Osram NV400w-01 Mechanical ballast

The Osram NV400w-01 is a mechanical ballast manufactured by Osram, designed to control and start metal halide lamps rated at 400W. Built from metal, it offers structural durability and long-term reliability in professional lighting installations. Its primary function is to regulate the current flow to the light source, ensuring stable and safe operation throughout its service life.

This mechanical ballast is suited to a wide range of applications requiring high-intensity discharge sources, making it an ideal component for industrial, commercial and professional lighting systems. It operates at an input voltage of 220–240 V, fully compatible with European electrical standards, and supports a single 400W light source. The metal construction ensures durability even under continuous use, with a rated service life of up to 50,000 hours. As a technical component, it is not associated with specific residential environments, but represents an essential element for managing high-wattage discharge lamps with maximum reliability.
