Challenges in aquarium lighting The complexity of a perfect formula In recent years, more and more public aquariums have shifted from being biological collections to providers of underwater world experiences for visitors. The fascination of an underwater world is strongly enhanced by the mystic atmosphere of an aquarium. A good aquarium allows the spectator to submerge into the scenery. To create the right atmosphere, most curators resort either to deep blue or reef green light conditions. Blue enhances the sense of depth. It allows schools of fish to appear seemingly out of nowhere and...

Natural settings and human requirements in balance We listen to our clients and advise them on the best possible lighting solutions. Our R&D department and laboratory in Germany as well as our scientific and photobiology specialists work closely together. This allows us to offer a wide range of lighting options that combine the different requirements of aquarium lighting in the best possible way. To really fit your needs. ENVIRONMENT • Diurnal cycle • Natural habitat CORAL • Photosynthesis • Fluorescence

High-performance LED luminaire for deep ocean aquariums Blue and white LEDs with optimal performance, luminous efficacy and service life have been combined to bring the best in aquatic illumination. The projector can have two separate adjustable controls for white and blue, allowing the light colour to be varied between 6 700 K and 20 000 K+. This gives the aquariums a wide range of options for adjusting the light to meet specific needs or create special effects. Chromaticity diagram 6 700 - 20 000 K+ • High-performance LEDs providing 31 000 lm @ 6 700 K • Optimised cooling with heat pipe...

Deep blue ocean scenery Submerging into the mystery of the depths “We have been using the NEPTURION 500 W LED projector with 25° for several months now in our 650,000 litres tank featuring Reunion Island habitats. The penetration of the light in this 6 m deep tank is very effective, as if sunbeams were shining into the aquarium.“ Guillaume Eveillard, Curator at CINÉAQUA Aquarium de Paris, Franc

Powerful LED luminaire for mid-size aquariums The combination of special blue, cool white and warm white LEDs guarantees an outstanding performance, luminous efficacy and service life. It comes in three versions and you can choose between three beam angles (100°, 55° and 35°). • High-performance LEDs providing 18 000 lm @ 5 600 K • Tool-free assembly and disassembly above the water • Driver module separated from water area • Only 6 kg above the water thanks to separated driver module • Choose between three different versions and three different beam angles for a perfect light distribution:...

Vivid and dynamic underwater scenery Getting as close as possible to a fascinating world “Our solution with NEPTURION LED 250 W 55° and 100° gives fantastic illumination to the fish tanks, and we have seen very good growth in the tanks after installation. We are really satisfied with the investment.” Geir Olav Melingen, CEO at Akvariet i Bergen, Norwa

Powerful LED luminaire for smaller and mid-size aquariums This LED luminaire is the optimal choice for aquariums and tanks up to 4 metres deep. The combination of special blue, cool white and warm white LEDs guarantees an outstanding performance, luminous efficacy and service life. Like the other NEPTURION LED modules, it comes in three different versions and you can choose between three beam angles (100°, 55° and 35°). Chromaticity diagram 5 600 - 20 000 K+ • High-performance LEDs providing 7 200 lm @ 5 600 K • Tool-free assembly and disassembly above the water • Optimised cooling with...

Shallow water scenery Discovering the unlimited variety of colours “After a successful test installation, we decided to buy NEPTURION 100 W LED projectors with 55° and 100° beam angles. We are using them for our 60 000-litre tank featuring the Amazon River environment. With the NEPTURION LED luminaires we are able to perfectly reproduce the freshwater environment of this region.” Marek Bytnar, Curator at Palmiarnia Miejska, Pola

Important aspects of lighting in a coral reef tank Coral reefs are one of the great wonders of marine life. Their lively and colourful inhabitants constitute a fundamental contrast to the slow, majestic movements of large fish in the deep blue ocean. It is, therefore, a centrepiece of many aquariums. However, reconstructing a healthy coral reef in a tank is a technical and biological challenge. The diversity of species that meet at the reef requires a well-balanced tuning of nutrients, temperature and light conditions. Coral reef lighting always involves a compromise of the requirements of...

LIGHT INTENSITY The first and foremost aspect of lighting is its intensity, defining how "bright" the light is. For biological applications, light intensity is usually given in photosynthetic photon flux density (PPFD). The unit is pmol m-2 s-1. Alternatively, the term photosynthetically active radiation (PAR in Wm-2) is used. LIGHT QUALITY The spectrum defines whether lighting promotes photosynthesis and/or provides good visibility. Therefore, photobiologists refer to the spectrum as light quality. Light intensity and quality are crucial for photosynthesis and consequently also for coral...

LED luminaire especially for healthy coral growth A unique combination of LEDs has been assembled for a perfect spectrum for corals, matching the photosynthesis curve of the zooxanthellae. It promotes photosynthesis – which is crucial for coral growth – while simultaneously providing a stunning experience for visitors. • High-performance LED selection especially for coral breeding and for supplemental assimilation light for corals in larger display tanks • Same colour temperature as the familiar NEPTURION MH 20 000 K+ series • Optimised cooling with patented passive cooling technology on...
