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 slip fitter 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 slip fits 3" O.D. pole or tenon, and has built-in stop to limit insertion depth to 3.5". Two offset rows of three 10mm recessed setscrews secure the luminaire to the pole. All hardware is stainless steel.
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 components are mounted in a conical spun aluminum enclosure at the base of the luminaire. Enclosure is painted white. Optional quick disconnect for tool-less replacement of ballast pod available on request.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 seamless mechanical tubing with nominal wall thickness of 0.1426. 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.
Stepped aluminum pole is manufactured from extruded 6061-T6 aluminum alloy. Upper shaft is 3" OD with 0.188" wall thickness. Lower shaft is 4.5" OD with 0.237" wall thickness. Machined aluminum transition is plug- and circumferentially welded to both shafts. Flush mounted hand hole cover is plasma cut with kerf not to exceed 1/8" and includes triangular tamper-resistant locking device.
Base cover is one-piece 0.080" spun aluminum and finished to match the pole. Nominal pole height is 10' overall with 3' step; or 12' or 14' overall with 4' step.
Twin mount bracket assembly is fabricated from steel, then hot-dip galvanized. Slip fitter has inner steel sleeve which acts a stop to limit insertion depth to 7.8". Assembly slip fits 3.25" O.D. pole and is secured with two rows of four 10mm stainless steel setscrews. Twin pairs of parallel square steel tubing are welded to connect the slip fitter to the individual tenons for fixture mounting. Bracket assembly ships pre-wired 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.
