Metal Halide Light 20000K
The Arcadia 20000K Double Ended Metal Halide Lamp, supplied by 123 Aquatics is Arcadia's new addition to the series. As light passes through seawater in the marine aquarium, much of the visual content is filtered out rapidly - with the light at the red end of the spectrum being the light that penetrates least, and the blue end penetrating the furthest. As a result of this the light on reefs in the natural environment changes rapidly as the water depth increases.
At the very surface, down to a depth of only a few feet, the light in the water has a bright blue-white appearance, as replicated by the 14,000K lamp. As depth increases, and the light is gradually lost - starting at the red end of the spectrum, the water takes on a deeper blue appearance. Photosynthetic invertebrates at this depth have evolved to rely purely on this blue light, and have lost the ability to photosynthesise using red light (as land plants do).
The '20,000K' lamp has been developed to replicate this environment in the slightly deeper water - providing the light levels that the organisms need, and also creating an attractive 'moonlight' effect in the aquarium.
