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).

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.
