Lighting System
The Dupla Lighting System exclusively comprises lighting equipment that reproduce the natural light in fish' and plants' natural biotope both in fresh water and in sea water in an excellent way. They thus fulfill the two important functions of light:
- to put the underwater world in the right light setting and
- to supply the necessary energy for plant growth.
Criteria for aquarium lighting:
- Light's most important function is to provide the aquarium plants with sufficient energy for optimum metabolism; amongst other things the assimilation of nutrients incl. CO2 and the discharge of oxygen to the water.
- The light day under water is shorter in tropical waters than the light day above water. This is a consequence of the angle of refraction in the water. The sunrays do not penetrate the water until they are at a certain height above the horizon. Thus the light day under water amounts to approx. 8 to 10 hours. The consequence for the aquarium: strong light but a shorter period of illumination. Even 14 hours do not bring about 100% oxygen saturation!
- Many plants which are used in the aquarium as foreground plants, e.g. Echinodorus tenellus, lilaeposis nova-zelandiae, etc., grow on embankments and receive the most light there. If the lighting is weak though, they will obtain too little light in the aquarium, assimilate only inadequately and rot.
At the occasion of the companies 20th anniversary, Dupla has developed a complete new lighting range of lamps made of aluminium which we introduce for the first time in this homepage. A new design and material as well as more lights are significant for the Duplaelectra. The Duplaelectra meets the individual requirements and offers an optimal light for freshwater – and seawater aquariums.
