Fluorescent lamps, or fluorescent linear tubes as
they are also known, are
categorized according to their
wattage,
shape
and diameter. The "T" in T5
indicates the bulb
is tubular
shaped,
while the "5" denotes that it is five
eighths of an inch
in diameter.
The other common lamps are the
larger T8 (eight
eighths inch = 1") and
T12 (twelve eights
inch = 1½" tubes).
The
T12 is
an older generation
fluorescent bulb that generates light
through
electromagnetic
induction, which is considered less
efficient method of
creating light
compared to that of newer
electronic based
circuits. Like the
T5, the
T8 tube creates light
through
advanced electronic circuits and are
available in standard 2,
3, 4, and 5 foot lengths. However, what sets
T5
fluorescent
lights
apart from T8 bulbs is their dramatic reduction
in size. T5
lamps
are 40% smaller than T8 fixtures, but are capable of
containing just
as
much and sometimes more light in a smaller
area. In
other
words, more T8
fixtures are needed to produced
the same amount
of
light generated by
significantly fewer high
output T5 bulbs.
Although the newest T5 lights
generally cost
more than T8 models,
they
are lower maintenance than other
fluorescent bulbs. This
combined with
the T5 bulb's ability to
provide more
light (lumen)
than the other
bulbs means long-term
cost savings on your
commercial and
residential projects.
