 Compact Fluorescents-
[ Up ] [ Next ]
Compact fluorescent lamps (CFLs) are smaller versions of standard
fluorescent lamps. They consume between 5 to 40 watts, and have a
brightness and color rendition that is comparable to incandescent lights.
Unlike standard fluorescent lamps, they can directly replace standard
incandescent bulbs.
CFLs are available in a variety of styles or shapes. Some have two,
four, or six tubes, while some have a circular tube. New versions have a
spiral-shaped tube. The size or total surface area of the tubes)
determines how much light it produces. Some CFLs have the tubes and
ballast permanently connected. Other CFLs have separate tubes and
ballasts. This allows you to change the tubes without changing the
ballast. There are also types that are encapsulated in a glass globe.
These look somewhat similar to conventional incandescent light bulbs.
CFLs have the following advantages over incandescent light bulbs when
used properly: they last up to 10 times longer, use about 1/4 the energy,
and produce 90% less heat, while producing more light per watt. For
example, a 27 watt compact fluorescent lamp provides about 1800 lumens,
compared to 1750 lumens from a 100 watt incandescent lamp.
The following is a comparison between the wattage of commonly available
incandescent lamps and the wattage of a CFL that will provide similar
light levels:
25 Watt Incandescent = 5 Watt CFL
50 = 9
60 = 15
75 = 20
100 = 25
120 = 28
150 = 39
