Recessed downlight luminaire with 2 inch square regressed 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.
Galvanized steel plaster frame with 
integral bar hanger receivers. 
Setscrews provide positive 
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 
Installed or removed thru the 
aperture or from the top and 
allows lamp orientation at 0°, 90°, 
Double wall aluminum housing 
painted matte black for a visually 
dark interior. All fasteners are 
Closed cell gaskets achieve 
restrictive airflow requirements 
without additional caulking.
Captive preinstalled bar hangers 
adjusts from 8-1/2" to 24" wide; 
pass thru feature allows shortening 
without removal. Captive nail 
engineered lumber. Mounting 
flange levels platform with ceiling. 
Integral clip attaches directly to 
Diecast aluminum splay has 
truncated paramid with regressed 
square aperture providing minimal 
ceiling presence. Can be painted to 
match ceiling finish. Mousetrap 
type springs pull flange tight to 
ceiling. Light trap eliminates spill 
light at edge of flange. May also be 
installed rimless using optional 
plastering lathing ring. Provided 
with both straight and angle cut 
parabolic shielding cone, shipped 
with angle cut version installed.
(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
Self-resetting thermal protector 
protects against improper lamping.
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 
temperature and lumen output.
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 
Thermally protected, IP labeled, 
cULus listed for damp locations 
and ASTM-E283 AIRTITE(tm).
