• Recessed 2X2  uorescent luminaire featuring a computer designed precision optical system that provides indirect/direct illumination. An optically correct double arched re ector en- ables precise indirect light distribution. A hybrid light shield, perforated sides with a straight cross blade louver down the center, provides 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 com- fortable 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-welds and rivets hold all parts together for strength and unity. Pry-out style grid sup- port clips are located on the sides.
• Indirect re ector: Two-piece system is CAD designed to the optimum 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 hybrid light shield: Die formed and fabricated using a combination of heavy gauge perforated steel for each side and standard cold rolled steel for the center cross blades. Integrated with internal white Mylar panels. Light shield is 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%.
• T5 Lamps: Two or three 2Ft. linear  uorescent lamps; 14W-T5 or 24W-HO-T5.
• T8 Lamps: Two or three 2Ft. linear  uorescent lamps; 17W-T8. Others as speci ed.
• TT5 Lamps: One or Two twin-tube compact  uorescent lamps; 40W-TT5, 50W-TT5, or 55W-TT5.
