Intended for use in retail stores, warehouses and manufacturing applications where high lumen package in a compact fixture design is required. Ideal for mounting heights up to 35 feet in controlled ambient facilities. Recommended for climate control spaces.


Channel and louvers are formed from cold-rolled, 20-gauge steel. Designed for simple servicing, louver assembly hinges remain attached and hinge down providing easy access into the optical system. Convenient access plate located on the back of the the channel for easy access to wiring components.

Finish: High-gloss, baked white enamel finish. Five-stage, iron phosphate pretreatment ensures superior paint adhesion and rust resistance.


The Narrow Distribution (ND) includes a parabolic reflector system to provide high vertical and good horizontal illumination for aisle or rack lighting. The Wide Distribution (WD) is ideal for general area lighting at higher mounting heights or where widespread distribution is preferred. Both distributions are available with white straight blade louver for additional shielding and brightness control. Uplight component softens ceiling appearance to reduce the "cavern effect".
