Description

The XM single-ended metal halide bulb offers good coloration and intensity. The color is between an 10,000K bulb and a 20,000K bulb: white with a distinct blue tint. This bulb will work with a standard magnetic ballast or an electronic ballast. An excellent choice for nano-reefs and other reef tanks 22"–30" deep.

15,000K Color Temperature
Excellent with or without actinic supplementation
Operate on a standard metal halide ballast or electronic ballast
Standard Mogul base

Common questions/problems concerning metal halide lamps:

Metal halide lamps of the same kind are different colors?
Metal halide lamps operate by passing an electric arc through an arc tube that excites particles in the arc tube. When the metal particles reach an excited state they emit energy in the form of visible light. It takes 100 hours of operation before the metal particles stabilize and become a consistent color. All metal halides require 100 hours of operation before color and light output stabilize. All metal halides inherently have a slight color variation between individual lamps.
The metal halide lamp fires and then either burns dull or the arc extinguishes?
Usually the ballast and lamp are not receiving enough power. Metal halides pull a high current. Usually the problem is either there is too great a load on the circuit or the extension cords are of a small wire size and can`t handle the power needed by the ballast. Use only heavy duty extension cords and try running a ballast
off a circuit from another part of the house.
Do I need a cover shield between the lamp and the aquarium?
Metal halide lamps produce a large amount of UV and also have a potential of exploding. The single ended metal halide lamps have an outer jacket which eliminates most of the UV. However, they have an inherent risk of exploding and UL requires metal halide lamps to be enclosed. On double ended lamps there is no UV shield. Double ended lamps must have a glass shield or major eye injuries including blindness may occur.
Can I operate a ballast and lamp together which are designed for different wattages?
Each wattage lamp and ballast are designed together for optimal performance and safety. If you over drive the lamp it may explode and shorten the life of the ballast and lamps. If you under drive the lamp it will also shorten the life of both components and also may explode. Do not mix different type wattages of lamps and ballasts.

NOTE: The bulb should be handled carefully during installation and replacement. The average life expectancy of this bulb is 12 months.

Excellent!

Great Color by ROB KEMP

Experience Level: Intermediate

Posted on 1/2/2008 from JACKSONVILLE, FL UNITED STATES

Comments: I've used 10k Metal Halides for years but wanted to try a bluer hue for my softies reef tank. All the warm earth tones now have a bluer tint. My finger corals and mushrooms now pop with blue. My tank looks more "under water" now! I'm waiting for replacement actinic PCs to supplement my lighting. They should make the contrast even more dramatic.
Yes, I would recommend this product to my friends.

Excellent!

Great bulbs. by MIKE PARENT

Comments: I have been using XM 15k bulbs for a couple years now. They don't promote growth as fast as the 10k bulbs but give much better color to the reef tank. I highly suggest them.
Yes, I would recommend this product to my friends.
