Electronic Fluorescent Ballasts
Electronic fluorescent ballasts can replace burnt-out electronic or magnetic ballasts in fluorescent lighting fixtures. They are more efficient than magnetic ballasts and do not hum or cause lights to flicker. These ballasts are compatible with switches, occupancy sensors, and other lighting controls that turn lights on or off but do not dim their light output. Electronic ballasts protect light bulbs from damaging power fluctuations that can reduce the quality of the bulbs' light output. They provide an initial spike of high voltage to turn on light bulbs and then regulate the current to the bulbs for as long as they are on. Replacement ballasts should have the same voltage and start type as the old ballast, be able to power the number and type of bulbs that are used in the fixture, and be capable of fitting into the fixture.
