*About Fluorescent Lighting
Fluorescent lamps are more efficient than incandescent light bulbs because a greater proportion of the power used is converted into usable light rather than heat, allowing the fluorescent lamp to run cooler. Thus a fluorescent lamp requiring 50 watts of power, for instance, produces as much light as a 250 watt incandescent light bulb, but with up to 90% less heat
