Lighting ballasts are electrical devices used to regulate and control the electrical current flowing through fluorescent lamps, HID (High-Intensity Discharge) lamps, and other types of gas discharge lamps. They are an integral component of lighting systems, responsible for providing the necessary voltage and current levels to ensure proper operation and illumination of the lamps.
The primary function of a lighting ballast is to limit the current flowing through the lamp and provide the necessary voltage for starting and sustaining the lamp's operation. Ballasts help achieve stable light output, prevent lamp flickering, and extend the lifespan of the lamps.
