Metal halide to LED conversion chart

Electrical contractors often need a quick metal halide to led conversion chart available for reference when making the switch to LED. We at Factory LED Direct have made this quick reference guide for your use when purchasing new LED replacements for metal halide lamps. Metal halide (MH) lamps and fixtures have become one of the most popular choices for a wide range of commercial and industrial lighting applications. Metal halide bulbs with a E39 screw-in base are found everywhere; from industrial high-bay and low-bay fixtures, streetlights, and floodlights, to security lighting, landscape lighting, and even high-wattage recessed spotlights. The MH bulb is characterized by its large size, high watts, and a filament.

Metal halide lamps produce light by sending an electric arc through a pressurized metallic vapor inside the bulb and require a warm-up period of several minutes to reach their full brightness. Metal halides require a ballast to provide high starting voltages and to regulate current inside the bulb during operation. At startup, the ballast acts as a step-up transformer to raise voltage several times greater than the 110-220VAC supply voltage. This is why a metal halide bulb will not work in a standard household lighting fixture.

Most LED products will run on any voltage from 100-277VAC and the technology lends itself to an unlimited number of bulb and fixture designs. LED is more efficient and energy saving than metal halide. Factory LED Direct is here to help with all your LED lighting needs.
