Metal halide bulbs come in a variety of spectra from 5000k on up to 20,000k and allow for a variety of light-hungry corals to survive under them. Many aquarists will use metal halide bulbs in conjunction with either power compact fluorescents or T5 fluorescents since halide lighting does not have the overall balanced effect of other light types.
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.

Metal halides are available in many color temperatures, from 6500 K up to 20,000 K, though bulbs as high as 50,000 K are occasionally found. The downsides of metal halide lighting are the initial cost and the heat produced. Most metal halide fixtures are more expensive than fluorescent systems, but are required for some reef setups.
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 headlamps, and aquarium lighting.
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).
Full spectrum lighting also enhances the natural coloration of fish, plants and other aquatic elements in an aquarium, which are often discolored by artificial lights. Full spectrum lighting is typically used more in fresh-water aquariums since marine or coral-reef aquariums often require intensely blue light.
The halogens can all react with metals to form metal halides according to the following equation: 2M + nX 2 → 2MX n. where M is the metal, X is the halogen, and MX n is the metal halide. Sample of silver chloride. In practice, this type of reaction may be very exothermic, hence impractical as a preparative technique.
Theater metal-halide lamps use G12. In addition to being used on light bulbs themselves, the G38 connectors are also found as a part of the Raylite reflector assembly, although some Raylite reflectors have "tails" which then require connection to the mains flex with the use of a ceramic connector block (ideally fixed to the can's body).
