They say that incandescent bulbs waste a lot of energy in the form of heat, while cfl's do not. I want to understand why this is so. They both produce white light? Is it a difference in the radiated spectrums of each type of bulb, or does it have to do with the mechanics of making light by glowing the element in the incandescent vs light emission from the excited gas in the cfl? I don't know the answer, trying to figure it out.
