Arcadia 250 watt 14000 Kelvin metal halide lamp with FC2 end fittings.
Metal halide is generally accepted as the best substitute for nature when it comes to aquarium lighting.
The exceptionally high light output when compared to other lamp types such as fluorescent tubes, makes them a very effective light source, particularly for the larger tank set-up.
When choosing a lamp for use over a marine aquarium, there are two factors that are important.
Firstly, the light output has to be beneficial to the health of the livestock. This is particularly important in tanks containing invertebrates such as corals (hard or soft), anemones, and Tridacna clams.
A suitable light is one which promotes photosynthesis by the microscopic algae (zooxanthellae) which live within the tissues of such invertebrates.
This relationship between the algae and its host animal is extremely important. If the algae do not flourish within the tissue, then the health of the host animal will suffer, and in many cases will ultimately lead to death if not corrected.
Combined with this, a lamp must provide an effect which is visually pleasing to the eye of the fish keeper.
We all want the creatures in our care to be as healthy as possible, but if we can achieve this without compromising the aesthetic appeal, so much the better..
The 14000K Arcadia metal halide lamp actively promotes photosynthesis within the tissues of those invertebrates which utilise symbiotic zooxanthellae, and so allowing healthy growth.
Visually, the appearance is very clear and crisp, with excellent colour rendition, resulting in a very natural looking picture within the confines of the aquarium.
