A High Pressure Sodium (HPS) Ballast is an electrical device that regulates the current and voltage for HPS lamps. It ensures proper lamp ignition and stable operation by controlling the electrical flow once the lamp is lit. These ballasts are essential for the efficient functioning of HPS lights, which are commonly used in street lighting, parking lots, and industrial settings. HPS ballasts are typically available in magnetic or electronic types, with electronic versions offering higher energy efficiency and quieter operation.
