Fulham WH22-120-C Electronic Ballast

The Fulham WH22-120-C is an electronic fluorescent ballast designed for commercial or residential lighting systems. It operates on a 120V AC input and supports one or two lamps simultaneously. Compatible bulb types include CFQ, CFT, DBX, T12, T5, T5-Circuline and T8. Maximum bulb wattage supported reaches 30 W per lamp.

Instant start thermal performance

This unit uses an instant start method with no dimming capability. The minimum starting temperature is rated at -22 degrees F for reliable cold-weather ignition. Power draw scales with the installed lamp wattage, covering a range from 5 to 35 W total. The ballast weighs 0.35 lb and contains no moving parts, so acoustic output is negligible in normal operation.

Wiring and compliance considerations

Installation requires a standard 120 V supply and appropriate lamp holders for the chosen bulb types. The ballast does not support dimming circuits, so it must be paired with non-dimming switches. California Proposition 65 warnings apply because the product contains chemicals identified by the state as causing cancer and reproductive harm. Builders needing dimming control or higher total wattage should select a different model.

Questions about this item

How do I install the WH22-120-C electronic ballast and what is the step people get wrong?

Connect the 120V AC supply to the input leads and the lamp holders to the output leads matching the wiring diagram for one or two lamps; the step often missed is verifying each lamp wattage is in the 12–30 W supported list before powering up.

What maintenance or replacement will the WH22-120-C ballast need later?

The ballast itself has no user-serviceable parts; plan to replace the CFQ, CFT, DBX, T12, T5, T5-Circuline or T8 lamps when they reach end of life, and inspect wiring connections during lamp changes.

What limit shows up first under sustained use of the WH22-120-C ballast?

The minimum starting temperature of -22 °F is the first environmental limit; below this the instant-start circuit may fail to ignite the lamps reliably.
