CORELITE
DESCRIPTION
The Corelite Class R2R Retrofit is designed to replace the core "lighting
engine" of dated and inefficient recessed luminaires, while leaving the
existing metal luminaire body intact. The total watts per luminaire can be
reduced between 30 and 40 percent while improving the overall lighting
quality and visual character of the interior space. The Class R2R is extremely
low in profile with a 3" overall height, allowing for retrofit of shallow 3"
lensed troffers. In addition to the energy cost reduction and improved
lighting conditions, the Class R2R's 80%+ luminaire efficiency meets the
requirements of many major rebate programs across the US.

SPECIFICATION FEATURES
Construction
Three-piece retrofit assembly
consists of a ballast/bracket
assembly, reflector and lens.
Ballast/bracket assembly and
reflector each have captive
zinc-plated self-drilling hardware.
Mounting brackets are pre-paint
white 20-gauge die-formed steel.
Reflector is one piece die-formed
aluminum with a matte white
powder coat painted finish. Ballast
is pre-wired to factory installed
sockets on each mounting bracket
with the ballast/bracket assembly.
3" low-profile assembly will retrofit
into both parabolics and troffers.
Finish
Reflector is matte white powder
coat painted finish. Ballast brackets
are pre-paint white with white
semi-gloss finish.
Electrical
Ballast is fully tested and pre-wired
to factory installed sockets within
the ballast/bracket assembly, and
comes with captive self-drilling
hardware and integral quick
disconnects. T5/T5HO fixtures use
UL listed Class P, T5/T5HO
program rapid start universal
voltage electronic ballasts, with
pre-installed quick disconnect.
Standard Ballast Factor of 1.0 and
Power Factor of 98%.
Mounting
First, existing lamps, reflectors,
lenses, ballast covers, ballast and
socket trays must be removed
from existing luminaire. Next, the
ballast/bracket assembly is
installed by first mounting the
ballast to the top of the existing
luminaire, then by attaching the
mounting brackets. The reflector
then mounts to the ballast/bracket
assembly, and finally lamps and
lenses are installed.
Shielding
Luminaire lens is UV resistant
acrylic with an optically designed
prism structure, which diffuses
lamp image and provides high
light transmission and luminaire
efficiency (80%+).
NOTE: Fit Compatibility
Retrofit kit fits most troffers. The
end-user is responsible for
verifying fit. Therefore, a sample
kit is highly recommended.

FIT COMPATIBILITY GUIDELINES
The Class R2R is an extremely low profile retrofit design and will fit the majority of existing lensed troffers and louvered parabolics. However, Corelite cannot guarantee
fit with every existing luminaire – fit confirmation is therefore the responsibility of the end-user. For best results, contact your local representative for a sample or trial
installation prior to ordering.
