Tanella’s dramatic theater style day form adds architectural impact to any large-scale site. The individual luminaires are punctuated by decorative satin anodized rings encircling a clear acrylic body nested with a fabricated slotted aluminum shroud. The luminaire housing is illuminated from within by a secondary light source in static white or monochrome blue, green, or red LEDs to cast a subtle glow which accentuates the luminaires at night. Primary optics for general illumination include a choice of spot, medium, or wide beam distributions in a choice of color temperatures. The wishbone pole adds both function and dramatic aesthetics as a structure. All steel is hot dip galvanized before being finished in finely textured paint. Pole ships prewired with fish tape for easy luminaire installation. All hardware is stainless steel.

The Tanella I lighting system allows for vertical aiming adjustment of the luminaires, while the Tanella II system allows for both horizontal and vertical aiming adjustment of each luminaire.

Three luminaires of identical construction mount to saddle brackets integral to pole structure. Luminaire housing consists of a slotted cylinder fabricated from 6082 aluminum welded to the machined aluminum ballast enclosure above. Machined aluminum cover is secured to the ballast enclosure with three captive stainless steel socket head cap screws and sealed with one-piece closed cell silicone gasketing. Clear acrylic cylindrical lens with blue film mounts inside the slotted housing, providing colored accent when illuminated. Decorative spun aluminum satin-anodized rings encircle the slotted housing and are attached with blind rivets to provide a floating appearance. Two vertical aluminum struts welded to either side of luminaire act as wireway for power to luminaire. Cable entry on side of enclosure is sealed with weather-tight bushing. Luminaires are vertically adjustable and may be installed facing forward or backward to the pole structure. Luminaires 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.

Spot Distribution:
150w T6 ceramic metal halide - CDM150/T6/830
70w T6 ceramic metal halide - CDM70/T6/830

Flood Distribution:
150w ceramic metal halide - MHC150/U/M
70w ceramic metal halide - MHC70/U/M

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 hand hole 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 hotdip galvanized with coating inside and out, then lightly sanded prior to painting. Nominal pole height is 32'. Pole ships pre-wired with fish tape.

Standard finishes are finely textured matte silver grey metallic, dark grey, graphite grey, matte black, or dark bronze. Special colors available on request.
