2. Metal-halide lamp - Wikipedia

   en.wikipedia.org/wiki/Metal-halide_lamp

   Like other gas-discharge lamps such as the very-similar mercury-vapor lamps, metal-halide lamps produce light by ionizing a mixture of gases in an electric arc.In a metal-halide lamp, the compact arc tube contains a mixture of argon or xenon, mercury, and a variety of metal halides, such as sodium iodide and scandium iodide.

3. Ceramic metal-halide lamp - Wikipedia

   en.wikipedia.org/wiki/Ceramic_metal-halide_lamp

   A ceramic metal-halide lamp (CMH), also generically known as a ceramic discharge metal-halide (CDM) lamp, [1] is a type of metal-halide lamp that is 10–20% more efficient than the traditional quartz metal halide [2] and produces a superior color rendition (80-96 CRI). [3] Applications for these lamps include shop lighting, street lighting ...

4. High-intensity discharge lamp - Wikipedia

   However, mercury-vapor lamps are falling out of favor and being replaced by sodium-vapor and metal-halide lamps. Metal-halide and ceramic metal-halide lamps can be made to give off neutral white light useful for applications where normal color appearance is critical, such as TV and movie production, indoor or nighttime sports games, automotive ...

5. Hydrargyrum medium-arc iodide lamp - Wikipedia

   en.wikipedia.org/wiki/Hydrargyrum_medium-arc...

   Hydrargyrum medium-arc iodide (HMI) is the trademark name of Osram's brand of metal-halide gas discharge medium arc-length lamp, [1] made specifically for film and entertainment applications. Hydrargyrum comes from the Greek name for the element mercury. An 18kW HMI Bulb

6. Gas-discharge lamp - Wikipedia

   en.wikipedia.org/wiki/Gas-discharge_lamp

   Compared to other lamp types, relatively high arc power exists for the arc length. Examples of HID lamps include mercury-vapor lamps, metal halide lamps, ceramic discharge metal halide lamps, sodium vapor lamps and xenon arc lamps. HID lamps are typically used when high levels of light and energy efficiency are desired.

7. Grow light - Wikipedia

   en.wikipedia.org/wiki/Grow_light

   Ceramic metal halide (CMH) lamps are a relatively new type of HID lighting, and the technology is referred to by a few names when it comes to grow lights, including ceramic discharge metal halide (CDM), [26] ceramic arc metal halide. Ceramic metal halide lights are started with a pulse-starter, just like other "pulse-start" metal halides. [26]
