CORELITE
DESCRIPTION
Corelite's latest addition to its line of shallow recessed fixtures, the Class R3,
is the ultimate complement to the R1 and R2, offering the ideal combination
of performance and aesthetics. The fully luminous housing of the R3 creates
a high sense of style and superior brightness management, all while
providing low watts per square foot to satisfy the most stringent energy
requirements. To further realize the Class R series' design potential, the
Class R3 is available with a complete palette of lamp options - including T8
and compact fluorescent - and maintains the series' dedication to shallow
plenum applications with a minimal 3-3/4" deep housing.
