DESCRIPTION
The next generation addition to the Iridium family, the direct-indirect i2
series, offers a generous open center aperture for maximum versatility in
optics, lamping and distribution. The i2 is also available with adjustable
uplight and downlight optics for evolving interior spaces with Corelite's
Slide-N-Lock (TM) optics accessory. i2 may be mounted individually or
continuously with 4' and 8' modular sections. Luminaires align with TGrid and interface with all ceiling types. The i2 is ideally suited for open
offices, conference rooms, classrooms, libraries, labs and public spaces.
