• Features: drop-in replacement for magnetic ballasts, parallel lamp operation, Specifier Grade = THD <10%. 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.
