Orphek Contracted to Design the PR25XP

Orphek was contracted by an unspecified government marine research institution to design a variation of the DIF100XP. The amount of LEDs covering a broad range of color spectrums makes me vary curious of its final intended use and what type of research it is being used for.

In a nut shell the PR25XP consist of the following:

4 white 15K
2 true UV begin at 380nm
1 red 660nm
5 blue
Peak WL:Lp=455.0nm

Some of the data I received suggest that the 4 white LEDs are actually 20K. The ratio is:

60% 20K white led
30% 380nm-420nm
10% red a 640nm

I was able to get a glimpse of a portion of the research. It is unclear to me exactly what its intent is and what it means. I’ll share it with you to make of it what you will.
