DESCRIPTION
Recessed downlight luminaire with 1-3/4 inch square pinhole aperture
utilizing a low voltage MR16 tungsten-halogen lamp. Modular platform can
be reconfigured from below the ceiling to accept a broad range of lamp
modules and optical elements. Platform is suitable for direct contact with
insulation and 2x8 residential construction. Platform + module + element
combination supports various lamp beam spreads for desired optical
distribution with excellent light control and low aperture brightness.

Frame
Galvanized steel plaster frame with
integral bar hanger receivers.
Setscrews provide positive
horizontal locking.
Collar
Matte black steel collar adjusts
vertically for 1/2" - 1" thick ceilings
and can be rotated +/- 7.5° thru the
aperture. Integral gun sights
facilitate the use of guide strings or
laser lines. Shipped with a paint
overspray protector installed in the
collar.
Lamp Module
Installed or removed thru the
aperture or from the top and
allows lamp orientation at 0°, 90°,
180° and 270° positions.
Housing
Double wall aluminum housing
painted matte black for a visually
dark interior. All fasteners are
captive.
Gaskets
Closed cell gaskets achieve
restrictive airflow requirements
without additional caulking.
Bar Hangers
Captive preinstalled bar hangers
adjusts from 8-1/2" to 24" wide;
pass thru feature allows shortening
without removal. Captive nail
penetrates standard and
engineered lumber. Mounting
flange levels platform with ceiling.
Integral clip attaches directly to
t-bar.
Pinhole
Diecast aluminum flange with
black occulus providing glare
control. Occulus can be removed
to facilitate painting or to create a
larger (2-1/4") square aperture.
Mousetrap type springs pull flange
tight to ceiling. Light trap
eliminates spill light at edge of
flange. May also be installed flush
to ceiling using optional plastering
lathing ring. Provided with both
straight and angle cut parabolic
shielding cone, shipped with angle
cut version installed.
Junction Box
(7) 1/2" trade size pry outs, (3)
integral clamps for non-metallic
cable. Rated for (4) #12 thru branch
circuits. Wago® type push wire
connectors for field connections.
Thermal Protector
Self-resetting thermal protector
protects against improper lamping.
Transformer
Integral dual output toroidal
magnetic transformer, 120V
50/60Hz input, 12V nominal 75VA
maximum output. Separate output
for circuits controlled by dimmers
compensates for losses in
dimmers, improves color
temperature and lumen output.
Lamp Capsule
Ceramic GX5.3 lamp holder
mounts to an aluminum heat sink
to dissipate heat. Connects to the
transformer with electrical quick
connects. Accepts 2 lenses, filters
or optional lamp snoot.
Code Compliance
Thermally protected, IP labeled,
cULus listed for damp locations
and ASTM-E283 AIRTITEtm.
Suitable for direct contact with
insulation.
