DES C R IPTION
Recessed open downlight with 4 inch aperture for vertical PAR20 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 45° cutoff yields low aperture brightness. Universal housing
also accepts reflectors for open, open wall wash and lens 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.
Spun 0.050” thick aluminum
reflector provides 45° lamp and
lamp image cutoff. Distribution
based on lamp beam angle. Self
flanged standard with optional
white painted flange. Also available
with polymer trim ring. Trim ring
may be interchanged with metal
trim ring available in various
finishes or removed for rimless
installation, see accessories.
Available in all Portfolio Alzak®
finishes.
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.
