400W Semi Cutoff Metal Halide Wall Pack

400W Semi Cutoff Metal Halide Wall Pack


Our 400W semi cutoff metal halide wall packs are large aluminum outdoor fixtures that project brilliant illumination in the roughest environments. They can operate in temperatures as low as -22° F and feature installed rubber gaskets to keep out water and moisture.

These fixtures have 400 watt pulse start metal halide lamps, which are illuminated by an electric arc rather than a filament like incandescent models. The arc is sparked by an energized gaseous mix of vaporized mercury and metal halides.

These wall units are known in the lighting industry as high-intensity discharge (HID) lights, part of the gas discharge family of lamps. 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 U.S.
  • Can withstand cold temperatures as low as -22° F
  • 2-year warranty

The 400 watt semi cutoff metal halide wall pack is a large, durable fixtures that are a great choice for lighting outdoor parking lots, sidewalks and as beauty lighting for building facades. 

Installing a few of these lights in place of medium or small metal halide units can actually save you time and money, since one of these units will put out an enormous amount of light equivalent to multiple smaller luminaries.

External Specification

MH-400s are constructed with a corrosion resistant die-cast aluminum housing, powder-coated with an architectural bronze finish. A semi-clear borosilicate refractor protects the metal halide lamps inside. Stainless steel fasteners and rubber gaskets seal the unit completely from outside moisture. 

They have 1/2" conduit entry points at the bottom for surface mounts and conduit points in back for attachment to any 4" j-box.

Internal Specification

The 400W pulse start MH tube fits into a pulse rated 4KV glazed porcelain socket. The light they produce is directed and amplified by an internal anodized aluminum reflector.

A HX-HPF ballast converts incoming AC power into a voltage applicable to the metal halide tube and regulates any sudden overloads. Ballast can survive in temperatures as low as -22° F.

Electrical Specification

This unit can toggle between 2 wire inputs:

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


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 - Further protection against vandalism.

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