4.3 Characteristics of Compact Fluorescent lamp

Compact Fluorescent lamps (CFL) are available in a variety of styles or shapes. Come have two, four or six tubes. Older models and specialty models have separate tubes and ballasts. Some CFLs have the tubes and ballast permanently connected. This allows you to change the tubes without changing the ballast. Others have circular or spiral-shaped tubes. In general, the size or total surface area of the tube determines how much light the bulb produces.

4.3.1 Efficient

CFLs are four times more efficient and last up to 10 times longer than incandescent. A 22 Watt CFL has about same light output as a 100 Watt incandescent. CFLs uses 50-80% less energy than the incandescent.

4.3.2 Versatile

CFLs can be applied nearby anywhere that incandescent lights are used. Energy efficient CFLs can be used in recessed fixtures, table lamps, track lighting, ceiling fixtures and porch lights.
