Fulham WorkHorse 3 120V Ballast

The Fulham WorkHorse 3 WH3-120-C is an instant start electronic ballast designed for 120V AC input. It operates fluorescent lamps in Type 1 and Type 2 outdoor locations. The unit features side exit leads and a stainless steel finish. It is listed cULus Class P and carries a five year manufacturer warranty.

Suitable Installations and Limitations

This ballast suits installers needing reliable instant start operation down to -22 degrees Fahrenheit. It supports one or two lamps from a wide range of wattages including T5, T6, T8, T10 and T12 types. Buyers requiring dimming capability should look elsewhere as this model provides no dimming function. It is also not intended for input voltages other than 120V.

Lamp Compatibility Range

The ballast supports a broad selection of fluorescent bulb wattages from 12W up to 100W across types BX, DBX, T5, T6, T8, T10, T12 and T12U. Matching the lamp type and wattage to this supported list is the single specification that decides whether this is the correct part for the fixture.

Questions about this item

How often should the Fulham WorkHorse 3 WH3-120-C ballast be replaced under normal use?

The ballast carries a 5 year manufacturer warranty. Electronic ballasts typically run for many years beyond that period; plan to replace it if lamps flicker, fail to start, or the unit becomes excessively hot.

What is the first limit reached when the WH3-120-C runs continuously at full load?

The ballast supports a maximum of 100 W across one or two lamps. Exceeding that wattage will trigger its internal protection before any thermal limit is reached.

How much heat and noise does the WH3-120-C produce during all‑day operation?

The instant‑start electronic design runs silently with no fan. Normal surface temperature stays warm to the touch; the stainless‑steel case helps dissipate heat in Type 1 and 2 outdoor locations.
