• Ultra shallow recessed 2X4  uorescent luminaire featuring a computer designed precision optical system that provides indirect/direct illumination. An optically correct double arched re ector enables precise indirect light distribution. A hybrid light shield, perforated sides with a straight cross blade louver down the center, provides the soft direct illu- mination.
• 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. Engineered for shallow plenums.
• Housings are 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 supports are located on the sides.
• The indirect re ector, CAD designed to the optimum contour, is a two-piece system. 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.
• The center hybrid light shield is 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.
