Ballasts & Drivers
Ballasts and drivers install into lighting fixtures to regulate current and voltage flowing to the fixtures' light bulbs or LED arrays. They protect light bulbs and LED arrays from damaging fluctuations in the power supply that can reduce the quality of the bulbs' and arrays' light output. Fluorescent ballasts and HID ballasts turn on fluorescent or HID light bulbs with an initial spike of high voltage and then regulate the current to the bulbs for as long as the fixture is turned on. LED drivers convert high-voltage alternating current (AC) into low-voltage direct current (DC) to power LED light bulbs and fixture arrays.
