ORDERING INFORMATION

DESCRIPTION

Recessed lens downlight with 6 inch aperture with vertical T4 GU6.5 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 alumi-

num parabolic contour provides

50° lens and lens image cutoff. Self

flanged standard with optional

white painted flange. Also avail-

able 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 GU6.5 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 opera-

tion, 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 environ-

mental air (CCEA) marking for

plenum applications. EMI/RFI

emissions per FCC 47CFR Part 18

non-consumer limits.
