Metal Halide Ballasts

An aquarium metal halide ballast powers a metal halide bulb and controls the voltage passing through the bulb.

A magnetic metal halide ballast is an older, less efficient technology, but favored by some for the color it produces in the Radium MH bulb. The modern 150w-400w metal halide electronic ballast is more energy efficient and lasts longer. Many electronic ballasts are selectable, like a 150w-250w metal halide electronic ballast. A selectable 250 metal halide electronic ballast can power a 150w or 250w bulb. Not all metal halide ballasts use the same type of connector. Be sure the ballast plug matches your fixture or be prepared for some basic wiring. Each metal halide ballast will power a single metal halide bulb, unless it is a dual metal halide ballast.
