D ES C R IPTION
Recessed lens downlight with 4 inch aperture for vertical ED17P/PAR
protected medium base metal halide lamp. Universal input electronic
ballast features end of life shutdown. Fixture is suitable for commercial
construction. Insulation must be kept 3" from top and sides of housing.
Lower parabolic shielding cone with 50° equal lens and lens image cutoff
yields low aperture brightness. Universal housing also accepts reflectors
for open, open wall wash and PAR lamp applications.

Die cast aluminum collar
accommodates ceiling materials up
to 1-1/2” thick. Stilts adjust quickly
and accurately to accept reflectors
for ED17P, PAR lamps, open, open
wall wash, and lens applications.
Clear anodized spun 0.050” thick
aluminum produces medium
distribution when used with non
beam forming lamps.
Pulse rated E26 medium base
protected socket prevents use with
lamps not suitable for open fixture
use.

Universal input 120/277V electronic
ballast provides noise free
operation, improved efficiency and
increased lamp life as compared
with magnetic ballast. Regulated
output power over a wide range
of ANSI lamp voltages results in
excellent color stability over time.
End of lamp life shutdown – reset
power to restore output.
