Ok I took the time and measured my tanks par today, but before I post all my LED fixture (Evergrow) PAR readings I have a couple questions for you. First, what firmware version are you using? Mine is V2. Second, when measuring PAR did you make sure that the sensor is directly under the light or perpendicular to the light source. The reason for this is you will get slightly different reading when the sensor is not perpendicular to the light source. Seneye Sensor doesn't have cosine correction like other par meters that's why it is imperative that the sensor is perpendicular to the light source when measuring PAR.

So here's what my par levels are: Please note that my light fixture is more than 3 ft above the water level of my tank.

ALL BLUES @ 100%, distance from fixture: ~48"



FULL SPECTRUM (100% Blues; 40 Whites), Distance from fixture ~48"



FULL SPECTRUM (100% Blues; 100% Whites), Distance from fixture: 10"



I used to pay too much attention about PAR, I have burnt lots of SPS when I started as I was chasing the PAR readings based on the PAR guidelines on the internet not knowing the correlation between my water nutrients and PAR.
