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.

Our lamp isolators give the designer the ability to create three light levels by isolating uplight and downlight combined
with dual circuit wiring. During the design process, the direction of each lamp must be specified with a simple
designation that indicates whether the lamp is oriented "up", "down" or not at all. The kit consists of one, two or three,
formed aluminum removable optical shields per 4' section of luminaire.
