SPECIFICATIONS:
• Surface mounted 1X4 fluorescent luminaire featuring a comput- er designed precision optical system that provides indirect/direct illumination. An optically correct double arched reflector enables precise indirect light distribution, while a center located perforated light shield provides the soft direct illumination.
• The system delivers comfortable illumination by filling the entire volume of space evenly. Broad angle illumination lights walls and vertical surfaces creating a more open and comfortable space.
• Luminaireis5-1/2”deep.
• Optional light shields: A) Hybrid light shield has perforated sides with a straight cross blade louver down the center. B) Frosted acrylic light shield transmits more light for higher fixture efficiencies.
• Housing: Die formed from 20GA cold rolled steel and fabricated in a computer-controlled operation. Spot-welded together for strength and unity with mitered corners.
• Indirect reflector: Two-piece system is CAD designed to the opti- mum contour. One side is securely screwed into the housing with hidden hardware. The other side is held in place with quarter turn cam locks for easy ballast access.
• Center light shield: Die formed and fabricated from heavy gauge perforated steel and integrated with an internal white Mylar pan- el. Optional hybrid shield has additional cold rolled steel blades. Optional frosted acrylic shield is extruded with internal linear ribs and a colorless frosting blended into the material. Light shield is capable of swinging down for lamp access.
• Finish: A custom formulated non-glare white powder coating is applied to the reflector, light shield, and the housing after fabrica- tion. Provides a reflectivity of at least 90%.
• T5 Lamps: One, two or three 4Ft. linear fluorescent lamps; 28W-T5 or 54W-HO-T5.
