Compact fluorescent lamp

Compact fluorescent lamps are smaller versions of standard fluorescent lamps. They consume between 5 to 27 watts, and have a brightness and color interpretation that is equivalent to incandescent lights. Unlike standard fluorescents, they can directly replace standard incandescent bulbs. Compact fluorescent lamps (CFLs) combine the energy efficiency of fluorescent lighting with the convenience and popularity of incandescent fixtures.

Working of CFL

Compact fluorescent lamps work to a great extent like standard fluorescent lamps. They consist of two parts:

1. A gas-filled tube
2. Magnetic or Electronic ballast

The gas in the tube glows with ultraviolet light when electricity from the ballast flows through it. This in turn excites a white phosphor coating on the inside of the tube, which emits visible light throughout the surface of the tube. Compact fluorescent lamps with magnetic ballasts flicker slightly when they start. Besides, they are heavier than electronic ballasts. Electronic ballasts are more expensive than magnetic ballasts. However, they are more efficient especially at low temperatures. Most currently available CFLs have electronic ballasts.
