DESCRIPTION Wall mounted luminaire for outdoor applications where contemporary styling is desired.
HOUSING Cylindrical post top luminaire consists of roof, shade, and external louvers with matching profiles. Four stainless steel upper support rods separate the heavy-duty cast aluminum roof and spun aluminum shade, forming an aperture at the top of the luminaire. Machined lower rods support the shade and retain three spun aluminum external louvers midway along its length. Shade and louvers shall be free from burrs and sharp edges. Heavy-duty cast aluminum base with integral slipfitter anchors the support rods, and is machined to include groove for gasketing and mounting surface for the lens and ballast enclosure. Roof and base are gasketed to provide a weather-tight seal to the clear acrylic cylindrical lens. Luminaire slipfits 2.4" O.D. tenon, and has built-in stop to limit insertion depth to 2.2". Two offset rows of three 10mm recessed setscrews secure the luminaire to the pole. All hardware is stainless steel.
OPTICS Vertical base down lamp is positioned within the clear cylindrical acrylic lens. Three external louvers, painted to match the fixture, shield the lamp at normal viewing angles. Underside of spun aluminum shade and roof are painted white. Optional internal louvers are available for symmetric and asymmetric distributions to provide additional brightness control.
ELECTRICAL

Electrical components are mounted in a conical spun aluminum enclosure at the base of the luminaire. Enclosure is painted white.

Ballast and starter combination shall be capable of reliable starting to -20°F (-30°C) at nominal line voltage of ±10%. Ballast, capacitor, and starter are UL and CSA recognized. Medium base porcelain socket is 660w-600v, 4kV pulse rated.
