Orphek is well known for its LED innovations.
It is logical that Orphek thinks ahead in its design group to hold the position as one of the best LED aquarium light producers.
In cooperation with the University of Giessen, an experiment conducted by Dr. Patrick Schubert shows how well LEDs with the correct spectrum excel over other older technology light sources.
Orphek has specially designed an Orphek Atlantic V3 + with a special spectrum for that experiment.
For that experiment,a unique spectrum has been created with reference to the Schöpke action spectrum for SPS coral.
Even infrared radiation has been thought of since the infrared rays in the uppermost layer of water causes molecules to vibrate which is beneficial to carpet anemones and other photosynthetic reef dwellers in shallow water.
PAR/PUR IS REQUIRED FOR BOTH MODULES ON THE BASIS OF THE LOW MEASUREMENT OF 10-20 CM.
So here we have two very good examples. These confirm the efficiency range of 45 to 60%.
Orphek has thus driven it to the limit with the custom variant to get the best possible results for PAR/PUR and spectrum.
Now let’s take a look at the Science behind Orphek,
What is noticeable here is the high cyan range and the various UV LEDs.
Also, there is no red LEDs; pink was installed.
However, our demonstration model does not have any infrared LEDs.
The Atlantik model used by the University of Giessen already has.
Dr. Patrick Schubert will conduct an investigation here and will
continue to have rapport with Orphek and our team.
Above my private reef aquarium the experimental Orphek has been working for several weeks now.
And I can see a positive increase in growth and color development.
Oddly enough, the cyanobacteria is disappeared.
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 μmol / 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.
