Portfolio MD620T4G65 Specification Sheet

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.
SPECIFICATION FEATURES
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-

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.

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.

Prepared by
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.
