Fluorescent Ballasts

Fluorescent ballasts install into compatible lighting fixtures to protect linear fluorescent and CFL lamps from damaging power fluctuations that affect the lamp's output quality. They provide an initial voltage spike to turn on the lamps, then regulate the voltage and current. Electronic fluorescent ballasts replace failed electronic or magnetic ballasts in fluorescent lighting fixtures. They are more energy efficient than magnetic ballasts and do not hum or cause flickering. Dimmable electronic fluorescent ballasts are compatible with lighting controls that allow a fixture's light output to be dimmed. Magnetic fluorescent ballasts replace burnt out magnetic ballasts in older fixtures. Fluorescent sign ballasts power high-output fluorescent lamps in indoor and outdoor signs. Fluorescent light starters pair with ballasts, generating a discharge that lights the lamp. Ballast accessories maintain or improve the function of fluorescent ballasts.
