SPECIFICATIONS:
• Ultra shallow recessed 2X4  uorescent luminaire featuring a computer designed precision optical system that provides indirect/ direct illumination. An optically correct double arched reflector en- ables precise indirect light distribution. A center mounted drop- down 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.
• All components are recessed above the ceiling line except the drop-down light shield, which protrudes down 1-7/8".
• 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 support clips are located on the sides.
• Indirect re ector: Two-piece system is CAD designed to the op- ti-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.
• Centerlightshield:Dieformedandfabricatedfromheavygauge perforated steel and integrated with an internal white Mylar panel. Light shield is capable of swinging down for lamp access.
• Finish:Acustomformulatednon-glarewhitepowdercoatingis applied to the re ector, light shield, and the housing after fabri- cation. Provides a re ectivity of at least 90%.
• T5Lamps:Two4Ft.linearfluorescentlamps;28W-T5or54W-HO-T5.
• TT5 Lamps: Four twin-tube compact  uorescent lamps; 40W-TT5, 50W-TT5, or 55W-TT5.
