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).

I've had sets of LED under-cabinet lights powered on 24/7 for about 14 years. I think one bulb went bad, out of 12.
