RAB Lighting VXJ-250-WATT-H37-120-VOLT Ballast

The RAB VXJ-250-WATT-H37-120-VOLT Ballast is a constant-wattage ballast from RAB Lighting designed to drive 250-watt HID lamps with the H37 designation on a 120-volt supply. As part of the VXJ series, it delivers a fixed 250-watt output to compatible luminaires, helping maintain steady light output and predictable lamp operation for the specified lamp type. The model name encodes the essential specifications—250 watts, H37 lamp designation, and 120-volt input—so installers can identify the correct ballast for fixtures that require a VXJ-250 W, 120 V driver. This ballast is intended for installations where a 250 W H37 HID ballast on a 120 V circuit is specified, and it should be paired only with luminaires designed to accept this VXJ-250 W, 120 V configuration. In practice, this means selecting the RAB VXJ ballast when your fixture’s documentation calls for a 250 W H37 HID ballast at 120 V to achieve reliable illumination from compatible HID lamps.
