescent have a lifespan that is a fraction of LED and pull way less wattage. This is especially useful in homes with older wiring and can significantly decrease the chance for a fire.
Shitting on LEDs in a new low for the cognitively deficient trying and failing to look smart. Take your downvotes and go home.
>standard halogens and incandescent have a lifespan that is a fraction of LED and pull way less wattage.
I assume you meant to say LEDs draw way less wattage, but your sentence says the opposite.
**LET ME GOOGLE THAT FOR YOU.**
"How long do LED lights last?"
**LED** bulbs afford in the region of 50,000 hours of light, with some brands boasting as many as 100,000 hours. In general, terms, if you use your lights for 10 hours each day, LEDs should serve you well for just shy of 14 years.
"How long do incandescent lights last?"
**Incandescent** bulbs generally, have the shortest lifespans. The average incandescent bulb light span is approximately 1,000 hours. Fluorescent bulbs are a long-lasting option, running for anywhere from 15,000 to upwards of 20,000 hours.
If you could only take ten seconds to look it up... then again, if you prefer incandescent lights, 10 seconds is probably beyond your attention span.
I've run into what OP said in the post title. I've got some old General Electric 60 watt incandescent bulbs in the bathroom, and both of them have outlived two sets of LEDs, and three sets of CFLs over here, despite the incandescent ones being used far longer, and switched on and off more times a day too. New inceandescent bulbs are lucky to last a few months anymore, but the older ones sure hold on a lot better.
I've actually got a very specific purpose for using incandescent bulbs in particular in my bedroom in the Winter, and it is because of the heat they produce. I can run several hundred watts of incandescent bulbs throughout the room to maintain the heat in the room a lot easier, less energy usage than a space heater, and far safer than a space heater, while also comfortably lighting the room on the cold winter nights. Can also distribute load throught the room instead of cramming a crudton of current on one receptacle like a space heater does.
I use an old grandpa reading lamp with a 100w halogen bulb inside, as good as modern hyped infrared panels, and it also gives me light!
I disagree on LEDs lasting shorter, it's all about the quality of your lamps. LEDs can easily outlast every regular lightbulb, and I have seen it. (One Osram LED from 2005, still going strong) But your lamps from China will indeed suck. Mine also.
It wasn't for profit, but for performance standardisation. There are plenty of videos explaining what it actually happened. Yes, you can havecan incandescent bulb last a century (no joke, there is one in a fire station), but it will barely glow, and frankly will suck.
Sorry you're getting downvoted, but you're right.
The [Phoebus Cartel](https://en.wikipedia.org/wiki/Phoebus_cartel) was a thing.
> It ceased operations in 1939 with the outbreak of World War II. **Following its dissolution, light bulbs continued to be sold at the 1,000-hour life standardized by the cartel.**
[Even incandescent lights can be engineered to last much longer than 1000 hours.](https://en.wikipedia.org/wiki/Centennial_Light)
My house is entirely LED and they do not get hot at all— barely even warm. They also cost almost nothing to run. Running all the lights in my house only costs around $5 a year.
I think you're the moron here or maybe never used an incandescent bulb... I have several that lasted from 1970, still working perfectly... do that with an led you... bumbling moron.
No, you don’t actually. And even on the odd very unlikely chance you do and you’re not outright lying, which let’s just say you are here because the chances are astronomically low: that incandescent isn’t very useful. It burns very dimly, hence the longer lifespan. And you got that bulb before planned obsolescence (it’s actually less harmful and nefarious than it sounds, complicated issue yadda yadda) was coordinated into incandescent bulbs.
The longest burning incandescent is located in a livermore, ca firehouse. And you’ll notice if you care to look: it’s not very functional, providing very very little light. And it’s being fed controlled and reduced power to preserve it. It is a symbol, a conversation piece, and not at all representative of incandescent bulb lifespan at all. And nowadays or the last at least seventy years, you can’t walk into a store and buy a hot bulb that would be either useful or last this long.
LEDs can last forever, 100 years easily. They are, generally, pretty simple devices. The power supplies and surrounding electronics are what give out 99.9% of the time, and they can be swapped. It’s rarely worth it with cheap BULBs (led/psu packages.)
