175 Watt 10000K Metal Halide Bulb - XM, Mogul Base Information


The XM single-ended metal halide bulb offers good coloration and intensity. The crisp-white color will illuminate your tank nicely. It is very similar to an Ushio10,000K 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 electronic ballast. An excellent choice for nano-reefs and other reef tanks up to 18" 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 during installation and replacement.

* 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.

Comments: I bought this to replace an existing 10K MH bulb. This new bulb is quite a bit more yellow than the old Coralife bulb I replaced. Based on the coloring, I would probably try another brand or move to a 14K bulb.

Comments: Using an electronic ballast from Hamilton, I was able to get a nice, crisp white light from this lamp. The intensity is also very nice, as it yielded quite high levels of PAR, which was perfect for my seagrasses and corals. The only yellowing I've noticed is with extended age and/or yellowed water, the latter of which this lamp will make more evident than most others, due to the white hue. Bluer lamps mask this more, IME.

Comments: I ordered two of these bulbs just 3 months ago. The color of light was a grungy yellow. One of the two lights has already burnt out.

Comments: These bulbs seem great to me. I'm not one of those people who are consumed with the color the light gives off, only how my photosynthetic creatures respond with growth and so far, so good in that regard. I would definitely purchase and/or recommend these bulbs again. Thanks for the recommendation from customer service (Steve and Robert are great!!!)

Comments: Well the bulb takes about 10 days before it takes its true color. My corals have never grown so much. The bulb is has a yellowish tint with a slight hint of blue. I would reccomend to anyone who wants their corals to grow like crazy.
