deep and
provides uniform illumination on vertical surfaces up to the ceiling line.
Patent pending.
Features of the integral 25-watt, solid-state light engine include
• white colors: nominal 3000°K warm white with a CRI of 85; and
nominal 4700°K cool white, with a CRI of 80
• efficacy: 952 lumens with 3000°K color or 1019 lumens with 4700°K
color – over twice the efficacy of incandescent
• long life: 50,000 hours at 70% output
• emergency lighting option: remote emergency battery pack kit available
– a critical feature for corridors and other circulation spaces
• durability: far more resistant to vibration than incandescent or fluorescent
• operational range: tolerates temperatures as low as –30°C
• thermal efficiency: over 90% of electrical energy converted to light
and virtually no heat projected below
• UV free: no UV emissions to jeopardize fabrics, paper or paintings
• environmentally safe: no mercury to create end-of-life disposal problems
The LED Square WL/4-950 optical
assembly consists of a glass spread lens
mounted atop a four-sided reflector.
Precise reflector design distributes light
to the top of the wall, minimizes aperture
brightness and virtually eliminates the
inter-reflections inherent with square
apertures.
Reflectors are available in slightly diffuse
clear natural aluminum or champagne gold Alzak
®
. Other reflector
finishes are available on special order.
LED Square WL/4-950 includes a pair of mounting bars (¾” x 27” C channel).
Specialty bars for wood joist and T-bar installations are also available.
aPPLICatIONs
Fixture is recommended for wallwashing in commercial, retail and
residential spaces.
Fixture is listed as inherently safe (not
requiring a thermal protector) and
suitable for Damp Location.
Fixture is approved for ten #12
wire 75°C branch circuit wiring
and suitable for use in are
rated ceiling. Removal of the
reflector allows access to the
junction box.

FULLY SUSTAINABLE
LED Square WL/4-950 is fully sustainable. Both critical components
the light engine (diode array) and the driver (power conditioner) – can
be replaced through the aperture with a screwdriver. Both components
are, and will remain, available from Edison Price Lighting.
