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).

    Hah, I have one three bulb boob light that’s my “trash” fixture because it gets whatever mismatched leftover I can find. At one point I had an LED, and incandescent and a CFL in it. It doesn’t have the extra ventilation that modern ones do so I’m sure it gets hot, but even that doesn’t seem to shorten the lives much
