Dimmable Electronic Fluorescent Ballasts

Dimmable fluorescent ballasts are compatible with dimming switches and lighting controls that turn lights on or off and allow the light output to be dimmed. They are used in fluorescent lighting fixtures in conference rooms, schools, and other areas where lights will occasionally be lowered for presentations or to conserve energy. Dimming ballasts and lighting controls must use the same dimming method and dimming type in order to work together. Ballasts protect 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 and protect them from power fluctuations. Replacement ballasts should have the same voltage and start type as the old ballast, be able to power the number and type of lamps that are used in the fixture, and be capable of fitting into the fixture.
