Overview
The Advance 71A7971-001D HPS ballast is a 70-watt magnetic HID ballast designed as a core and coil component for industrial and commercial HID lighting systems. This unit features quad-tap voltage inputs (120/208/240/277V) and operates with S62 ANSI-rated high pressure sodium lamps. The HX-HPF (high power factor) circuit maximizes energy efficiency and is compatible with pulse-start ignitor technology.
