OPTICAL SYSTEM

• Self-flanged, semi-specular or matte-diffuse reflector. Patented Bounding Ray™
Optical Principle design (U.S. Patent No. 5,800,050) provides lamp before
lamp image and smooth transition from top of reflector to bottom. Minimum
flange matches reflector finish.

• Patent-pending integrated snoot and optical system minimizes lamp striations
normally associated with PAR lamps and creates visually pleasing scallops on
vertical surfaces.

HOUSING

• Heavy gauge, aluminum housing with weather-sealed upper lens for clean
appearance. Matte white textured polyester powder paint finish standard.
