SPECIFICATION FEATURES
A…Construction
B…Electrical*
C…Shielding
Fiberglass housing is reinforced
polyester and self-extinguishing
(ASTM-D635-74) plastic of a
permanent pearl gray color. Top of
housing has five embossments
(2' unit), nine embossments (4' unit)
and thirteen embossments (8' unit),
providing mounting flexibility on
uneven surfaces. A watertite hub
for 1/2" conduit entry is provided at
each end of housing (standard) for
continuous feed. Polyurethane
gasketing is formed in the housing
providing a continuous seamless
seal for the diffuser. Six sturdy cam
latches clamp diffuser tightly for a
positive seal between housing,
gasketing and diffuser.
Unit has full metal gear tray secured
by internal fasteners and tethers
providing maximum protection
and rigidity. Ballasts are CBM/ETL
Class “P” certified. (Cold temperature ballasts are available for less
than 0°F starting with EHT (T5HO
only), EB/PLUS and ER/PLUS ballasts). Rotor lock lampholders.
Electrical components and fixture are
UL/CUL listed for Wet Locations.**
IP65 approved with optional
IP67 rating (4' only) with 8 latches.
New contemporary styled lens
clear acrylic w/impact resistant
additives and linear prisms.
“DR” - Clear low brightness
pattern acrylic with 15% high
impact additive.
“DR-100” - Clear low brightness pattern acrylic with 100%
high impact additive.

Relative Light Output Factors
To accurately predict how luminaires will perform in cold temperatures,
Cooper Lighting individually tested each configuration in the different
ambient environments. The relative light output factor should be
applied as an additional light loss factor component.
