Plusrite Standard Metal Halide Ballast Kit, 5-Tap, 250W

A Standard Metal Halide Ballast is an electrical component used to regulate the current and voltage for metal halide lamps. It ensures proper ignition and stable operation of the lamp by limiting the current once the lamp is lit. These ballasts are typically used in older or standard metal halide systems and are necessary for the lamp to function safely and efficiently. They are commonly found in applications like street lighting, warehouses, and sports arenas.
