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. This is why we have developed our new 14,000 Kelvin lamp. The output 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.

The lamp is available in three sizes - 150W, 250W, and 400W - The latter being particularly for the deeper than average aquarium, or those containing species of stony corals with a very high light demand.
