Cylindrical pendant mounted 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. Lower support rods terminate in two aluminum lens rings, machined to include groove for gasketing and and mounting surface for the cylindrical and bottom acrylic lenses. Roof and lens rings are gasketed to provide a weather-tight seal to the clear acrylic cylindrical lens. Luminaire mounts to bracket with threaded brass nipple and is locked in place with recessed setscrews on the bracket and luminaire roof. All hardware is stainless steel.
Vertical base up lamp is positioned within the clear cylindrical acrylic lens. Three external louvers shield the lamp from normal viewing angles and minimize brightness. Underside of spun aluminum shade and roof are painted white to increase efficiency. Bottom lens is matte acrylic. Optional internal louvers are available for symmetric and asymmetric distributions to provide additional brightness control.
Electrical components are mounted in a conical spun aluminum enclosure at the base of the luminaire. Enclosure is painted white. Consult factory for quick disconnect ballast pod option. Metal halide core and coil ballast with class "H" (180°C) insulation system shall have a minimum high power factor rating of 90% and nominal ballast factor of 1.0. Ballast shall be capable of reliable starting to -20°F (-30°C) at nominal line voltage of ±10%. Ballast and capacitor are UL and CSA recognized. Mogul base porcelain socket for 200w pulse start metal halide is 1500w-600v, 4kV pulse rated. Medium base porcelain socket for 150 ceramic metal halide is 660w-600v, 4kV pulse rated.

Stepped steel pole is manufactured from cold drawn over mandrel, electric-weld, mechanical round steel tubing with nominal wall thickness of 0.142". Pole shall show no seam along shaft. Flush mounted hand hole cover is plasma cut with kerf not to exceed 1/8" and includes triangular tamper-resistant locking device. Pole is hot-dip galvanized with coating inside and out, then lightly sanded prior to painting. Base cover is one-piece 0.080" spun aluminum and finished to match the pole. Specify 16' or 21' overall nominal pole height.
Fabricated steel bracket assembly is available in single or twin configurations. Upper shaft of the bracket assembly is sized to match the upper pole shaft, and is welded to the top of the slip fitter. Slip fitter insertion depth is 7.87". Slip fitter has two rows of four 8mm stainless steel setscrews to secure bracket to the pole. Steel rod with sleeving is welded to the top of the bracket assembly and serves as a wireway to supply power to the luminaire. Sleeving has radiussed inside edges to prevent damage to wiring. Steel rod terminates in fabricated steel luminaire attachment point. Two horizontal angled steel bars are welded to the attachment point and slip fitter. Bracket is hot-dip galvanized with coating inside and out, then lightly sanded prior to painting. Bracket assembly ships prewired with fish-tape.
Housing is cleaned ultrasonically prior to painting. Standard finish is finely textured matte silver grey metallic or black. Special colors available on request.
