SPECIFICATIONS:
• Recessed 2X4  uorescent luminaire featuring a computer designed precision optical system that provides indirect/direct illumination. An optically correct contoured re ector enables precise indirect light distribution, while twin side-located perforated light shields provide the soft direct illumination.
• The system delivers comfortable illumination by  lling the entire volume of space evenly. Broad angle illumination lights walls and vertical surfaces creating a more open and comfortable space.
• All components are recessed above the ceiling line. Install in ceilings as low as eight feet.
• Housing: Die formed from 20GA cold rolled steel and fabricated in a computer-controlled operation. Spot-welded together for strength and unity. Pry-out style grid supports are located on the sides.
• Indirect re ector: One-piece re ector, CAD designed to the optimum contour, is securely screwed into the housing with hidden hardware. Easily removed for ballast access.
• Side light shields: Die formed and fabricated from heavy gauge perforated steel and integrated with an internal white Mylar panel. Light shields are capable of swinging down for lamp access.
• Finish: A custom formulated non-glare white powder coating is applied to the re ector, light shield, and the housing after fabrication. Provides a re ectivity of at least 90%.
• T5Lamps:Twoorfour4Ft.linear uorescentlamps;28W-T5or 54W-HO-T5.
• T8 Lamps: Two or four 4Ft. linear  uorescent lamps; 32W-T8. Others as speci ed.
• TT5 Lamps: Four twin-tube compact  uorescent lamps; 40W-TT5, 50W-TT5, or 55W-TT5.
