A dj us tme nt Mechan ism
In su latio n Detecto r
Steel housing encloses lamp
adjustment mechanism and is
painted matte black to reduce stray
light. Tool-less 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.
Self resetting detector opens circuit
if insulation is improperly installed.

Die cast aluminum collar
accommodates ceiling materials up
to 1” thick.
Angle cut 0.050” thick aluminum

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.
