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

- Neither changes the thermodynamic state of the Universe (sum potential and kinetic energy).
- If you instead meant local to the house it's in, neither, 40W is 40W.
- If you meant from power station to end user, the halogen will incur slightly higher losses due to the low power factor in transmission (the difference will be on the order of 5%).
- If you meant the energy which is not serving a useful purpose (i.e., visible light used for illumination before it, too, is absorbed and downgraded to a lower heat grate), then the incandescent will win by 15-20%.
But a Good Engineer would know this already.

Probably the Halogen. It radiates in the horizontal axis if it is packaged in an edison base. Thus heating an enclosed fixture more than a classic incandescent.
Plus, who would use a halogen?, they are fire hazards.
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.

"Halogen lamps get hotter than regular incandescent lamps because the heat is concentrated on a smaller envelope surface, and because the surface is closer to the filament. This high temperature is essential to their operation. Because the halogen lamp operates at very high temperatures, it can pose fire and burn hazards."

Jim-out-of-touch-with-reality-Thompson went to MIT, but seems only to have absorbed a rather narrow education. He may be able to research stuff relevant to designing integrated circuits, but any skills that might have covered a broader spectrum - say physics - seem to have atrophied and dropped off a very long time ago.
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. ...Jim Thompson

That's a weenie answer. I suppose you'd say I should use CFL's ?:-) ...Jim Thompson

Enclosed fixture? I use Halogen floods in the kitchen. But I have LED's in the front entry lighting (25W equivalent). ...Jim Thompson
