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).

Speaking from experience: LED drivers hate dirty power. If they burn out frequently, check the wiring for damage. I probably avoided a house fire.
Dirty power? Aww geez it’s been a few years since I last washed and waxed my power lines. Guess I gotta open up the walls again.
That’s a good point. LEDs dislike unstable power a LOT more than incandescent or fluorescent.
As an EE graduate I want to hear more about what dirt means and what driver can be affected by it. I’d expect power electronics to stand 100% over voltage over short periods and easy 20% long term, which would blow up lots of other things on the house before the driver or the LED starts performing worse.
