louvers Cast Aluminum Louver blades provide sharp cutoff providing no direct light above 90°. Louvers are secured to the shaft via tamper resistant stainless steel rods and fasteners. lamp enclosure Lamp enclosure is one-piece tempered glass with internal flutes for even disbursement of illumination. Decorative colored glass optional. Globe is fully gasketed via EPDM material. Socket is porcelain, medium-base for HID lamp sources. lower housing Nominal 1/8" thick extruded aluminum housing. Bollard housing is secured to the base with flathead, counter-sunk screws for smooth, uncluttered appearance. Electrical High Power Factor ballast for –20°F starting. Product is factory mounted to the base. Quick disconnects provided between lamp and electrical assembly. Metal Halide and High Pressure Sodium lamp sources up to 100W Metal Halide or High Pressure Sodium coated lamps. finish Premium fade and abrasion resistant, TGIC Polyester Powder Coat Finish. Standard colors are Bronze, Architectural White, Grey and Black. Other architectural finish colors available including all RAL matches. Base Rugged cast aluminum. Completely concealed. Mounting Base mounts onto foundation with three (3) 1/2" x 12" anchor bolts on a 5" Dia. bolt circle (a centrally located 2 7/8" x 3 1/2" wire entrance opening provided). louvered features BSL square louvered series BRL ROund dome top louvered series BSL square louvered series BRL ROund dome top louvered series Standard series—features Top Rugged, cast aluminum. Provides rapid heat dissipation. Encloses the upper reflector so it is hidden from view. Tamper-proof screws provide easy access to lamp compartment. Housing Consists of a heavy-duty, seamless extruded aluminum tube. Lifts off base for easy access to ballast. Optics Lower dispersing reflector, in conjunction with a truncated, octagonal upper collecting reflector, provides low-glare, highly efficient illumination with optimum uniformity. EXAMPLE: Using 70W HPS lamps with Bollard Series luminaires mounted on 20' centers produce a symmetric light pattern with a max. to min. uniformity ratio of less that 4:1. Lens 1/4" wall, impact-resistant clear acrylic. Polycarbonate lens is optional. Prismatic refractor All Bollard Series luminaires are available with an optional prismatic borosilicate glass refractor to provide efficient, low-glare light distribution. Gasketing Bollards are designed to form a single, integral unit that is completely gasketed and sealed from outside contaminant’s. Electrical High Power Factor ballast for –20°F starting. Product is factory mounted to the base. Quick disconnects provided between lamp and electrical assembly. HPS and MH Lamp sources up to 100W MH or HPS and up to 57W Compact Fluorescent sources available with MOLlength not exceeding 7". Finish Premium fade and abrasion resistant, TGIC Polyester Powder Coat Finish. Standard colors are Bronze, Architectural White, Grey and Black. Other architectural finish colors available including all RALmatches. Base Rugged cast aluminum. Completely concealed. Mounting Base mounts onto foundation with three (3) 1/2" x 12" anchor bolts on a 5" Dia. bolt circle (a centrally located 2 7/8" x 3 1/2" wire entrance opening provided). Bollard housing is secured to the base with flathead, counter-sunk screws for smooth, uncluttered appearance. Standard series—features bRc round standard series bsc square standard series bRc round standard series bsc square standard series optical excellence Glare-free illumination The Louver Series bollard features carefully designed louvers that block direct view of the lamp while creating a channel for high angle light to escape and effectively illuminate the pathway below. These duel purpose louvers eliminate glare and provide comfortable fixture viewing without sacrificing performance. UNIFORM ILLUMINATION The Louvered Series bollard features fluted glass refractors to direct light rays around louver support elements, eliminating the potential for unsightly shadows and streaking in the distribution. Coated lamps, in conjunction with the refractive glass lens, allow the Louvered Series bollard to produce uniform illumination. design flexibility Add some flair and personality to your application with the use of optional colored refractive glass lenses. The Louvered Series bollards allow the design flexibility with a selection of highly saturated colors. Producing a blanket of color on the walkway as well as a pronounced glow on louvered surfaces, they feature prismatic refractive technology, ensuring a uniform distribution of color and light. optical excellence side view efficient illumination The McGraw-Edison Standard Series bollard locates the lamp in the housing top cap preventing direct viewing of the lamp at pedestrian and motorist level. The multi-piece reflector system works in unison to maximize efficiency by redirecting otherwise unuseable light onto the lower reflector which focuses light onto the pathway. top view Optical C...
