SPECIFICATIONS:
• High efficiency ultra-shallow recessed 2X4 fluorescent luminaire featuring a custom designed frosted acrylic light shield that transmits more light than perforated metal shields. Frosting and internal ribs hide lamp imaging while providing the soft di- rect illumination. An optically correct double arched re ector enables precise indirect light distribution.
• Fixtureef cienciesexceed86%astestedwithtwo54W-HO-T5 lamps. This computer designed precision optical system quali es for many state and national rebate programs.
• 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 fab- ricated in a computer-controlled operation. Spot-welds and rivets hold all parts together for strength and unity. Pry-out style grid supports 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 light shield: Extruded with internal linear ribs from 100% acrylic with an added colorless frosting blend- ed into the material. Allows maximum light transmission for higher  xture ef ciencies while hiding lamp imaging. 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 and the housing after fabrication. Provides a re ectivity of at least 90%.
• T5 Lamps: Two or three 4ft. linear  uorescent lamps; 28W-T5 or 54W-HO-T5.
