ORDERING INFORMATION

DESCRIPTION

Recessed lens downlight with 6 inch aperture with vertical T4/T6 G12
ceramic metal halide lamp. Available in narrow, medium and wide
distributions. Fixture is suitable for commercial construction. Insulation
must be kept 3" from top and sides of housing. Two stage reflector system
produces smooth distribution with excellent light control and low aperture
brightness.

Mechanical Housing

Steel housing encloses optical
system protecting reflectors from
damage. Tool-less top access
allows service from above. Access
door allows splice inspection and
ballast service through aperture.

Plaster Frame/Collar

Die cast aluminum 1-1/2" deep
collar accommodates ceiling
materials up to 2".

Universal Mounting Bracket

Accepts 1/2" EMT, C channel and
bar hangers and adjusts 5"
vertically from above the ceiling.

Junction Box

(6) 1/2" and (2) 3/4" trade size pry
outs positioned to allow straight
conduit runs. Listed for (12) #12
AWG (six in, six out) 90°C
conductors and feed thru branch
wiring.

Fasteners

All fasteners that must be routinely
loosened or tighten for installation
and or maintenance are to be
captive.

Re-lamp

Suitable for top or bottom lamp
replacement. A lockout feature
prevents the lamp socket from
being installed in the incorrect
beam distribution position during
service.

Optical Upper Reflector

Clear anodized spun 0.050" thick
aluminum produces narrow,
medium and wide distribution
based on selected lamp center
position.

Lower Shielding Reflector

Hydro-formed 0.050" thick
aluminum parabolic contour
provides 50° lens and lens image
cutoff. Self flanged standard with
optional white painted flange. Also
available with polymer flange.
Available in all standard Alzak®
finishes.

Shielding

0.125" thick diffuse glass lens
masks arc tube support wire
image, striations and color
de-mixing common with uncoated
ceramic arc sources. Lens is
captive during lamp replacement.

Trim Retention

Upper and lower reflectors are
held securely together and are
retained with two torsion springs
holding the flange tightly to the
finished ceiling surface.

Electrical

Pulse rated G12 ceramic lamp
socket attaches to upper reflector
with three position bracket and
precisely maintains lamp center.

Insulation Detector

Self resetting detector opens
circuit if insulation is improperly
installed.

Ballast

Universal input 120/277V electronic
ballast provides noise free
operation, improved efficiency and
increase 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.

Quartz Lamp Re-strike Time
Delay System (Q Option)

Internal auxiliary 100W DC bayonet
base T4 quartz lamp (included)
provides low level illumination in
the event of a momentary power
interruption.

Emergency Circuit Lamp (X
Option)

Emergency circuit lamp module for
100W DC bayonet base T4 quartz
lamp (included) by emergency
circuit.

Code Compliance

Thermally protected and cULus
listed for protected wet locations.
Optional City of Chicago
environmental air (CCEA) marking
for plenum applications. EMI/RFI
emissions per FCC 47CFR Part 18
