4 Lamp T8 Ballasts
Instant Start vs. Programmed Start
Not sure which type of T8 fluorescent ballast you need? Instant start and programmed start ballasts are both great technologies, but they are intended for different applications.
Quickest, most energy-efficient, instant-on lighting intended for areas with infrequent switching and "on" cycles of several hours. Ideal for offices, warehouses, and retail spaces.
Programmed (Rapid) Start
Slower starting, energy-efficient lighting that prolongs the life of lamps and performs well in frequently switched applications or in areas controlled by an occupancy sensor. Ideal for hallways, stairwells, and bathrooms.
