Fulham WH22-120-L Electronic Ballast

The Fulham WH22-120-L is an electronic fluorescent ballast designed for traffic and parking lot lighting installations. It operates on 120V AC input and supports one or two compact or linear lamps. The unit handles bulb wattages from 12 W up to 30 W across CFQ, CFT, DBX, T12, T5, T5-Circuline and T8 bulb types. It uses instant start with no dimming capability.

Installation and common issues

Wiring follows standard instant-start ballast practice with line voltage on the input side and lamp holders on the output side. The ballast mounts via its integral feet or tabs inside a suitable fixture enclosure. A frequent error is exceeding the maximum supported bulb wattage or using an unsupported bulb type, which can cause premature failure. Cold-weather starting is rated down to -22 degrees F, so colder environments may need a different model.

Compatibility checks before ordering

Confirm that your fixture uses one of the listed bulb types and that each lamp falls within the 12 W to 30 W range. Verify the supply voltage is 120V AC and that dimming is not required, as this ballast provides no dimming function. Ensure the mounting footprint fits the existing housing and that the operating temperature stays above -22 degrees F. Check local regulations for Proposition 65 compliance if applicable.