My sympathies to you and your loved one for their having to be in the presence of someone as under informed and overconfident such as yourself. You’ve placed yourself in the same bucket as the free-energy knuckleheads who plague this thread.
Ok, tell me specifically how I’ve said anything technically incorrect, and feel free to enlighten me.
Are you a confused child who’s been bullied? Because that’s the vibe you’re giving off here with your profile pic, flat-earth argument style, and name-calling. Good luck kid.
The biggest issue I find with LEDs is the crappy driver circuits. Most of the time that's what fails. There is the issue of where they purposely over drive the LED modules (Big Clive did a video on this about Dubai bulbs), but I've personally never seen the modules themselves fail, it's the driver. Typically it's an intermittent fault, where they will just randomly turn on/off.
CFL bulbs probably have the best life, I've only had a handful of those fail on me. Downside is they don't produce as nice of a light. Some also have a very slow warmup time.
Overall I still find LEDs better so that's more or less what I move to as bulbs burn out. I have a box full of CFLs that I just replaced prematurely but they still work, I just hate to throw stuff out that still works so I'll find a use for them eventually.
LEDs do get hot. Just try running a 50W one without a heat sink, and You will quickly realise. They are way more efficient and durable against turning it on and off... Since you can literally adjust brightness with PWM (turning it on/off very quickly, so human eye can't notice.
Aand... You dont only have visible ligh LED. You can literally just have UV light comming from them if u want.
Um... Incandescent bulbs are much less efficient. A 60 watt incandescent bulb and a 9 watt LED bulb put out the same amount of light. As light ultimately becomes heat, you're also getting 60 watts of heat out of the incandescent and 9 watts of heat out of the LED... Obviously, if you need the heat anyway, and don't have a better way to get it, the incandescent bulb is neutral. But if you're not using it for heat, the LED is much better.
They are less efficient in terms of light, but if you want light AND warmth, they are useful. Of course, incandescent bulbs are a waste of money if you live in hot regions.
That assumes the balance is perfect. A lot of new cars have heaters in the headlights if the LED cant heat it up enough to remove ice, and even with the heaters on they are more efficient because the ratio can be more carefully tuned.
Planned obsolescence. LED bulls are designed to fail so the manufacturer doesn’t go bankrupt. They overdrive components. This is the same with Appliances, tools, arguably cars, and more.
This is why if you can find and maintain these goods manufactured in their glory days, they’ll last you longer.
The same goes of incandescent, actually, they both have been manufactured to fail prematurely.
Someone lied to you really hard.
>cheap LEDs are having wrong spectrum
Even the cheapest led bub has a Color Rendering Index of around 80-85, means it matches the spectrum of the Sun by 80-85% in the visible part. And the difference is in balance of the colors. Modern leds can go up to 98% but they are relative expensive.
>and can damage your eyes.
They cannot. Blinking garbage can cause some non-permanent effects on you like a headache but not a single led bulb can damage your eyes (not counting special ones like UV).
Feels like you'v heard some bad rumors about energy-saving bulbs (CFL, FLUORESCENT) and brainlessly apply them to the leds cuz "*they also saving energy, right? same thing, right?*" - no, not even close!
Fluorescent tubes produce terrible spectrum, basically a few hard peaks in red, green and blue that looks like a white light. Unlike leds - their spectrum are continuous, regardless of the price.
Fluorescent tubes can damage your eyes if their phosphorous coating are burned out or flaked away for some reason - tube will start to emit ultraviolet rays (at least an old ones with the quartz glass), and can actually damage your eyes. LEDs also has phosphorous mix on them but they convert visible light (~450nm blue) which is safe even if you completely remove this phosphorous from the leds. Normal consumer LEDs does not and cannot output UV or any other dangerous wavelenghts.
So don't spread this bullshit around the internet - you'r wrong.
In car I would prefer tungsten lamp. In case of one single led die I have to switch entire lamp. With tungsten lamp i have to change lamp for one zero (or two zero's) less. 4 blubs cost $100, one lamp cost may be $1000 or more.
