10000K Metal Halide Bulb - Hamilton, Double Ended Information




The double-ended 10000K metal halide bulb offers excellent coloration and good intensity. It is crisp-white. It brings out the fluorescent pigments in corals nicely. Fluorescent supplementation is usually not necessary, but can be used for added intensity and to simulate dawn and dusk. An electronic ballast, magnetic pulse-start ballast or magnetic HQI ballast is required to ignite this bulb. It must also be housed inside a pendant. It cannot be used with simply a reflector in an open application as UV rays emitted by the bulb must first be filtered with a UV-proof lens. An excellent choice for reef tanks 22"–30" deep.

The Hamilton single-ended 10000K metal halide bulb offers excellent coloration and good intensity. It is crisp-white with a blue tint. It brings out the fluorescent pigments in corals nicely. Fluorescent supplementation is usually not necessary, but can be used for added intensity and to simulate dawn and dusk. This bulb will work with a standard magnetic ballast, magnetic pulse-start ballast or electronic ballast. An excellent choice for reef tanks up to 18" deep. on how the different Kelvin ratings appear and more information on metal halide bulbs.

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.

Comments: This 250w burns like a 15K. It definitely burns white as apposed to blue. Since buying this bulb a week ago, I purchased a Coral Color 20k which outs out a nice blue-ish hue.

Comments: I really like the look of this bulb. I have it over my reef tank and I get good coral growth - SPS has been doing great with this bulb - and nice color. It works best with actinics - right now I am using it in conjunction with 2 - T12 Super Actinic blue bulbs. It is a great combination if you want color and growth.

Comments: One of the main benefits that made me choose this bulb is its ability to penetrate aquariums deeper than 33 inches, like mine I have not put the bulbs work but I'm sure I made a good choice no more

Comments: I put this in the day it came in. So far a like the blue tint of this light. It came well packed, which is maybe something people forget about, but it's important when it comes to this kind of product. I can't really say much about how much my corals like it as of yet.

Comments: I used this bulb to replace an AquaMaxx that burned out on me in a matter of weeks. The Hamilton is a nice blue, but not quite as bright as the AquaMaxx. It certainly is lasting much longer, though! It is more blue than white; it appears closer to a 20,000K than a 10,000k. The colors of the coral are really brought out by this light, especially the greens and purples, but I was hoping for a light more as advertised "crisp white with a blue tint". The coral looks good and grows well under it which is what counts, though.

250 Watt 14000K HQI

Experience Level: Intermediate


Comments: I am not really impressed with this bulb due to the weak ceramic base on the sides. I inserted it into my reflector and without to much preasure the top portion of one side broke off. Not that this reflects on the bulb performance, it works great. It could be beefed up a little on the sides. Overall the 14000k color is stunning and the bulb really does work great. Just be careful not to press to hard.
