Holophane EC-1035-A High Pressure Sodium Ballast

The Holophane EC-1035-A High Pressure Sodium Ballast is a magnetic ballast that regulates voltage and current for high pressure sodium lamps, delivering reliable illumination and extending lamp life in industrial, street, and outdoor lighting installations. It supports 50/60 Hz operation, is fixture-mounted, and uses a copper/steel magnetic core with internal thermal protection and a high power factor configuration; input voltage is application dependent. Compatible with Holophane and other HPS fixtures, it is commonly used for roadway lighting, industrial facilities, warehouses, parking lots, and outdoor security lighting where stable starting and current regulation are required. Available in new, used, and surplus inventory, common replacements include Advance HPS Magnetic Ballast, GE High Pressure Sodium Ballast, and Universal Lighting Technologies HPS Ballast.