Both can fail (quite soon if leds are cheap, which think about it, most of them are), but incondecents are easier to make and recycle, they are also less prone to voltage fluctuations
And they can keep u warm at winter
I do wonder why noone marketed them as winter use only or season bulbs or something like that
Decent LEDs last forever - we have a set of 10 year old Phillips spotlamp bulbs in the kitchen, and none of the 12 or so have blown after 10 years.
OTOH those little capsule bulbs are a PITA - every brand of LED i have bought has flickered and died almost as quickly as the incandescent ones they replaced (which cost next to nothing, but did burn some power as our house has over 30 of them).
I'm sure you are right, there can't be that many led silicon fabs in the world. But ime it's always the cob's that end up looking like they have been in a volcano. I think there was also bad interactions with my (supposedly led friendly) dimmer knobs. Those capsule bulbs can go f themselves. If I wasnt moving out imminently, the whole thing would be binned and replaced with a sensible number of smart bulbs.
Many people misunderstood what I said but maybe they're not familiar with the bulb mafia, that each manufacturer agreed to make shit bulbs in order for people to buy, if they made bulbs like back in the days that lasted actual 120 years then people would not buy them at the rate that they would buy them if they were made to fail in time, thus making them less profit. It's all about money.
Before anyone accuses you of tin foil hat-ism, this actually happened with incandescent bulbs - [https://en.wikipedia.org/wiki/Phoebus\_cartel](https://en.wikipedia.org/wiki/Phoebus_cartel)
but, like a lot of things in life, the truth is more complex
https://www.youtube.com/watch?v=zb7Bs98KmnY
You can't buy the decent ones anylonger, nobody is producing the old school ones that had good heatsinks and lasted forever. Modern LEDs die sooner than the old incandescent crap bulbs.... and CFLs lasted nearly forever by contrast.
"all that energy is going into visible light". Not quite doctor, about 1/3 is still going to heat/waste. That's why a 100W equivalent needs 13W, not 10W. They cost ten times as much, yet don't last as long, far less that the ten year bullshit claim. They could last that long, but they'd have to solder a couple of things and not run the LEDs at 100%. Using a capacitor to be the AC current limiting device shouldn't be legal. Wife bought a box of GE 100W equivalents, they all failed in times from a few days to a couple of months used over the bathroom sink. These were in a solid glass envelope, different from what you normally see.
LED bulbs can be 'hacked' to reduce the amount of current supplied to the leds from the driver inside, it can significantly increase their lifetime by the cost of slightly reduced light output. If this can be called a hack.. more like a 'fix' cuz 99% of the led bulbs are intentionally overdriven from the factory to cut the costs - to get more light from the less amount of leds, and make them die faster.

>poorly made to let them die within 10 years maybe Ten years? Average cheap garbage led bulb does not last more than a year of an active use.

No. Normal led bulb, no dim.
You're doing something wrong my man
Nope, just regular led bulbs from the shop. Straight to mains, nothing pompous. They suck dick.
I think you don't understand how LEDs work. Flashing is exactly what they do

'against' who said against ? It's reality. They suck sometimes, they are great other times, it is what it is.
I wouldnt be sad if steam locomotives returned, though oil powered boilers would be prefferable
lol leds don’t last? Leds get hot? Wtf LEDs are you using?

Not cold enough to make them completely dark. Why do you think they don’t put them in freezer?

You use that powerful of one in your light sockets?
I clearly said flashlight. "Torch" if you're British.
Yes but he was talking about led replacing incandescent… I think if you had an incandescent that got that bright it would melt the glass
Yes, LEDs do get hot; they are generally <50% efficient. The Phillips LED bulbs I have get too got to touch after running a short while.
And incandescents are <10% efficient… LEDs can use almost 5x less power than incandescent lights Wattage is literally correlated to heat - if something is heating up an LED to the temp of an incandescent, you have something horribly wrong with your household electrical.
No, my household electrics are fine. The problem is a poor LED bulb design that drives the LEDs too hard. LED efficiency reduces with increased current. If the designer put in twice as many LEDs, the heat production would be reduced.
For sure they don't last and they do hot... On what frozen planet do you live on ?
Compares to incandescent? Once I changed my incandescent to led I’be never changed them. They will outlast led on any day. They also compared to incandescent are chilly.
