As promised, there is the upgrade to the V4 prototype at the University of Giessen. The following mail was sent to us.
We have been using the Orphek Atlantic V4 (prototype) for about three months to test in our seawater plant at the Justus Liebig University of Giessen. Changed from (over-aged) T5 tubes to LED. Although the lamp is actually too small for the selected basin, it impresses in the first impression despite the high distance to the water surface. At a height of about 60 cm above the water surface, an area of ??90 cm x 60 cm with a very good to good (120 cm x 75 cm) power is evenly illuminated. All stone corals showed a clear increase in growth rate and color after just a few days, with a water level of 60 cm being bridged well. A preliminary measurement yielded about 500 ?mol / m²s of PAR at a distance of 45 cm and a full spectrum, including the UV range, which can be individually adjusted and controlled via 4 channels. Allows a changing spectral composition during the day. We are very optimistic about a long-term test of this lamp.
