FLUORESCENT LAMPS
The bulb shape and size of a fluorescent lamp
are expressed by means of a code consisting
of the letter “T” (which designates that the
bulb is “tubular” in shape) followed by a
number that expresses the diameter in eighths
of an inch. Diameters range from T2 (
1
⁄4 inch)
to T17 (2
1
⁄8 inch). In nominal overall length,
linear fluorescent lamps range from 6 to 96
inches. The nominal length is measured from
back of lamp holder to back of lamp holder.
For example, the actual overall length of the
40-watt rapid start T12 lamp with a nominal
length of 48 inches is 47
3
⁄4 inches. The
nominal length given for PENTRON
®
linear
lamps is the closest familiar nominal length.
CURVALUME
®
U-shaped fluorescent lamps are
available as OCTRON
®
T8 lamps with leg
spacings of 1
5
⁄8 inches and 6 inches and as
rapid start T12 lamps with 6 spacings of 6
inches. The leg spacing is measured from the
center of one leg to the center of the other leg.
The overall length of the CURVALUME lamps
is measured from the face of the bases to the
outside of the glass bend. Circline lamps,
which are circular in shape, are available as
T9 lamps with outside diameters of 6
1
⁄2, 8,
12 and 16 inches as well as PENTRON T5
lamps with outside diameters of 8.85 and
11.77 inches.

BASES
For linear Preheat and Rapid Start Lamps, four electrical
contacts are required, two at each end of the lamp. This is
accomplished in the standard line of lamps by the use of a
miniature bipin base for T5 lamps and a medium bipin for T8
and T12 lamps. The OCTRON
®
T8 medium bipin lamps may
also be operated as instant start lamps with the proper
wiring and ballasts. When operating OCTRON bipin lamps
with instant start ballasts, the two contacts in the lamp
holder are shorted together and connected to the single
circuit in the ballast. In Circline lamps, the cathodes are
connected to a four-pin base located between the junction of
the two ends of the lamp. High Output (HO) and Very High
Output (VHO) lamps have recessed double contact (RDC)
type bases. Slimline Instant Start lamps require only two
electrical contacts, one on each lamp end and have single
pin bases.
