OPTICAL SYSTEM
• Three preset distribution patterns allow designers to achieve various design objectives.
• Clear anodized upper reflector and 6-inch self-flanged, semi-specular, matte-
diffuse or specular finishing trim, provide 50° cut-off, optimal efficiency and
glare control while maintaining a smooth beam pattern that is free of hot spots
and striations.
• Protective lamp guard utilizes clear ceramic technology that reduces UV emissions and provides higher heat tolerance and better protection than standard
borosilicate lenses.
MECHANICAL SYSTEM
• One-piece die-cast aluminum housing provides 3 square feet of surface area to
dissipate heat and improve lamp life. Entire housing is coated with black paint
to minimize visibility when installed in open ceiling construction.

hardware is captive.
