XM Lighting

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 up to 3` 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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.

Bulb Replacement Guide
Bulb Types Life of Bulb*
Normal Output Fluorescent 6-12 months
Very High Output (VHO) 6-12 months
Power Compact (PC) 9-12 months
T5 High Output (T5HO) 9-18 months
Metal Halide 9-12 months
LED (non-moonlight) ~5 years (50,000 hours)
* Manufacturer Recommendations
 

**Please Note** Pulse start type lamps may ignite and work just fine on a probe start ballast for a few months; however, as the lamp ages, the electrodes erode and higher voltage is needed to start the lamp. The open circuit voltage provided by probe start ballasts is not sufficient to ignite a pulse start lamp.

Not Blue Enough

The brightness is there, the blue isn't. For being a 15,000K bulb, this thing is very bright white. If you're looking for blue, go with the 20,000K bulb.

XM 15k

I have used many different types of bulbs but I prefer the crisp blue/white color from the XM bulbs. I have been using XM for about 4 years now

Great color

I am very pleased with these bulbs. My corals are already reacting to the new lights. If you just want to run these bulbs alone, they have a great blue tint to them that is just enough to bing out the colors of your corals and fish! not too much, Just enough! I will buy these again. Thanks for a great product. Good fast shipping and very good packaging. No problems.

Love These

I've been using XM bulbs for years and have never been let down. Corals love them and they have always been consistent in color and intensity. I run 2 250 watt IceCap digital ballasts and these fire up quickly.

They Work

Great price for something that works. Excellent color ...not to bright (white) and not to dark (blue). Easy on the corals and eyes. Most of the corals respond well the the change for 10K blubs.
