Ceramic 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 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. Medium base porcelain socket is 660w-600v, 4kV pulse rated.

Inverted tapered steel pole is manufactured from cold drawn over mandrel, electric-weld, mechanical round steel tubing with nominal wall thickness of 0.157”. Flush mounted handhole cover is plasma cut with kerf not to exceed 1/8” and includes triangular tamper-resistant locking device. Circular collar welded at the base of the pole provides transition between the round beveled flange plate and pole shaft. Tenon mounting plate, welded inside the pole top, is drilled and tapped to accept fasteners for securing the tenon. Precision-machined aluminum 3” O.D. tenon fastens to top of pole with three socket head cap screws. Pole is hot-dip galvanized with coating inside and out, then lightly sanded prior to painting. Specify 7.5’ or 10.4’ overall nominal pole height. Pole mounts to anchor base plate assembly with four M12 x 20mm stainless steel socket head cap screws and washers. See pole data sheet for mounting details.

Anchor base assembly consists of four ½” x 15” x 3” hot-dip galvanized anchor rods secured to galvanized steel mounting plate and embedded as an assembly in concrete foundation (by others).
