About
Fluorescent Lamps Fluorescent lamps are high efficiency lamps utilizing
an electrical discharge through low pressure mercury vapor to produce ultra-violet
(UV) energy. The UV excites phosphor materials applied as a thin layer on the
inside of a glass tube, which makes up the structure of the lamp. The phosphors
transform the UV to visible light. Important performance specifications to consider
when searching for fluorescent lamps include rated average life, lamp power, initial
lumens, mean lumens, color rendering index, and color temperature. The rated average
life refers to the lamp burning hours to median life expectancy. The lamp power
specifies the wattage of the lamp. Initial lumens are the initial light output.
A lumen is the international (SI) unit of luminous flux or quantity of light.
Mean lumens specify the average lamp output over a designated amount of time (usually
40%-50% of the rated lamp life). A lumen is the international (SI) unit of luminous
flux or quantity of light. The color rendering index is an indication of the ability
of the lamp to render object colors in a normal, natural way. The higher the number
(0-100), the better the color appearance. The color temperature is a measure of
the visual "warmth" or "coolness" of the light from the lamp.
The higher the value, the whiter or "cooler" the light appears.
The
nominal length specifies lamp size for fluorescent lamps, which is the overall
length of the lamp. Choices for lamp base for fluorescent lamps include single
pin T-6, single pint T-8, single pin T-12, bi-in T-5, bi-pin T-8, bi-pin T-10,
bi-pin T-12, recessed double contact T-8, and recessed double contact T-12. A
single pin T-6 lamp has a single pin and is small in size. A single pin T-8 lamp
has a single pin and is medium in size. A single pin T-12 has a single pin and
is large in size. A bi-pin T-5 has a two pin connection and is miniature in size.
A bi-pin T-6 has a two pin connection and is small in size. A bi-pin T-10 has
a two pin connection and is medium in size. A bi-pin T-12 has a two pin connection
and is large in size. A recessed double contact T-8 has a two pin connection that
is recessed and is small in size. A recessed double contact T-12 has a two pin
connection that is recessed and is large in size. Fluorescent lamps are

color rendering index is an indication of the ability of the fluorescent lamp
to render object colors in a normal, natural way. The higher the number in color
rendering index (0-100), the stronger the appearance of color. The color temperature

T-5 lamps have a two-pin connection and are miniature in size. Bi-pin T-6 fluorescent
lamps have a two-pin connection and are small in size. Bi-pin T-10 lamps have
a two-pin connection and are medium in size. Bi-pin T-12 lamps have a two-pin
connection and are large in size. Recessed double contact T-8 fluorescent lamps
have recessed two-pin connections and are small in size. Recessed double contact
T-12 fluorescent lamps have recessed two-pin connections and are large in size.
