250 Watt 14000K Metal Halide Bulb - AquaMaxx, Mogul Base Information


The AquaMaxx Mogul Based 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. 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.

Comments: If you do a little research the company lists it as 14k but is comparable to a radium 20k it's a 20k bulb for some reason I didn't get that far but they had to label it as 14 it's blue as radium side by side but less chance of failure plus starts on my magnetic ballast that's why I got it ;) google stuff people ;)

Comments: Well I tried the Aquamax bulbs about two years ago and like the Prodigal son I'm back. The colors are excellent just enough blue and enough white so it doesn't look like your looking at everything through a blue filter. I'm running my bulbs off of Icecap electronic ballasts and they fire the bulbs and give it just enough umph to make things look great. The price of these bulbs are excellent. I tried the Phoenix 14K 250 watt bulb and it was just too blue for me on my electronic ballasts. Now I understand if you run the Phoenix on an HQI ballast the color is perfect, but I can definately say it was not perfect with regular electronic ballasts. I like the Phoenix soo much that I'm also running them on my 40 gallon anemone tank and I can say the anemones love it.

Comments: The color is nice. We switched from two 20ks to the two 14ks, the bulbs are still a very nice blue which really makes the color on the coral pop, but the light seems brighter which is what we were aiming for. The bulbs are a nice even and matching color and work fine so far. We did have to return a 250watt double ended we ordered at the same time same company that burned out in two weeks. So far the mogul base bulbs are working perfect, though. So we are a 2 out of 3 positive on this brand. The color is wonderful, nice and bright and crisp, but lots of blue!

Comments: I bought these just after Christmas because of of their price. I had been using Ushio 10k's for years, but thought I'd try to save some money this time. I switched to these and I've had great amounts of coraline growth, but they have killed all of my SPS. These things just don't put out enough! They are not 14k's, these are 20-30k's. When they're on, they barely light up the tank more than just my VHO's. I'd never buy these again. If I want to save money, I'll either switch to LED for long term, or use good bulbs like XM/Ushio and keep my corals alive!

Comments: I like this bulb. It is too blue though to call a 14K. To me, it is a nice looking 20K bulb. It brings out the color well from the corals. I would recommend it as a good 20K bulb (better than XM 20K IMO) but not as a 14K.

Comments: Just received the bulbs. Ran them for 6 hours but I love the color so far. They are running next to a Phoenix 250w DE bulb and there is VERY little difference. Very crisp color leaning more toward blue than white. Perfect for me! These bulbs have replaced two Reeflux 20k bulbs. I did not like those bulbs at all. Way too yellow...these Aquamaxx are by far nicer. Time will tell how they will burn in and how my coral respond, but am very pleased so far!
