What is a LED Ballast?
Electronic Ballasts or Electronic Drivers are used to to carry the various loads required to operate LED, fluorescent, and high intensity discharge bulbs. A ballast works as a transformer to regulate the electrical current of power in a light bulb and light fixture. Ballasts vary in function and capability but without a ballast the electrical current would be unregulated and would rapidly increase its voltage power and draw. Most times when a fluorescent bulb is flickering it is due to a bad or failing ballast.
