Three luminaires of identical constructed mount to brackets integral to pole structure. Slotted luminaire housing is fabricated from 6082 aluminum. Ballast enclosure at top of luminaire is machined aluminum. Ballast cover is secured to enclosure with three captive stainless steel socket head cap screws and sealed with one-piece silicone gasket. Cable entry on side of enclosure is sealed with weather-tight bushing. Two decorative vertical aluminum struts welded to either side of luminaire act as wireway for power to luminaire. Decorative spun aluminum rings with satin anodized finish are attached to housing with concealed hardware providing a floating appearance around the housing. Acrylic cylindrical lens with blue tinting nests within the housing and is sealed on both ends with one-piece EPDM gaskets. Clear polycarbonate lens with UV inhibitors houses the reflector. Lens twists and locks onto luminaire without the use of tools. Individual luminaires mount to saddles on pole structure and are locked into place with clamping mechanism after setting vertical aiming angle. All hardware is stainless steel.

Flood optics use medium base ED-17 lamp with spun aluminum specular reflector, producing wide beam symmetrical distribution pattern. Louver attached to reflector opening minimizes brightness at normal viewing angles.

Spot optics use T6 metal halide lamp with facetted specular reflector, producing narrow beam symmetrical distribution pattern. Louver attached to reflector opening minimizes brightness at normal viewing angles.

Cylindrical lens with blue tinting nested within the slotted housing casts a subtle glow to accentuate the luminaire.

Ceramic metal halide core and coil ballast have class “H” (180°C) insulation system with a minimum high power factor rating of 90% and nominal ballast factor of 1.0. 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. G12 base porcelain socket is 660w-600v, 4kV pulse rated. Medium base porcelain socket is 660w-600v, 4kV pulse rated.

Wishbone pole structure is manufactured from cold drawn over mandrel, electric-weld, mechanical round steel tubing. Pole shall show no seam along shafts. Center pole is 5.5" O.D. with nominal wall thickness of 0.248”. Flush mounted handhole cover is plasma cut with kerf not to exceed 1/8" and includes triangular tamper-resistant locking device. Outer arched poles are 3" O.D. with nominal wall thickness of 0.346". Outer poles are welded to center pole in three places with horizontal crossbars. Additional horizontal crossbars along length of structure are 1.7" O.D. with nominal wall thickness of 0.125" and welded between arched poles. Brackets for luminaire mounting have saddles to support luminaire with clamping mechanisms to secure luminaire in place when vertical aiming adjustment is made. Pole is hot-dip galvanized with coating inside and out, then lightly sanded prior to painting. Nominal pole height is 32’. Pole ships prewired with fish tape.
