Metal Halide Lamps
- Aqualine Metal Halide Lamps : The aqualine 10000 metal halide lamp has a color temperature of 10,000º Kelvin and a high percentage of the light output is at the blue end of the spectrum.

The Coralvue bulbs have a great combination in color balance and color temperature.

No actinic supplementation needed.
- 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.