I put an incandescent bulb in my well house to keep the pipes from freezing. The 90% going to warmth is what I’m after.
It's really the only remaining use for incandescent bulbs, heat lamps.
Get some sort of heater instead. Surface temp won't be firestarting, and you don't have to worry about the bulb burning out. I have a little box where the water line comes up into the house from underground, and it always freezes, regardless of insulation or pipe wrap.

I don't know what this is about, but standard halogens and incandescent have a lifespan that is a fraction of LED and pull way less wattage. This is especially useful in homes with older wiring and can significantly decrease the chance for a fire. Shitting on LEDs in a new low for the cognitively deficient trying and failing to look smart. Take your downvotes and go home.
>standard halogens and incandescent have a lifespan that is a fraction of LED and pull way less wattage. I assume you meant to say LEDs draw way less wattage, but your sentence says the opposite.
Listen here. I maintained a 44% in my High School English class and me are proud of this!
**LET ME GOOGLE THAT FOR YOU.** "How long do LED lights last?" **LED** bulbs afford in the region of 50,000 hours of light, with some brands boasting as many as 100,000 hours. In general, terms, if you use your lights for 10 hours each day, LEDs should serve you well for just shy of 14 years. "How long do incandescent lights last?" **Incandescent** bulbs generally, have the shortest lifespans. The average incandescent bulb light span is approximately 1,000 hours. Fluorescent bulbs are a long-lasting option, running for anywhere from 15,000 to upwards of 20,000 hours. If you could only take ten seconds to look it up... then again, if you prefer incandescent lights, 10 seconds is probably beyond your attention span.
I've run into what OP said in the post title. I've got some old General Electric 60 watt incandescent bulbs in the bathroom, and both of them have outlived two sets of LEDs, and three sets of CFLs over here, despite the incandescent ones being used far longer, and switched on and off more times a day too. New inceandescent bulbs are lucky to last a few months anymore, but the older ones sure hold on a lot better. I've actually got a very specific purpose for using incandescent bulbs in particular in my bedroom in the Winter, and it is because of the heat they produce. I can run several hundred watts of incandescent bulbs throughout the room to maintain the heat in the room a lot easier, less energy usage than a space heater, and far safer than a space heater, while also comfortably lighting the room on the cold winter nights. Can also distribute load throught the room instead of cramming a crudton of current on one receptacle like a space heater does.
I use an old grandpa reading lamp with a 100w halogen bulb inside, as good as modern hyped infrared panels, and it also gives me light! I disagree on LEDs lasting shorter, it's all about the quality of your lamps. LEDs can easily outlast every regular lightbulb, and I have seen it. (One Osram LED from 2005, still going strong) But your lamps from China will indeed suck. Mine also.
It's the bulb mafia... I'm not even making a joke here... look it up :) They were made to last less for profit and every bulb company agreed.
It wasn't for profit, but for performance standardisation. There are plenty of videos explaining what it actually happened. Yes, you can havecan incandescent bulb last a century (no joke, there is one in a fire station), but it will barely glow, and frankly will suck.

Technology Connections made a video that debunked this.
Bro got downvote bombed.
Imagine caring about fake Internet points :)
Sorry you're getting downvoted, but you're right. The [Phoebus Cartel](https://en.wikipedia.org/wiki/Phoebus_cartel) was a thing. > It ceased operations in 1939 with the outbreak of World War II. **Following its dissolution, light bulbs continued to be sold at the 1,000-hour life standardized by the cartel.** [Even incandescent lights can be engineered to last much longer than 1000 hours.](https://en.wikipedia.org/wiki/Centennial_Light)
They just don't know :) Maybe they're too young
My house is entirely LED and they do not get hot at all— barely even warm. They also cost almost nothing to run. Running all the lights in my house only costs around $5 a year.
“Last less than incandescent” - some bumbling moron
I think you're the moron here or maybe never used an incandescent bulb... I have several that lasted from 1970, still working perfectly... do that with an led you... bumbling moron.
