CORELITE
DESCRIPTION
Corelite's Iridium Perf suspended semi-indirect fluorescent luminaire
features elegant styling with sleek profile end caps. 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. Iridium may be mounted
individually or continuously with 4', 8' and 12'modular sections. Luminaires
align with T-Grid and interface with all ceiling types. Iridium is suited for
opens offices, private offices, conference rooms, corridors, schools,libraries,
labs and public spaces.
