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 non consumer limits.
