fluorescent vs incandescent efficiency

A fluorescent bulb produces less heat, so it is much more efficient. That's why you can buy a 15-watt fluorescent bulb that produces the same amount of light as a 60-watt incandescent bulb. Incandescent (right) and fluorescent light bulbs side to side Incandescent light bulbs vs Fluorescent light bulbs.

At below-freezing temperatures standard lamps may not start. The luminous efficiency of fluorescent lighting is the highest, between 9 percent and 11 percent for most CFLs, while conventional incandescent bulbs … ... At much lower or higher temperatures, efficiency decreases. What is the difference between incandescent and fluorescent light bulbs? The fluorescent lamp and CFL are more efficient in converting electrical energy to light than the incandescent bulb. A fluorescent bulb can produce between 50 and 100 lumens per watt.

Under extreme conditions, its lifespan may be much shorter than a cheap incandescent lamp. A luminous efficacy, to put it simply, is the amount of Lumens per watt in the lighting unit. The luminous efficacy of incandescent light bulbs is relatively low. Incandescent bulbs produce a direct light from the heating of the filament whereas the fluorescent bulb produces a secondary light through fluorescent material. Incandescent vs Fluorescent. This makes fluorescent bulbs four to six times more efficient than incandescent bulbs.
