What compact fluorescent light bulb do I buy to replace a 60-, 75-, 100- or 150-watt incandescent bulb?
While a regular incandescent bulb uses heat to produce light, a fluorescent bulb creates light using a far more energy-efficient method — in fact, 4-6 times more efficient. This means that you can buy a 15-watt compact fluorescent bulb that produces the same amount of light as a 60-watt regular incandescent bulb. Here are the watts needed by regular incandescent light bulbs to match the light output of an energy-efficient Earthmate CFL light bulb.
