Doesn't the bulb emit one part light and six parts heat? So 6/7ths is 85.7 watts wasted energy in the form of heat. :eek: starting to sound like the oracle (6/7/100:confused:)

Wiki gives 2W to light and 98W to heat, but who's to say?

Are you guys assuming a light bulb?
Could be a black bulb? :)

I think that 100W will be heating. 98W is direct heating, 2W is heating through the light.

I think that the OP is too rude to respond, another one-post wonder.

My pocket calculator just grew a fist and jabbed me one for entering too many numbers. Besides, you forgot the() and%.
