IRIS
DESCRIPTION
Recessed directional luminaire with 2 inch square regressed
pinhole aperture utilizing a low voltage MR16 tungstenhalogen 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 2x6 residential or
shallow plenum commercial construction. Insulation must be
kept 3" from top and sides of housing. 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
Steel housing painted matte black
for a visually dark interior. Removable
hinged top allows for top access. 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.
Butterfly Bracket
Provides 3" of vertical adjustment
and accepts 1/2" EMT, C channel or
bar hangers.
Splay
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.
Junction Box
(7) 1/2" trade size pry outs, (3)
integral clamps for non-metallic
cable. Rated for (8) #12 thru branch
circuits. Wago® type push wire
connectors for field connections.
Thermal Protector
Self-resetting thermal protector
protects against improper lamping
and direct contact with insulation.
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.
