Question

How many hours does the average light bulb last?

Answer 1

If you're talking about the new Led light bulbs we mostly use today then I can say for me an average LED light bulb that I have lasts me around 2 years at most before it starts to blink on and off and go dim.

The manufacture claims that the light bulb can last up to 10 or even 18 years but I never had an led light bulb last me that long yet.
