400W 14000K METAL HALIDE SINGLE ENDED BULB—HAMILTON

The Hamilton single-ended 14000K 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 ballst, magnetic HQI ballast and electronic ballast. An excellent choice for  reef tanks 24" or deeper. 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.

Bulb Replacement Guide
Bulb Types Life of Bulb*
Normal Output Fluorescent 6-12 months
Very High Output (VHO) 6-12 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.

This bulb is quality color

Hamilton has been producing these bulbs for over a decade and it shows. The color is white just a tint of blue, and my old IceCap Electronic ballasts drive it perfectly. As an alternative I do recommend the Aqua Max 14K bulbs also, maybe a tad bit bluer, but very nice coloration. For a standard electronic ballast i cannot reccomend the Phoenix 14K bulbs just too blue closer to 20K if you ask me. Now If you overdrive the Phoenix I'm sure the color is nice, but a standard Electronic ballast its a no go, at least for me.

Great bulb

Color looks great, I like it better than the Phoenix bulb that I previously had. This one seems whiter and more crisp.

EXCELLENT COLOR

My favorite halide bulb on the market. A really nice mix of blue and white color in this bulb. Brings out a fluorescence from the corals in my tank.
