SPECIFICATION FEATURES
Lower Shielding Reflector
Painted die cast aluminum or
anodized aluminum lower reflector
with a lensed upper optical
chamber providing superior
lumen output with minimal source
brightness. Anodized reflectors
are offered in all Portfolio Alzak®
finishes. Available with non-
conductive polymer trim. Reflector
is retained with two torsion springs
holding the flange tight to the
finished ceiling surface. Plaster
lathing ring accessory offered for
flush reflector transition.
Plaster Frame / Collar
Galvanized steel plaster frame with
adjustable collar adjusts for up to
2” thick ceilings and rotates+/- 7.5°.
Universal Mounting Bracket
Accepts 1/2” EMT, C channel
and bar hangers and adjusts 5”
vertically from above and below
the ceiling.
Junction Box
(4) 1/2” and (2) 3/4” trade size
pry outs positioned to allow
straight conduit runs. Listed for
(8) #12 AWG (four in, four out)
90°C conductors and feed thru
branch wiring and push in lever
connectors.
Thermal
Aluminum heat sink conducts heat
away from the LED module for
optimal performance and long life.
LED
Chip on board with a multitude
of highly efficient white LED’s,
combined with a high reflectance
upper reflector and convex
transitional lens produce even
distribution with no pixilation.
Rated for 50,000 hours at 70%
lumen maintenance. Auto
resetting, thermally protected,
LED’s are turned off when safe
operating temperatures are
exceeded. Color variation within
3-step MacAdam ellipses. Quick
disconnect allows for tool-less
replacement of LED engine from
below ceiling. Available in 80, 90
or 97 CRI.
D2W™ – dim-to-warm shifts CCT
from 3000K to1850K as fixture dims
mimicking halogen sources.
W2N - Tunable white CCT range
2700K to 6500K or 2000K to 5000K,
90 CRI.
Driver
Standard 120-277V 0-10V
dimming driver provides flicker
free dimming from 100% to 1%.
Optional 120-277V phase dimming,
<1% 0-10V, Fifth Light, DMX or
Lutron® Ecosystem. Driver can be
serviced from above or through the
aperture.
Connected Lighting Systems
WaveLinx tilemount daylight
sensor includes control module,
sensor and cable allowing use
with the comprehensive lighting
system.
LumaWatt Pro (powered by
Enlighted) wireless tile mount
sensor and relay accessory enables
wireless control using a tile mount
sensor accessory.
Distributed low voltage power
system combines power, lighting,
and controls with ease of
installation.

Square Downlight
New Construction
4 inch LED square recessed downlight designed for glare free,
even illumination. Featuring a two-stage diffused reflector system
producing smooth distribution with excellent light control and low
aperture brightness. Lumen packages range from 1000 to 6000 with
color temperatures of 2400K, 2700K, 3000K, 3500K, 4000K, and 5000K.
VividTune: Dim-to-warm technology – similar to halogen at full power,
the 3000K LED warms smoothly as dimmed to 1850K creating a rich
warm glow within the space. Tunable white technology - adjust the
color temperature from warm white to cool white while independently
controlling intensity.
