Electronic ballast for one to four lamps

The Fulham WH6-120-L electronic ballast operates on 120V AC and supports one, two, three or four fluorescent lamps. It is compatible with BX, DBX, T12, T5, T5-Circuline, T6, T8 and T8U bulb types across a wide wattage range. This unit suits installers maintaining or upgrading compatible fluorescent fixtures in commercial or residential settings. It is not intended for LED retrofits or dimming applications.

Instant start with no dimming and cold-weather

The ballast uses an instant start method and provides no dimming function, so light output remains at full level whenever the circuit is energised. It is rated for a minimum starting temperature of -22 degrees F, allowing reliable ignition in unheated spaces such as garages, warehouses or outdoor signage. Power draw will vary with the number and wattage of lamps installed, up to a total of 140 watts.

California Proposition 65 notice included

The product carries a California Proposition 65 warning stating it contains a chemical known to the state to cause cancer and birth defects or other reproductive harm. No additional accessories, mounting hardware or software are bundled with the ballast. Installers should follow local codes and the manufacturer’s wiring diagrams when connecting the supported lamp configurations.

Questions about this item

How do I wire the Fulham WH6-120-L ballast for a single T8 lamp, and which terminal do installers often miss?

Connect the 120V AC supply to the black and white input leads, then run the red and blue output leads to the lamp sockets; the yellow common lead must also be landed, and that is the one most often left disconnected.

What component will need replacement first on the WH6-120-L, and how can I tell?

The electrolytic capacitors inside the ballast degrade over time; when the lamps flicker, start slowly, or fail to strike at the rated -22°F minimum, the capacitors are the likely cause.

What thermal limit stops the WH6-120-L from running continuously at full 140W load?

The internal thermal protection trips when the case temperature exceeds its design limit, which occurs first under sustained maximum-wattage operation with four lamps.
