250W 10000K METAL HALIDE SINGLE ENDED BULB—XM

The XM single-ended metal halide bulb offers good coloration and excellent intensity. The crisp-white color will illuminate your tank nicely. It is very similar to an Ushio 10,000K bulb but slightly more yellow.  Actinic supplementation may be used to create a bluer look. This bulb will work with a standard magnetic ballast, magnetic pulse-start ballast or magnetic HQI ballast. An excellent choice for reef tanks 22"–30" deep.

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. Using soft gloves is a good idea to keep finger prints off bulb. This is during installation and replacement. The average life expectancy of this bulb is 12 months.

Excellent!
XM, still a great value by jabloomf1230
Experience Level: Expert
Posted on 10/24/2007
Comments: Excellent, with nice blue-white color. These bulbs last about 18 months of 8 hour days and then they either lose brightness or even an electronic ballast won't start them. Why pay more from a 250W/10000K bulb?
Yes, I would recommend this product to my friends.
