IRIS
DESCRIPTION
Recessed 3.5” aperture lens downlight luminaire utilizing a
low voltage MR16 tungsten-halogen lamp. Suitable for 2x10
residential or commercial constructions, airtight and can be
used in direct contact with insulation. Housing platform +
optical element support various lamp beams providing desired
optical distribution with excellent light control and low aperture
brightness. Interchangeable optical elements provide design
flexibility; luminaire can be changed from downlight, to accent to
wall wash.

Frame
Galvanized steel plaster frame
with integral bar hanger receivers.
Setscrews provide positive horizontal
locking. Integral gun sights facilitate
the use of guide strings or laser lines
for accurate positioning. Shipped with
an overspray protector installed.
Housing
Double wall housing provides for
effective thermal management.
Internal housing is painted matte black
for a visually dark interior.
Lamp Capsule
Retained in the adjustment mechanism
with spring loaded ball catches, aim
and focus is not disturbed during lamp
replacement. Ceramic GX5.3 lamp
holder mounts a die cast aluminum
heat sink to dissipate heat and provide
maximum lamp life. Connects to
the transformer with electrical quick
connect. Accepts 2 lenses, filters, or an
optional lamp snoot.
Gaskets
Closed cell gaskets achieve restrictive
airflow requirements without
additional caulking.
Lower Reflector
Spun 0.04” thick aluminum parabolic
contour with integral clear glass lens
provides 60° lens and lens image
cutoff. Available in a wide range of
specular and semi-specular Alzak
finishes. Available with self-flange or
metal trim ring. Light trap eliminates
spill light at edge of trim ring and
reflector. Metal trim ring can be
removed for painting and can be
installed flush mount with optional
flush mount collar accessory. Keyed
to adjustment mechanism preventing
directional trims being installed
incorrectly.
Adjustment Mechanism
Hot aiming rotates 365°, tilts 45° and
locks in position. Angle markings
assist in repeatable settings.
Translating center beam optics aligns
axis of primary reflector with aperture
from nadir to 45°. Shipped set at nadir.
Removable thru aperture for service.
Trim Retention
Retained with two torsion springs
holding the flange tightly to
the finished ceiling surface and
accommodates ceiling thickness from
1/2” - 1” thick. Optional PLE3 plaster
lip extender accommodates up to 2”
thick ceilings.
Bar Hangers
Bar hangers adjust 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 attached directly to tee-bar.
Junction Box
(6) 1/2” trade size pry outs positioned
to allow straight conduit runs. 18 in3
internal volume supports up to (10)
#12 or (14) #14 AWG 90° C conductors
for pass thru or switch legs.
Transformer
Integral magnetic step down
transformer, 120V 50/60Hz input,
12V, 50VA nominal output is greater
than 90% efficient. Toroidal wound
core is epoxy encapsulated providing
extremely low noise and reliable
operation.
P3MR
E3SR
Compliance
Type IC thermally protected, suitable
for direct contact with insulation
and cULus listed for wet locations.
Restrictive airflow per ASTM-E283.
Contains no mercury or lead and
RoHS compliant.

Notes and Formulas:
Luminance: To convert cd/m2 to footlamberts, multiply by 0.2919
Cone of Light:
• Beam diameter is to 50% of maximum footcandles, rounded to the nearest half-foot.
• Footcandle values are initial. Apply appropriate light loss factors where necessary.
See pages 64-65 of Iris catalog
CU Notes/Formulas:
• maintained illuminance= lamp lumens x CU x light loss factors
room area
• total number of luminaires= total room area x maintained illuminance
lamp lumens x CU x light loss factors
• CU data based on 20% effective floor cavity reflectance.
