WorkHorse 2 Ballast 277V
The Fulham WH2-277-C WorkHorse 2 is an electronic fluorescent ballast designed for indoor and outdoor fixtures operating on 277V AC at 50 or 60Hz. It supports one or two lamps across a wide range of wattages from 13W to 42W including T5, T6, T8, T8U, T12 and DBX types.
277V Instant Start Limits
The ballast uses instant start circuitry without dimming capability, so lamps ignite immediately but light output cannot be adjusted. It is rated for a minimum starting temperature of -22 degrees Fahrenheit, making it suitable for cold environments. FUSE protection and high power factor operation are built in for circuit safety.
Silver Enclosure with Screw-Down Mounting
A silver metal case measuring 3.40 by 2.30 by 1.00 inches weighs 0.75 lb and carries cULus, FCC Part 18-A, Class P and Sound Rated A listings for Type 1 and 2 outdoor use. Screw-down terminals simplify wiring in junction boxes or fixture channels.

Questions about this item
Should I pick a single-lamp or two-lamp setup with this ballast?
The WorkHorse 2 supports one or two lamps from the listed wattages, so choose the quantity that matches your fixture.
What does the 277 V rating mean when the unit is installed?
It operates on a 277 V AC supply at 50/60 Hz, typical for commercial lighting circuits in North America.
How does the instant-start method affect lamp performance?
Instant start lights lamps without pre-heating, giving faster ignition but slightly shorter lamp life compared to rapid-start ballasts.
