250 Watt 6500K Metal Halide Bulb - Iwasaki, Mogul Base Information




250W 6500K MH BULB—IWASAKI

The Iwasaki 6500K metal halide bulb is a full-spectrum Daylight bulb. It offers excellent light intensity, but will be slight yellow-green in coloration. A great bulb to achieve fast growth. This bulb will work with a standard magnetic ballast, magnetic EYE ballast or electronic ballast.

This 250W bulb is great for reef tanks 22"–30" deep. on how the different Kelvin ratings appear and more information on metal halide bulbs.

As a general rule of thumb, use one metal halide bulb for 24" of tank length. Most of the Metal Halide bulbs in the same wattage format can be interchanged. However, please contact us to make sure. Metal Halide bulbs are one the most difficult aspects of the hobby to recommend. Most of the information here is general.

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.

Great for growth but yellowish

Comments: Great bulb for coral growth. In fact, it is one of the best that I have used. The downside - its appearance in the tank looks yellowish. It is a good bulb to use with supplimental actinics such as T12 VHOs or T5s - that will help give you less yellowish look. Overall, it is a great product.

Comments: Using two of these with 2 pairs 420nm (actinic 03) and 460nm (blue) PC bulbs over my 150g display tank. Definitely needs the supplementation, but the outstanding PAR values and long life of the lamp are fantastic.

Comments: Found 1/2 bulb submerged in water and no fracture. My clams without question have greatest growth with the 6.5K I've tried many, and have returned to the Iwasaki. Only wish it came in DE.

"As always my experience with Marine Depot was 'overall satisfaction.' If on the phone, by video or the write-in reviews on the product I am interested in, they are always helpful. When I am in doubt of what product will help me or where to find it, Marine Depot is usually the first and last place I go to."
