Lightolier Lighting Systems

Lightolier Lighting Systems are modular lighting systems that offer a wide selection of
geometric shapes, architectural profiles, scales and finishes.

Built-in louvers with precise 2" spacing offer excellent shielding
and efficient horizontal illumination. Two T8 fluorescent lamps
provide powerful, yet highly economical lighting. The Stacklight
utilizes an electronic ballast on all models, an electronic dimming
ballast is available if desired.

Designed to be mounted individually or linked in continuous rows.
The Stacklight features color-coded quick connectors to assure fast
and proper wiring without the removal of any luminaire compo­nents. A choice of surface, cable or stem mounting is offered. An
adjustable cable device allows adjustment along the entire length of
the cable without cutting or crimping. When it comes to bringing
high quality illumination to libraries and educational environments,
the Stacklight is clearly at the head of the class.
