WebOct 30, 2024 · So, in short, fluorescent lights make their energy in a three-step process: Electrodes take electrical energy from the power supply and generate moving electrons. The moving electrons collide with mercury atoms in the tubes to make ultraviolet light. WebA fluorescent bulb produces less heat, so it is much more efficient. A fluorescent bulb can produce between 50 and 100 lumens per watt. This makes fluorescent bulbs four to six times more efficient than incandescent bulbs. That's why you can buy a 15-watt fluorescent bulb that produces the same amount of light as a 60-watt incandescent bulb.