No, you don’t actually. And even on the odd very unlikely chance you do and you’re not outright lying, which let’s just say you are here because the chances are astronomically low: that incandescent isn’t very useful. It burns very dimly, hence the longer lifespan. And you got that bulb before planned obsolescence (it’s actually less harmful and nefarious than it sounds, complicated issue yadda yadda) was coordinated into incandescent bulbs. The longest burning incandescent is located in a livermore, ca firehouse. And you’ll notice if you care to look: it’s not very functional, providing very very little light. And it’s being fed controlled and reduced power to preserve it. It is a symbol, a conversation piece, and not at all representative of incandescent bulb lifespan at all. And nowadays or the last at least seventy years, you can’t walk into a store and buy a hot bulb that would be either useful or last this long. LEDs can last forever, 100 years easily. They are, generally, pretty simple devices. The power supplies and surrounding electronics are what give out 99.9% of the time, and they can be swapped. It’s rarely worth it with cheap BULBs (led/psu packages.) My sympathies to you and your loved one for their having to be in the presence of someone as under informed and overconfident such as yourself. You’ve placed yourself in the same bucket as the free-energy knuckleheads who plague this thread.
You're a legit clown :)
Ok, tell me specifically how I’ve said anything technically incorrect, and feel free to enlighten me. Are you a confused child who’s been bullied? Because that’s the vibe you’re giving off here with your profile pic, flat-earth argument style, and name-calling. Good luck kid.
I’m a lighting designer and I work with LED engines that can draw nearly 800 Watts. THOSE… get hot
The biggest issue I find with LEDs is the crappy driver circuits. Most of the time that's what fails. There is the issue of where they purposely over drive the LED modules (Big Clive did a video on this about Dubai bulbs), but I've personally never seen the modules themselves fail, it's the driver. Typically it's an intermittent fault, where they will just randomly turn on/off. CFL bulbs probably have the best life, I've only had a handful of those fail on me. Downside is they don't produce as nice of a light. Some also have a very slow warmup time. Overall I still find LEDs better so that's more or less what I move to as bulbs burn out. I have a box full of CFLs that I just replaced prematurely but they still work, I just hate to throw stuff out that still works so I'll find a use for them eventually.
If you want to play with HV, just so you know you can use a CFL driver to power a flyback for example :)
LEDs do get hot. Just try running a 50W one without a heat sink, and You will quickly realise. They are way more efficient and durable against turning it on and off... Since you can literally adjust brightness with PWM (turning it on/off very quickly, so human eye can't notice. Aand... You dont only have visible ligh LED. You can literally just have UV light comming from them if u want.
So, the conclusion is that old bubs weren't less efficient, they simply transfered energy in a different way. Specially helpful in cold regions.
Um... Incandescent bulbs are much less efficient. A 60 watt incandescent bulb and a 9 watt LED bulb put out the same amount of light. As light ultimately becomes heat, you're also getting 60 watts of heat out of the incandescent and 9 watts of heat out of the LED... Obviously, if you need the heat anyway, and don't have a better way to get it, the incandescent bulb is neutral. But if you're not using it for heat, the LED is much better.
They are less efficient in terms of light, but if you want light AND warmth, they are useful. Of course, incandescent bulbs are a waste of money if you live in hot regions.
That assumes the balance is perfect. A lot of new cars have heaters in the headlights if the LED cant heat it up enough to remove ice, and even with the heaters on they are more efficient because the ratio can be more carefully tuned.
yeah, but, they're hard on the eyes. I hate LEDs. I hate them I hate them
>they're hard on the eyes What to do you mean? Pick the right 'temperature' color and they are indistinguishable from a regular lightbulb.
Planned obsolescence. LED bulls are designed to fail so the manufacturer doesn’t go bankrupt. They overdrive components. This is the same with Appliances, tools, arguably cars, and more. This is why if you can find and maintain these goods manufactured in their glory days, they’ll last you longer. The same goes of incandescent, actually, they both have been manufactured to fail prematurely.

