Default What is it that causes home light bulbs to fail ?

In article , says...

In another thread, it was mentioned that CFLs and LEDs
last longer than incandescent bulbs.

We all know incandescent bulbs fail due to the filaments
being made so thin that they oxidize and burn up, over time.

But, what causes CFL bulbs to fail?

And, what causes LED bulbs to fail?


Greed on the part of the manufacturers (for all light bulbs which do not
last long). The bulb burns out, you buy a new one and they make more
money!

This bulb has worked for over 110 years...
