How come LED Light Bulbs only last for about 2-3 Years? - Lemmy.World

How come LED Light Bulbs only last for about 2-3 Years? I’ve bought and replaced a lot of light bulbs, and I noticed that all of them said “up to 20,000 hours” which would be about 5 years given 12 hours of daily use (which we definitely don’t).

Generally because you’re buying cheaper ones that aren’t built as well. Heat destroys LEDs and the cheap bulbs generally use fewer individual LEDs running at higher power to produce a given output in lumens. More expensive bulbs use more LEDs at lower power to achieve the same light output so that they’re not constantly being overdriven and last much longer.
What would you recommend?
I have dozens of Philips Hue bulbs 6-10 years old and I honestly don’t think one of them has died. I’m sure they have lost some luminance over time, but they still get the job done no problem. I rarely run them at 100% anyway.

I bought three of the gen 1 Philips Hue when they first came out and all three died within two years. I hope they’re better now, but I’ll never buy Philips Hue again.

And in case you ask, they weren’t enclosed, they were in IKEA floor lamps. They were at 100% all the time, but I feel like if they can’t survive that, they shouldn’t be able to do it.
