Seneye Data

jharding08 · 04/18/2016, 11:38 AM

So I bought a Seneye for the PAR meter, mostly. I have dimmable LEDs that have three channels - cool white, royal blue and a mixed that has Violet UV, Green and Red.

I noticed that the Seneye measures Kelvin, but when I put it under my LEDs, it says Not Kelvin. I was hoping to tune the channels to reach 20K using the Seneye.

Is K levels that important or as long as PAR is in an acceptable range, then I could just experiment with the intensity combinations?

Is there more information in the dashboard graphs that I can use to determine if my lights are where I want them?

PAR is almost the only thing that matters.

Frequently color in degrees kelvin doesn't match a color you'll find. degrees kelvin is a specific range of color, and sometimes even our hobbyist lights reach a color that isn't on that very standardized scale. It's actually kind of neat how they calculate degrees kelvin (and why it is called a temperature measurement instead of a color/spectrum measurement).

Find a PAR you want, tweak colors to taste, not too much red.

For a mixed tank, does 100-300 with a high of 450 sound right? Since i dim my own channels, if I get the right par, but wrong color, then if I change a color, I will have to repar everything right?

That range sounds pretty good for a mixed tank. Some SPS tanks can be acclimated to higher levels, but I wouldn't start there.

Most of your PAR should be in the 400-500nm range. 450nm is the common peak due to the lighting sources we use.
