Product Overview
The Philips Advance IMH-70-D-LF is a 1-lamp 70W electronic metal halide ballast designed for compact fixture applications requiring reliable performance, dual-voltage flexibility, and improved protection features. Its Intellivolt input supports both 120V and 277V power systems, making it suitable for a wide range of commercial lighting installations.
This ballast operates (1) 70W M98/C143-M143 lamp and features a durable metal housing with side-exit leads for easier placement in tight fixture compartments. Built-in protection logic helps reduce stress on the lamp and ballast by removing power from failing lamps and preventing repeated end-of-life cycling.
With end-of-life detection, automatic shutdown, and a 4 kV maximum ignition pulse, this ballast is designed for controlled, code-compliant operation in metal halide systems where performance and safety are critical.
