Lighting for coral reef aquariums
is much more complicated than lighting for a house. Corals have needs that are heavily dependent on light. Hard corals, in particular, generate their exoskeletons with photosynthesis. Without intense light, they will not be able to form their exoskeletons properly.
This is the reason why lighting is a very important factor to consider when you own coral reef aquariums. You can't just walk in a hardware store and grab a couple of lamps. Luckily, the 150-Watt 14000K Metal Halide Bulb - Aquamaxx, Double Ended from Pet Store
is made to solve that problem.
This bulb gives off a very crisp and clean white light with a slightly bluish tint. This combination of white and blue works perfectly together to nicely bring out the vibrant pigments of the corals. The result is a stunning display that no other lamp can deliver. This bulb also has a high-intensity light that doesn't need supplementation - unless you want to add more to improve the simulation of nighttime and daytime.
The 150-Watt 14000K Metal Halide Bulb - Aquamaxx also is perfect for tanks that are at least two feet deep. The light it gives off is intense enough to reach deep areas within such tanks.
150W 14000K METAL HALIDE DOUBLE ENDED BULBAQUAMAXX
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:
- 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.
- 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.
- 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.
- 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: These bulbs have really brought the color in my aquarium on my corals to life, they have a slight blue tone to them, so just know that but you won't be dissappointed.

Comments: I purchased this product when I recently was unable to find my regular MH bulbs in stock at most online retailers. I will use this brand from now on. Great color spectrum true to a 14k MH lamp, great price. Totally worth it. Tank looks awesome!
