Desk lamps are perfect for illuminating a workspace. For
the best results choose a lamp that produces the right
amount of light for your needs. A good starting point is to
select the type of light bulb you want to use.
Desk lamps differ in their bulb types, which vary in the
wattage and quality of light they produce. The higher the
wattage of a light bulb, the more light and heat it gives
off. When shopping for a lamp, be sure to note the wattage
rating of a light fixture and never exceed this number.
The following is a ranking of the different types of bulbs
by efficiency and life span:
Medium base bulbs are your standard incandescent bulbs that
vary from 15 to 150 watts. These bulbs cast a soft
yellow-white light.
Compact fluorescent light bulbs (CFL) differ in size, shape
and electrical contact. The bulbs are small and have a
corkscrew shape with all the electrical contacts at one
end. The bulbs can be used in a standard medium base
socket. CFLs are more efficient than incandescent bulbs and
produce a light that is more like real sunlight.
Halogen bulbs emit a bright white light and last longer.
However, a clean cloth should be used when handling a
halogen bulb as oils from your hand can reduce the life
span of the bulb.
Fluorescent bulbs cast a true light, and they last longer
and are more energy efficient.
