What are Electronic Ballasts?
Ballasts limit the amount of current from supply line voltage, while maintaining the necessary electrical conditions for proper lamp start and operation. Ballasts vary in design complexity. Older, simplistic magnetic models minimally include inductors, capacitors and a series resistor. Modern electronic ballasts employ solid-state circuitry, which successfully eliminates the stroboscopic effect of flicker in fluorescent lighting, while increasing ballast efficiency.
Electronic ballasts, or drivers, are used to drive various lighting loads, including light emitting diodes (LED), fluorescent (Linear and CFL), induction fluorescent (IF), and high-intensity discharge (HID) lamps. These designs have different electrical start-up characteristics that ...read more
