Features
LED Square DL/4-950 is a 4” square downlight employing LED (light
emitting diode) technology. Fixture is only 5
7
/
8
deep and provides a
shielding angle of 40°. Precise reflector design minimizes aperture
brightness and virtually eliminates the inter-reflections inherent with square
apertures. 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 oruorescent
• 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
LED Square DL/4-950 reflectors are available
with optional glass shields for applications
where protection is required by code.
Reflectors are available in slightly diffuse
clear natural aluminum or champagne gold
Alzak
®
. Other reflector finishes are available
on special order.
LED Square DL/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.

Fixture is recommended for downlighting 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 a fire rated
ceiling. Removal of the reflector
allows access to the junction box.

LED Square DL/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.
