For libraries and other environments where strong yet discrete lighting

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.

is required, the Stacklight makes a superior choice.

The Stacklight features color-coded quick connectors to assure fast and proper wiring without the removal of any luminaire compo- nents. 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.
