At AquaCave, we offer some of the best selection & best prices on metal halide lamps for you marine, reef, and freshwater aquarium.
There is no other practical lighting source for an aquarium that will provide as much light intensity as metal halide aquarium lighting. This is why metal halide lighting systems are popular among reef keepers where light intensity is crucial for the survival of reef organisms. The need for light intensity provided by metal halides is even more important in deeper tanks. Metal halide lighting is practical for aquariums deeper than 16" and become a necessity for aquariums deeper than 30".

- ReefLux Metal Halide Lamps by CoralVue : ReefLux is the first true 10000K full spectrum metal halide bulb to be offered to the aquarium market. Other manufacturers claim to offer a 10000K lamp but that is just a marketing number of their best attempt to offer a full spectrum 10000K lamp. This is why they have a yellow or orange appearance and need to have some kind of fluorescent actinic to balance it out. Generally the more yellow or orange a bulb the more PAR the bulb will produce. ReefLux offers you the highest PAR rating without having to flood your aquarium with high powered fluorescent blue bulbs.
The ReefLux 12000K has the performance of the 10000K but with a touch of blue added.
