150 Watt 15000K Metal Halide Bulb - XM, Double-Ended

MB2763

This item has been discontinued.

XM Lighting The XM 150W double-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 standard magnetic ballast, magnetic pulse-start ballast, magnetic HQI ballast or elextronic IceCap ballasts. An excellent choice for nano-reefs and other reef tanks up to 22" deep.
  • 15,000K Color Temperature
  • Excellent with or without actinic supplementation
  • Operate on a HQI metal halide ballast or electronic ballast
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.

good bulb

REVIEW
This bulb is a bit more blue than one would expect for a 15K. That being said the intensity is bright enough to make up it. I've tried the XM 10k's and the Phoenix 14K's and I like the XM15k the most. The bulbs will need to be replaced at least every 12 months. Noticed significant loss of color ...Read More

This is the closet your gonna get to Radium's. I have used Phoenix and I will never use any other again. For a Sps dominant tank I love the blue color and the par is right on with the mogual base 250w Radiums

REVIEW
I purchased the XM 15K bulb predominantly based on reviews and I couldn't be more disappointed. This was to replace a 14K Phoenix that has been performing flawlessly for 12 months. The XM bulb would not fire after multiple attempts even with a dedicated circuit. After 23 attempts I got the bulb ...Read More

Nice Color Temperature

REVIEW
I have only been running the bulbs for about a week. I switched from Ushio 20K's. Only problem is that the bulb appears to be significantly more intense than the Ushio (may just be color temperature) and as a result, I have had to shorten my light period since some corals were showing burnt tips. ...Read More

Excellent Bulb for 8 Months

reviewerbadge
REVIEW
I have been using this XM bulb for 3 years now (changed the bulb every 8 months during mentioned 3 years), and am very satisfied with the stability of the light and it's reliable firing when used with reef timers. For a 15K bulb, they are a bit more blue than one would expect but I enjoy that look. ...Read More
