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 have 7 bulbs since 2019
    none of them failed so far.

    all the lifespans i found ranged between 15.000 to 25.000 hours ( which btw was equated to 1.000 hours per year instead of 5.000 per year)

    so this doesn’t sound normal to me.

    how manny(in use) bulbs do you have?
    what brands do you use?
