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.

C orelite's lates t innovation, S lide-N-Lock optics , revolutionizes the concept of variable uplight and downlight
percentages within a direct-indirect fluores cent luminaire. S lide-N-Lock optics cons is ts of two s liding parts
des igned to provide combinations of uplight and downlight in approximately 5% increments . T he uplight range
begins at approximately 5% (fully clos ed) and ends at approximately 40% (fully open). T he optics will be factory
s et to the s pecified s etting, although it can be field adjus ted. T o adjus t, s imply depres s the control notch, then
"s lide-n-lock" the optic into the des ired s etting. T he S lide-N-Lock optics s imply s lides in and out of the top of the
Navigator II hous ing for eas y lamp maintenance.
