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.
Not true. I’ve been dumpster-diving for LED bulbs for 5 years and in the majority of cases, it’s one LED in a series chain that burns out (fails open circuit). As for the circuitry, the most common failure point is the inductor between the capacitors smoothing out the rectified mains voltage.
Mains filament bulbs with nothing but a resistor exist but they flicker between 0 and 100% at 100 or 120 Hz, which is not very pleasant. Good filament ones have circuitry very similar to the plastic ones. The reason filament bulbs last longer is better heat dissipation from the LEDs, and the circuitry does not get too hot either.
