Why does LED lights do not last 20,000 Hours?

LED lights should last 20,000 hours according to the package but it does not last that long as you know in many cases. Also, LED lights drop not suppose to heat up, but they do. Why?

Well, LED (Light Emitting Diode) does work in DC (Direct Current) but households are running AC (Alternate Current). That means, each LED light build must convert DC to AC. Yes, there is a little AC/DC converter inside each LED light bulb.

That is what is causing the LED lights to heat up. Also, when LED lights go out, it is often AC/DC converters are the one that burnt out not LEDs themselves.
