Loony Question for Today...

Which produces more HEAT, a 40W Incandescent, or a 40W Halogen bulb?

...Jim Thompson


Technically the incandescent. The both consume 40 watts but the halogen
is
more efficient at converting power to light (and hence not to heat). I
said 'technically' because you are unlikely to notice the difference in
heat.


My thoughts, too. I have a fixture rated for three 40W miniature base
incandescents, presently loaded with three 40W Halogens. My
temptation is to go up to three 60W Halogens.

I'm not sure exactly what you're after but maybe one of these would be
about right

There is a ship load of them and running them save you money.
