How Ceramic Metal Halide Lighting Works

CMH lighting operates on the principles of high-intensity discharge (HID) lighting, with some key differences:

1. Ceramic Arc Tube

The ceramic arc tube is the heart of a CMH lamp. Made from polycrystalline alumina (PCA), it can withstand higher temperatures and pressures than quartz arc tubes, resulting in better performance and longevity.

2. Metal Halide Mixture

The arc tube contains a mixture of metal halides, which vaporize when heated, producing a broad spectrum of light.

3. Electrical Discharge

An electrical current passes through the gas and metal halide mixture, creating an arc that produces light.

4. Ballast

A ballast regulates the electrical current to ensure stable operation and prevent flickering.
