CORELITE
DESCRIPTION
Corelite's Navigator II suspended direct-indirect fluorescent luminaire
features a rugged aluminum construction, elegant styling, and a new High
Efficiency Louver which offers up to 7% greater efficiency than the standard
cross blade. Our Slide-N-Lock" optics accessory allows the designer to
adjust the amount of uplight and downlight for a particular application. The
Navigator II may be mounted individually or continuously with 4', 8' and 12'
modular sections. Luminaires align with T-Grid and interface with all ceiling
types. The Navigator II is suited for open offices, private offices, conference
rooms, trading floors, reception areas and educational facilities.

Corelite's latest innovation, Slide-N-Lock TM optics, revolutionizes the concept of variable uplight and downlight
percentages within a direct-indirect fluorescent luminaire. Slide-N-LockTM optics consists of two sliding parts designed
to provide combinations of uplight and downlight in approximately 5% increments. The uplight range begins at
approximately 5% (fully closed) and ends at approximately 40% (fully open). The optics will be factory set to the
specified setting, although it can be field adjusted. To adjust, simply depress the control notch, then "slide-n-lock" the
TM
optic into the desired setting. The Slide-N-Lock optics simply slides in and out of the top of the Navigator II housing for
easy lamp maintenance.
