• Recessed 2X4  uorescent luminaire featuring a computer designed precision optical system that provides indirect/ direct illumination. An optically correct arched re ector enables precise indirect light distribution, while a narrow four-inch wide center located perforated light shield provides the soft direct illumination.
• 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.
• 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 is CAD designed to the optimum contour. Held in place with quarter turn cam locks for easy ballast access.
• The narrow center light shield is die formed and fabricated from heavy gauge perforated steel and integrated with an internal white Mylar panel. Light shield is capable of swinging down for lamp access.
• A custom formulated non-glare white powder coating is applied to the re ector, light shield, and the housing after fabrication. Provides a re ectivity of at least 90%.
