Interesting incandescent light bulbs fact

Umm... no....
The tungsten filament is heated to not far off its melting point, it has to be that hot to give off white light. However, this high temperature allows diffusion to occur, resulting in certain sections of the filament growing progressively thinner. The bulb fuses when turned on again as the initial surge in power heats the thinned section to melting point, breaking the circuit.

If this is true, that explains why the lamp in my room has been on for the past 4 years and never burned out.

Damn, that first word is hard to read when you're a little tippsy.

programmed obsolescence anyone?
don't know if its said exactly like that in english but...
