• High ef ciency recessed 1X4  uorescent luminaire featuring a custom designed frosted acrylic light shield that transmits more light than perforated metal shields. Frosting and in- ternal ribs hide lamp imaging while providing the soft direct illumination. An optically correct double arched re ector enables precise indirect light distribution.
• The system delivers comfortable illumination by  lling the en- tire 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 ceil- ing 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 blended 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 coat- ing is applied to the re ector and the housing after fabrica- tion. Provides a re ectivity of at least 90%.
• T5 Lamps: Two or three 4ft. linear  uorescent lamps; 28W-T5 or 54W-HO-T5.
• T8 Lamps: Two 4ft. linear  uorescent lamps; 32W-T8. Others as speci ed.
• TT5 Lamps: Two or four 2Ft. twin-tube compact  uorescent lamps; 40W-TT5, 50W-TT5, or 55W-TT5, end-on-end down the center.
