Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.

Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

are there cool/non-warm colored filament led bulbs? My SO prefers the cool colored bulbs.
I’d be shocked if there aren’t.
They never last that long, as they easily get away with it.
In one of the gulf states, though (Dubai?), they actually have only longer lasting LED lights for sale, as the minister responsible for regulation is something like an EE and forced the LED bulb providers to make a special version of those bulbs that basically last for ever. Those are only sold in that country, and hard to come by elsewhere.
Planned obsolescence
Since people are just giving snarky douchebag replies, I'll actually attempt to answer the question since that's what this community is for?
The estimate given on the packages of these bulbs are absolute best case scenario, using an optimal temperature range and pattern of use that won't really match up with the average household because:
-
You may go on vacation and let your house get cold or hot. This could affect the life of thr bulb
-
The manufacturer is likely leaving the bulbs on 24/7 when measuring. Most people turn lights on and off multiple times throughout the day. This can decrease the life of thr bulb, just like with any other electronic device.
-
Humidity in the house can change dramatically year round. Manufacturing tests probably keep a constant humidity level.
-
If you're buying cheap random LED bulbs off Amazon from dogshit brands (i do thid too so not knocking you), the manufacturer estimates might just straight up be a lie.
I'm sure there are other reasons but that's a good start.
LEDs can take quite a beating. The only thing that degrades then is being on, and being hot. For all purposes unless it's inside a restaurant kitchen or they're on, they're not hot.
Other packaged electronic components follow the same rules. Except wires and solder that can oxidize without being used.
So no, I think that's a grift if you can't reach 5 years. When domestic LED lighting was in infancy we'd hear all power LEDs, like for cars, should last 10 years.
It wouldn't degrade from being shut off and on a bunch of times? I know like HDDs can degrade faster if they're constantly powered off and on.
Appreciate the feedback. I just tried to answer the question the best I could since at the time most of the replies were unhelpful and rude
Mechanical things suffer a lot of stress from turning on/off. But even spinning disk storage turns off automatically if desktop is idle for a certain time, it's a balance between switch vs continuous operation, they have overlapping kinds of wear and tear.
Top of mind, you can expect 10k cycles from typical buttons and it's hard to be less complex than a button. Because metal parts are subject to fatigue.
Flash based drives would certainly fail faster or slower depending on the number of write bytes over its life.
Then there's erosion caused by electrons, which is my biggest suspect for the problems of last generation of Intel CPUs. You have to royally screw up to start selling something that overlooked this.
Yea I don't think I'll buy Intel again. My next CPU upgrade will likely be an AMD ryzen chip.
Wait until you hear AMD is treating OEMs now as bad as Intel did on their most glorious moments.
I'll try to buy as few computers as I can until Risc-v is main stream.
Stop buying the cheap ones. :-)
? What are you talking about?
No stupid questions
Maybe stop buying the seizure-brand ones from Amazon?
I think I've had to replace one bulb in my entire house in the last 6 years or so.
Smart bulbs like this:
Have PCBs with small LEDs surface mounted to them. This means that the on-off cycle of the bulb causes heat deformation cycles of the PCB. This stresses the foils in the PCB and can eventually cause them to lose connection. That’s one of the reasons why they’ll often start flickering or lose the ability to be cool white, warm white, or specific colors (the different kinds of LEDs in them).
But bulbs like this (often called smart edison bulbs):
Use longer/larger LEDs that aren’t mounted to the PCBs, and will probably last much longer. They are better at not overheating their own electronics.
If you want the first kind to last longer, don’t run them above ~60% brightness.
Are you sure? Doesn't the "smart edison bulb" design make it harder to dissipate heat to the casing, therefore making the LEDs get hotter compared to PCBs with LEDs surface mounted on them?
Anyway, if you want your ~~light bulbs~~any technology to last long, don't buy the "smart" variant. "Smart" usually means more components and/or more dependencies on interfaces, and more complexity, so a higher chance to fail.
Only buy Philips (not the Hue stuff) or Osram
The rest are shite
I've got several full color Hue bulbs that are the most used lights in my house. I haven't had a single failure in a decade.
I was more than a little annoyed when they decided to stop supporting my original controller for them though.
+1 for philips.
The problem is most of what the big box hardware stores in the US are selling are junk brands. And they won't even offer basics like a philips 75-watt-equivalent soft-white led in their stores.
The junk brand bulbs will fail in my kitchen light fixture after a year (they start flickering). The philips bulbs have never failed for me.
A properly designed and produced led bulb should last like 20 years.
Ikea’s are nice too
Osram literally means "I'll shit on it" in polish, they are the definition of a shit brand
Millions of electricians would disagree, but I can't speak for Polish sparkies
It's a joke in Poland - what shines and actively threatens you? A lightbulb made by Osram
Ha ha brilliant, I'll remember that one 😊
They don’t? What are you talking about?
Is Lemmy worse than Reddit to answer no stupid questions?
Yes Lemmy is just as dogshit, if not more than Reddit in terms of smug bullshit replies. I'll be downvoted to oblivion by saying this so hopefully someone sees my comment before it goes to the bottom...
Edit: yep. Already downvoted lol. God forbid i criticize Lemmy. I guess ya'll ain't interested in making it a better place?
Cheap ones do.
I have still to have a led light break. They just never do, I buy mine at aliexpress or IKEA or wherever.
I have never had that happen and I buy my bulbs from the grocery store
I've had brand new ones that were duds before.
US?
I'm no scientist, but I think it has something to do with actually turning the light off and on that's actually stressful to most light bulbs. I mean check out the Centennial Light (wiki link). I know it's an entirely different type of lightbulb, but they have run that light almost continuously since 1901, and it's largely believed that continuous operation has kept it going for so long (though it has dimmed quite significantly).
I suspect that 20,000 hours operation is likely expected under continuous illumination, not ever turning the light off.
LEDs literally work by flickering constantly, they are always turning off/on. The answer is planned obsolescence. Technology connections video on the topic. There is also veritasium one.
I think he thinks about heat generation. A PWM signal (the 'flicker') won't do anything bad, but it will still generate heat, or not when it's turned off.
Not everything is planned obsolescence, some is just badly engineered cheap stuff.
