How long should it take for a lightbulb to explode from heat?

[qld]

I know of a 100 watt lightbulb that was left on overnight and exploded in the morning.

Does anyone know how long one should take to explode?

Never.

Only problem is if the bulb is enclosed in a fitting of lower wattage rating.

A lightbulb should not explode under normal circumstances.


Unless it's covered in mould (http://www.woodworkforums.com/showthread.php?t=101428) of course....

What sort of fitting would you use for a 150w bulb?

Some sort of thing that is 100% metal?

A fraction of a second. :wink:

Well I'm no explosives expert but a fraction of a second seems about right.

Depends on the application, is this an outdoor light ? If so what is it lighting up? Need a little more info to help out.

A standard incandescent lamp isn't really all that great once you go over 60W, if you need more light then an alternative light is generally better, mercury vapour, metal halide etc, but it really depends on what you are trying to do...

Light bulbs never explode..........they implode. :D

The light bulbs on but nobody's home.

Youre assuming its the light bulb exploding. It could be a case of exploding mould.

Im guessing a lightbulb in a ceiling connection will explode faster than a single lightbulb hanging from a cord?
