* Metal halide lamps are the most intense form of lighting in maintaining a successful marine, invertebrate, reef aquariums. They are extremely powerful and usually prove to be very successful.
* Replace bulbs every 8 to 12 months to maintain maximum efficiency
* The metal halide light has an excellent color rendering and a very high lumen output.
* An ultraviolet screen of filter will be needed to protect the species in the aquarium from ultraviolet light that is produced from metal halide lamps.
* A chiller can be used to offset any temperature gains
* Depending on the types of invertebrates, the depth of the aquarium and the spectrum of the lighting the amount of light needed will vary from minimum of 1.5 watts /gallon to maximum of 6 watts / gallon for reef tanks.
* For example, small polyp stony coral, such as Acropora need strong light that is provided by a high temperature (kelvin) metal halide light.
* Power cord with quick disconnection from ballast to hood (fixture)
* Independent ON / OFF control of ballast
* 15 feet long heavy duty lamp cord
* Included 150 watts, 14000K blue spectrum to eliminate the use of fluorescent blue actinic.
