<< Well, you may be confusing temperature with heat. They're related, but you can have something at a high temerature that doesn't have alot of heat. So, the filament may be at a really, really high temperature, but there's not very much of it. >> Light color is measured in Kelvin degrees. Normal sunlight is 5400. 6000 would be a little blue-the higher the degrees, the blueer the light-and these new headlights do indeed look blue. Indoor light bulbs are about 3200 to 3400-on the red side. Color film has to be balanced for the correct color light. There are movie lights-commonly called HMIs after the first company to make them-that are balanced for daylight but they're a big deal and required lots of generator power. Color print film can have the color corrected in printing-that's why if you take pictures indoors without flash they look red. They can be reprinted to look normal. Phil Brown
