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).

    Get the ones with the strip LEDs that look like they’re trying to emulate a glowing tungsten filament. I can’t remember where I got the information; it was like the Technology Connections YouTube channel or something, but I remember them saying that since they put the LED lights in series on those bulbs, they have a much higher voltage requirement to drive them, and much less circuitry is needed. It’s the circuitry that burns out, and many of these filament-style LED lights literally only have a resistor as their main component.

    I’ve swapped to these kinds of LEDs like…5 years ago, and haven’t had one burn out yet. Probably have like…15 of them across the entire house.

      Almost every bulb in my house is the filament style and it’s always surprising when one dies. The 4 in my porch lights are on 24/7, in all weather of course, and have been for 4 years.
