CORELITE
DESCRIPTION
Corelite's Class A Perf D/I suspended direct-indirect fluorescent luminaire
combines classic design with an additional direct component via center
downlight apertures. The engineered optical system provides a widespread
uplight distribution for excellent ceiling uniformity and wide row spacing.
The perforated fixture housing creates a soft downlight component to
closely match the ceiling brightness, which minimizes contrast on computer
screens. Class A Perf D/I may be mounted individually or continuously with
4', 8' and 12' modular sections. Luminaires align with T-Grid and interface
with all ceiling types. Class A Perf D/I is suited for open offices, private
offices, conference rooms, corridors, schools, libraries, labs and public
spaces.
