The 400 Watt HPS Ballast Wiring Diagram outlines the entire electrical system for a high-pressure sodium lighting system. It includes a detailed schematic representation of the cables and colors used in the wiring, as well as the connection points where they join.. Here we display wiring diagrams for High-Pressure Sodium Ballast, metal halide (pulse start) and high pressure sodium HID ballast kits. Assemble the necessary materials for your High-Pressure Sodium Ballast if you are constructing your lamp without a kit.
A complete wiring guide for High Pressure Sodium (HPS) lamps—learn components, diagrams, safety tips, and installation best practices.. Sodium Vapour Lamp - Construction, Working and Wiring Diagram: Principally the sodium vapour discharge lamp consists of a bulb containing a small amount of metallic sodium, neon gas, and two sets of electrodes connected to a pin type base. The presence of neon gas serves to start the discharge and to develop enough heat to vaporize the sodium. Since long discharge paths are necessary.
