What Is a Metal Halide Lamp?

A metal halide lamp is a type of high-intensity discharge (HID) light that creates illumination by sending an electric current through a gas-filled arc tube containing mercury and metal halides. This process generates a bright white light with excellent colour rendering, making it ideal for large spaces that require strong and clear illumination.

These lamps are widely used in outdoor, commercial, and industrial environments, such as street lighting, warehouses, and sports stadiums. Due to their high light output and broad application range, metal halide lamps have been a reliable choice for decades, especially where powerful lighting is needed.
