About our Fulham Workhorse-7, 277-Volt, Electronic Fluorescent Ballast

The Fulham Workhorse 7 operates fluorescent lamps that include T5 high output, T8, and even T12 lamp types. This Workhorse ballast offers a high power factor with an A sound rating. The ballast is designed with instant start functionality and is most efficient when used in areas where lights are not turned on and off frequently.

  • Versatile: this Fulham electronic fluorescent ballast, WH7-277-L, powers T5 high output, T8 linear, and T12 linear fluorescent. See the full list of fluorescent Lamp Type & Lamp Quantity combinations in the table below.
  • Fulham Workhorse 7 Wiring Diagram: please visit the Fulham Workhorse wiring diagram tool for instructions on how to wire this ballast. First, click on the type of light bulb you wish to power on the left side of the screen. Second, find your ballast model along the top. Third, find the wattage of the lamp combination you will be powering and click on the link to view the matching diagram.
  • Features: solid-state electronics, small case size, high power factor, lightweight, energy saving. Fulham's WorkHorse adaptable electronic ballast family has been a favorite with electrical contractors since 1992. Fewer ballasts on the service truck that can power nearly 900 different lamp combinations saves time and money. The ability of a ballast to accommodate multiple lamp types is a huge time-saver for the person in the field.
