320W Semi Cutoff Metal Halide Wall Pack

320W Semi Cutoff Metal Halide Wall Pack


Our 320 watt semi cutoff metal halide wall packs are large, durable aluminum fixtures that project brilliant illumination for the relatively low wattage they consume.

320W pulse start metal halide lamps are considered high-intensity discharge (HID) lights. The gas discharge bulb produces illumination from an electric arc. The arc is sparked by an energized gaseous mix of vaporized mercury and metal halides.

Unlike incandescents, which use an inefficient super-hot filament to produce light, MH technology gives you more light for more time. Metal halide is twice as efficient as mercury vapor and HPS lights, and are three to five-times that of incandescents!

Key Features

  • UL Listed for wet locations across the United States
  • Can withstand prolonged cold weather as low as -22° F
  • 2-year warranty

Due to the size of this brute light, the 320W semi cutoff metal halide wall pack is best accustomed to lighting huge areas and paths. MH-320's are a great luminary for recreation areas, walkways, stadiums and parking garages.

These are 100% outdoor lights which can withstand harsh weather, rain, sleet and snow. Rubber gaskets prevent water from precipitation or humidity from interacting with the internal components. Their heavy aluminum and glass design also makes them very difficult to vandalize. 

External Specification

Their housing is built with a tough, die-cast aluminum, with a powder-coated architectural bronze finish. A heat-resistant borosilicate refractor covers the lamps inside. Rubber gaskets seal the unit completely from outside moisture. 

MH-320's have 1/2" conduit entry points at the bottom for vertical surface mounting. Conduit points in back facilitate attachment to any 4" j-box.

Internal Specification

The 320 watt pulse start metal halide lamp screws into a mogul-based 4KV glazed porcelain socket. An anodized aluminum reflector behind the lamp focus and intensifies the projected light while keeping the rear circuitry protected from the white-hot light.

A CWA ballast regulates the incoming AC power into a voltage acceptable to excite the metal halide elements in the tube.

Electrical Specification

This unit can toggle between 2 wire inputs:

    • Single-tap 480VAC
    • Multi-tap for 120/208/240/277 VAC


Photocontrol Photocell - Sensor detects sunrise and sunset and automatically activates the light accordingly. Select 'PC1' for 120V photocontrol. Select 'PC2' for 208-277V photocontrol.

Full Cutoff Shield - Narrows the wall pack's beam into a focused spot on the ground and prevents light from trespassing into other property or into the sky.

Wireguard - Offers further protection against vandalism.

Polycarbonate guard - a clear shell that encases the entire unit, adding further protection against the elements.
