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).

Osram literally means "I'll shit on it" in polish, they are the definition of a shit brand

Millions of electricians would disagree, but I can't speak for Polish sparkies

It's a joke in Poland - what shines and actively threatens you? A lightbulb made by Osram

Ha ha brilliant, I'll remember that one 😊
