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).

LEDs literally work by flickering constantly, they are always turning off/on. The answer is planned obsolescence. Technology connections video on the topic. There is also veritasium one.
I think he thinks about heat generation. A PWM signal (the ‘flicker’) won’t do anything bad, but it will still generate heat, or not when it’s turned off.
Not everything is planned obsolescence, some is just badly engineered cheap stuff.
