D ES C R IPTION
Recessed 6 inch aperture directional / slope for PAR20 metal halide lamp.
Lamp rotates 365° and tilts 35° about the center of the aperture at the
ceiling plane. Distribution based on lamp beam angle. Universal input
electronic ballast features end of life shutdown. Fixture is suitable for
commercial construction and shallow plenum. Insulation must be kept 3”
from top and sides of housing.

A dj us tme nt Mechan ism
S ock et
Steel housing encloses lamp
adjustment mechanism and is
painted matte black to reduce
stray light. Top access allows
service from above. Access door
allows splice inspection and ballast
service through aperture.
Locking adjustment mechanism
rotates 365° and tilts 35°. Center
beam optics aligns axis of lamp
with aperture as lamp translates
from nadir thru 35°. Lamp aiming
scale enables consistent settings
across multiple fixtures.
Pulse rated E26 medium base
protected socket prevents use with
lamps not suitable for open fixture
use.

with optional white painted flange.
Also available with polymer
trim ring. Trim ring may be

B allast
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.
