60 – 18Kwhite
10 – 450nm blue
10 – 430nm actinic
10 – 410nm UV
6 – 590nm orange
4 – 660nm red
If you look at Cree XP-G LEDs on their web site, the white diodes are only available in cool white or warm white so much more blue must be added to achieve the desired color.
For example, the Orphek aquarium led lighting DIF 100XP which does not use Cree LEDs, but uses our own proprietary 18K white diodes. Orphek LED Emitter have no model numbers; you cannot order these LEDs from a LED company for DIY projects.
Orphek uses several American LED companies to produce their diodes to their exact specifications.
We have never used cheap Chinese made diodes in any of our products.
With Orphek’s revolutionary technology we have designed the first white 18K LED that actually produces blue with no appreciable loss of lumens per watt.
The benefits of this new diode technology are high lumens per watt as well as a high CRI index.
There is not another aquarium LED lighting manufacturer that can state this. Our fixtures are very low in the 550
0nm range which is the range nuisance algae and cyanobacteria thrive on.
In the graphic below you can see the high amount of light being generated by the Cree 7000K LED in the 550
0 wavelengths. Compared to Orphek’s white LED emitter, this is very high and will contribute to nuisance algae and/or cyanobacteria.

Rob sicuramente la strada battuta è meglio di quella nuova, ma sicuramente la nuova porterà a grandi cose. Come saggiamente hai detto tu, bisogna imboccarla ed accettarne conseguenze positive e negative.
