• High ef ciency recessed T5  uorescent total volume luminaire featuring an ultra-shallow design and custom formulated frosted acrylic light shield. With a depth of 3-1/8” virtually  ts into any plenum space. Frosted light shield allows maximum direct-light transmission which delivers very high  xture ef - ciencies. Re ector system enables precise indirect light dis- tribution.
• Fixture ef ciencies exceed 83% (as tested with two 28W-T5 lamps) with 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 com- fortable space. All components are recessed above the ceiling line. Install in ceilings as low as eight feet.
• Center light shield: Extruded with internal linear ribs from 100% acrylic with an added colorless frosting blended into the material. Hides all lamp imaging. Light shield snaps in and out for lamp access. Optional perforated steel shield slides over existing acrylic shield when this style is desired.
• Housing:Dieformedfromcode-gradeheavygaugecoldrolled steel and fabricated in a computer-controlled operation. Housing back forms the indirect re ector. Center ballast and wiring cover is removable from below. Rivets and self-locking joints hold all parts together for strength and unity. Pry-out style grid supports are located on the ends.
