High Intensity Discharge (HID) lamps require a ballast to apply starting voltage to the lamp and establish current flow an arc between the lamp electrodes. Without a ballast, the arc will extinguish or draw increasing current until some circuit element burns up. Ballasts provide
system stability by limiting the current that can be drawn. Click here to view our offering of major brand Medium and Mogul Base HPS Lamps.
Core and Coil ballast kits are used in over 90% of all HID lighting. Replacement high pressure sodium (HPS) ballast kits contain the appropriate core and coil, a properly rated ignitor and all components required for ballast replacement. The Keystone Ballast, core and coil, HID ballast kit is ideal for a wide variety of lighting applications, including factories, warehouses, gymnasiums and retail stores.
