Parmar 70w SON Ballast

This Parmar 70 W SON Ballast is specifically designed for application with 70 W SON (High Pressure Sodium) lamps, making it a straightforward replacement unit for existing SON I installations. It operates on a 230‑240 V mains supply, and is constructed as a magnetic ballast with robust build and proven performance in industrial and commercial lighting systems. The ballast supports the correct starting and running conditions for the tube, offering compatibility and reliability for your installation. 

In terms of specification, the unit aligns with the typical Parmar control‑gear range, offering a compact footprint and compatible mounting dimensions as listed under the Brompton catalogue for magnetic ballasts from 35 W to 400 W. Installation should follow the wiring and capacitor requirements: when used with other discharge lamps such as metal halide, an ignitor and correct capacitor must be provided. For SON I lamps however, only the correct capacitor is required.
