OPTICAL SYSTEM

• Three preset distribution patterns allow designers to achieve various
design objectives.

• Reflector - Clear anodized upper reflector and self-flanged 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.

HOUSING

white textured polyester powder paint finish standard.

luminaire appearance. Provided with safety chain between reveal and housing
