Already at few meters of depth of water, the red component of natural light is filtered out. This circumstance is often borne during light of sea water systems with fast ones for ""NDL"" or for ""D"" torches through it bill that neon tubes in blue coloring (e.g. Philips TL03) connected however, combined with high vigour expenditure at comparably small light power (a HQI-TS 250 shallows "D" has on a luminous flux of 19000 lumens, a HRI torch 400 shallows "D" a luminous flux of 45.000 lumens!).

The KORALLIN navy blue light system works with a special lamp, its radiation maximum in the case of 450 nm wavelength is. Consequently, the effort of additional blue lights expensive in the purchase and the support is unnecessary since this torch over 20.000 kelvin achieved and therefore a marvellous light color without besides necessary influencing offer.

Long-term test proved that this is an optimal radiation source for bigger sea water tanks.

On account of the high luminous efficiency admit itself to illuminate a 2 m tank with 2 blue optimal (reflector measure 260 times 260 mm!). Depending on animal trim, one can choose between 250 and 400 Watt.

The employed T-lamp with screw cap is produced of hard glass, which light not passing wavelength (noxious ULTRAVIOLET B and ULTRAVIOLET C) among 350nm omit, the vital ULTRAVIOLET A radiation can instead pass without obstruction.

The reflector case is from aluminum die casting and consequently offers optimal long-term protection against corrosion.

It exists choice between the purpose oriented, economical built-in version "economic" with integrated input unit and wall mounting mechanism (as extra with smooth height adjustment) or the exclusive Marine blue "designer collection" with pretentious lining in genuine wood and / or marble according to individual wish with external input unit.

Measures in mm approx. (identically 400/250 shallows):

Economic:                       Depth 300, width 400, height 300

Color: Economic:             Case black

Emphasis:                        Economic: including torches, approx. 10 kg