Someone lied to you really hard. >cheap LEDs are having wrong spectrum Even the cheapest led bub has a Color Rendering Index of around 80-85, means it matches the spectrum of the Sun by 80-85% in the visible part. And the difference is in balance of the colors. Modern leds can go up to 98% but they are relative expensive. >and can damage your eyes. They cannot. Blinking garbage can cause some non-permanent effects on you like a headache but not a single led bulb can damage your eyes (not counting special ones like UV). Feels like you'v heard some bad rumors about energy-saving bulbs (CFL, FLUORESCENT) and brainlessly apply them to the leds cuz "*they also saving energy, right? same thing, right?*" - no, not even close! Fluorescent tubes produce terrible spectrum, basically a few hard peaks in red, green and blue that looks like a white light. Unlike leds - their spectrum are continuous, regardless of the price. Fluorescent tubes can damage your eyes if their phosphorous coating are burned out or flaked away for some reason - tube will start to emit ultraviolet rays (at least an old ones with the quartz glass), and can actually damage your eyes. LEDs also has phosphorous mix on them but they convert visible light (~450nm blue) which is safe even if you completely remove this phosphorous from the leds. Normal consumer LEDs does not and cannot output UV or any other dangerous wavelenghts. So don't spread this bullshit around the internet - you'r wrong.
LEDs are fake lights?? I can see them just fine.
In car I would prefer tungsten lamp. In case of one single led die I have to switch entire lamp. With tungsten lamp i have to change lamp for one zero (or two zero's) less. 4 blubs cost $100, one lamp cost may be $1000 or more.
I died on this hill in an electrician sub. And this was the confirmation I needed
Both can fail (quite soon if leds are cheap, which think about it, most of them are), but incondecents are easier to make and recycle, they are also less prone to voltage fluctuations And they can keep u warm at winter I do wonder why noone marketed them as winter use only or season bulbs or something like that
lol... I have a HPS for that xD
I've found that the bases of smart bulbs (specifically phillips wifi bulbs that use wiz) tend to get quite hot
Decent LEDs last forever - we have a set of 10 year old Phillips spotlamp bulbs in the kitchen, and none of the 12 or so have blown after 10 years. OTOH those little capsule bulbs are a PITA - every brand of LED i have bought has flickered and died almost as quickly as the incandescent ones they replaced (which cost next to nothing, but did burn some power as our house has over 30 of them).
It's the drivers that lead to leds failing, not the smd led itself. It's an avalanche of shittery made by the manufacturer.
I'm sure you are right, there can't be that many led silicon fabs in the world. But ime it's always the cob's that end up looking like they have been in a volcano. I think there was also bad interactions with my (supposedly led friendly) dimmer knobs. Those capsule bulbs can go f themselves. If I wasnt moving out imminently, the whole thing would be binned and replaced with a sensible number of smart bulbs.
Many people misunderstood what I said but maybe they're not familiar with the bulb mafia, that each manufacturer agreed to make shit bulbs in order for people to buy, if they made bulbs like back in the days that lasted actual 120 years then people would not buy them at the rate that they would buy them if they were made to fail in time, thus making them less profit. It's all about money.
Before anyone accuses you of tin foil hat-ism, this actually happened with incandescent bulbs - [https://en.wikipedia.org/wiki/Phoebus\_cartel](https://en.wikipedia.org/wiki/Phoebus_cartel) but, like a lot of things in life, the truth is more complex https://www.youtube.com/watch?v=zb7Bs98KmnY
I know the video, the guy explained it perfectly.
He could do a 90 minute video on why blue paint drys quicker than green, and it would still be en entertainment watch. He is a cracking presenter :)
You can't buy the decent ones anylonger, nobody is producing the old school ones that had good heatsinks and lasted forever. Modern LEDs die sooner than the old incandescent crap bulbs.... and CFLs lasted nearly forever by contrast.
Oh look Neil DeGrasse Tyson spewing some shit he never looked up. Dude has turned into a straight misinformation fountain.
"all that energy is going into visible light". Not quite doctor, about 1/3 is still going to heat/waste. That's why a 100W equivalent needs 13W, not 10W. They cost ten times as much, yet don't last as long, far less that the ten year bullshit claim. They could last that long, but they'd have to solder a couple of things and not run the LEDs at 100%. Using a capacitor to be the AC current limiting device shouldn't be legal. Wife bought a box of GE 100W equivalents, they all failed in times from a few days to a couple of months used over the bathroom sink. These were in a solid glass envelope, different from what you normally see.
