CORELITE
DESCRIPTION
Whether new construction or retro-fit, the Class E series from Corelite
provides a simple, versatile solution in a sleek architectural package. In a
budget conscious environment, the E3 design, with a fully uniform and
luminous lens aperture, opens up new aesthetic possibilities where the
typical economy luminaires fall short. By incorporating a highly
transmissive lens and a proprietary reflective film, the E3 provides luminaire
effiencies above 80% in most lamp configurations. The Class E3 has a
hinged door frame design and 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
