Metal Halide Aquarium Lighting
Metal halide aquarium lighting is the lighting of choice for many reef aquarists. Metal halides produce more lumens per watt than any other aquarium lighting source.

Four 250W DE metal halide lamps available within the reef hobby were evaluated along with the ballasts used to drive these lamps.

Metal Halide Light Bulb
Metal Halide lamps typically range from 175-1000 watts and have Kelvin ratings from 5,000° to 20,000°.

Metal Halide Lighting: Metal halide lights are a type of light bulb that emits very white and very bright light. They require a special fixture and ballast.

Metal halide - Lamps that produce very hot and very bright light. Used as an artificial sun for reef tanks.
Nitrification - The process where ammonia is converted to Nitrite (NO2) and eventually to Nitrate (NO3).

Metal Halide Lighting: Metal halide is considered by many to be a best method of lighting reef tanks. They burn much hotter than incandescent, high output (HO) and very high output (VHO) lighting.

metal halide - A very intense type of lighting used in marine and freshwater plant aquaria.

Metal Halide & Mercury Vapor technologies are not for the mainstream marine aquarist. Though some types of metal halides produce good quantities of the desirable qualities of light at a low enough cost, they also many drawbacks.

Metal Halide: A type of light bulb that uses special gases to give off a very bright white light. They give off a spectrum of light very similar to sunlight and are highly recommended for reef aquariums.

Metal Halide Lights - Very brilliant and broad-spectrum lights used in some Planted Tanks for growing plant species that demand high-intensity light to thrive, and in saltwater Reef Aquariums.
Milt - Fish semen.

[edit] Metal Halide
Metal halide lighting is quite popular in the hobby, and for good reason. It is cost effective, dense, intense and somewhat efficient.

Metal halide lighting is recommended for aquarists planning to keep SPS corals and clams, or if you have a tank deeper than 24 inches. Like the sun, metal halide bulbs have one point of light, so it creates a stunning shimmering effect.

Metal halide lighting form the last part of the light section. These are very intense, very expensive lights suited to only very heavily planted tanks and saltwater tanks with invertebrates. They produce a lot of heat, so are usually fan cooled.

Metal Halide fixtures are designed to either hang above the fish tank or be mounted in special tops, in order to disperse the light and the amount of heat radiated to the aquarium.

Metal Halide lights should not be placed closer than 30 cm to the water surface, or they will overheat the tank.

ballast The electrical supply for some lights, such as fluorescents and metal halide bulbs. These are available in several varieties, such as tar, transformer, and electronic. They must be properly matched to the type of bulb you are using.

I suggest between 2 to 3 watts per gallon of tank capacity of either fluorescent or metal halide lighting. Good lighting and plenty of plants are important to the success of an soil substrate.

Metal Halide (MH) lights are most commonly seen illuminating football fields, but are also used in our hobby by reefkeepers and die-hard plant enthusiasts, who demand very high light intensity.

Often regarded as the best of the best lighting can have, Metal Halide is most expensive of the lighting technologies. This is so as the Metal halide (MH) bulbs require special, highly complex ballast to fire them.

Another lighting option for aquariums are metal halide lights, or M.H. lighting. Metal halide lighting requires special ballasts and special fixtures, and the lights use a lot of energy and produce a lot of heat.

For example, if you want to keep mushroom polyps, which prefer more subdued fluorescent lighting, you wouldn’t want to subject them to the merciless glare of high-wattage metal halide lamps.

Power compact (PC) fluorescents, T5 fluorescents, and metal halides (MH) dominate the planted tank hobby.

Any type of fluorescent lamp or metal halide lamp must be plugged into a ballast before a power source, because gases in the bulbs are unstable and they can actually explode without a ballast to ground them.

Then the various power ratings available from a meager 9 W fluorescent lamp to a blinding 1000 W metal halide.

Because this Leather Coral comes from greater depths where it is not used to intense illumination, when introducing this species to your tank, you will need to gradually acclimate it to metal halide lighting and ensure that the type you use provides ...

You need to provide massive amounts of light through metal halide lighting in a daylight colour temperature (what colour the light is) and actinic light to provide the blue wavelengths from fluorescent tubes or power compacts.

For instance, a 400W MH (metal halide) bulb puts out about the same intensity as 10 X 40W FL tubes.
However, because MH light is a point-source light, ALL the intensity is concentrated at one point ...

Metal Halide lighting being the ultimate, yet most expensive option, Power Compacts seem to be a popular choice for planted aquaria. Bulbs are expensive, though, and fixtures aren't within the reach of every hobbyist, either.

Keep in sunny window or under very strong fluorescent or metal halide lighting. Water thoroughly throughout the winter, or keep in kiddy pool or other indoor "pond".

Depending on if you want to keep what types of corals, you can go with regular light bulbs or go as complex as metal halides for harder to keep anemones for hosting your clown fish.
