FEAT URES ORDERING INFORMATION NOTES
OPTICAL SYSTEM
• Self-flanged, semi-specular or matte-diffuse lower reflector in combination with
highly reflective/diffuse upper reflector provides unparalleled performance and
efficiency. Patented Bounding Ray™ Optical Principle design (U.S. Patent No.
5,800,050) provides source before source image and smooth transition from top
of the reflector to bottom.
• Outer kicker reflector with inner reflector provides uniform wallwash performance from ceiling to floor and fixture to fixture.
• Wallwash trim orientation is independent of housing, eliminating installation
concerns.
MECHANICAL SYSTEM
• Housing accommodates a maximum 1-1/2” ceiling thickness.
• Light engine and driver are accessible from above or below ceiling and can be
upgraded to accommodate future technology improvements.
• 16-gauge galvanized steel mounting bars with continuous 4” vertical adjustment are shipped pre-installed. Post installation adjustment possible without
the use of tools from above or below ceiling.
• Galvanized steel junction box with hinged access covers and spring latch. Three
combination 1/2”-3/4” and one 1/2” knockout for straight-through conduit runs.
Capacity: 8 (4in, 4out) No. 12 AWG conductors rated for 90°C.
• Secondary housing adjustment system for precise, final ceiling to flange
alignment.
