    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.

    en.wikipedia.org/wiki/Ceramic_metal-halide_lamp

    Streetlamp with a ceramic metal halide bulb Ceramic metal halide bulb with G12 socket. 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).

  4. Mercury-vapor lamp - Wikipedia

    en.wikipedia.org/wiki/Mercury-vapor_lamp

    High-pressure mercury-vapor (and some specially-designed metal-halide) lamps find application in molecular spectroscopy due to providing useful broadband continuum ("noise") energy at millimeter and terahertz wavelengths, owing to the high electron temperature of the arc plasma; the main UV emission line of ionized mercury (254 nm) correlates ...

  7. Sodium-vapor lamp - Wikipedia

    en.wikipedia.org/wiki/Sodium-vapor_lamp

    When the lamp is first started, it emits a dim red/pink light to warm the sodium metal; within a few minutes as the sodium metal vaporizes, the emission becomes the common bright yellow. These lamps produce a virtually monochromatic light averaging a 589.3 nm wavelength (actually two dominant spectral lines very close together at 589.0 and 589. ...

    Finely powdered magnesium metal alloyed with a small amount of iron, and table salt, actuated by adding water, as in an MRE flameless ration heater. Some newer formulations use a Thermite -like reaction between a more reactive metal powder such as aluminum or magnesium, with a less reactive metal oxide such as iron oxide or silicon dioxide [ 3 ]
