CORELITE
DESCRIPTION
Whether new constructions or retro-fit, the Class E series from Corelite
provides a simple, versatile solution in a sleek architectural package. In
retro-fit applications the E3R is designed to replace the core lighting engine
of dated inefficient luminaires. With identical performance and aesthetics,
the E3R cannot be distinguished from the E3 once installed allowing for
correspondent installations in both new and retro-fit applications. The
hinged door frame design of the Class E3R provides excellent lumen
transmission while providing tool-less and safe maintenance access with
numerous configurations achieving a minimum of 80% luminaire efficiency.

SPECIFICATION FEATURES
A ... Construction
Low profile housing constructed of
die-formed 22 gauge cold rolled
steel with integral 20 gauge socket
tray.
E ... Finish
Fixture housings are high
reflectance white using
electrostatically applied polyester
powder coat paint.
B ... Reflectors
Precision tooled, high reflectance
sheet metal which allows for easy
access to ballast compartment.
Mounting
Standard flange design works with
most lay-in ceiling types. Integral
pryout tabs secure luminaire to
ceiling grid from above. Fixture
offers tie-in locations for tie-wire
on all corners, consult local code
for appropriate tie-wire
recommendations.
C ... Shielding
Hinged door frame with extruded
acrylic optic. Door frame provides
tool-less access to lamps with
spring loaded latching system.
NOTE: Concealed Ceiling
Class E may be installed into
inaccessible ceilings (sheet rock,
wood panel, etc.). This is achieved
with the Metalux DFW series
drywall frame-in kit, ordered
separately from Metalux. Specify
CC for the Corelite Ceiling Type.
Specify the following part numbers
separately, from Metalux: For 2x2,
order Metalux part # DF-22W
