Wonder if anyone has tried the Seneye for PUR measurements.
Just looked at your build thread and it looks like you're running a Kessil 360 on your tank. Awesome light, but a PAR meter won't do you much good. Measuring PAR on an LED light isn't particularly accurate, but on a Kessil a PAR meter doesn't work at all. On Kessil's website they indicate the only way to properly measure is with a PUR meter which almost no one has.

The issue that the sensor is not as sensitive in all wavelengths. So it will measure some wavelengths better than others.

San Francisco@Schmitty is a member and I currently have the par meter, where are you located?

Doesn’t really matter to me, the corals tell me what I need to know.

Those correction factors are over simplified for the end users.
Even with a $3k Licor system, the numbers are off.

Do you have the apex sensor?I keep track of my PAR on the tanks with T5s simply to watch how much they degrade over time. Plus having the PAR reading constantly displayed on my apex screen is just cool.
I really think Kessil is over simplifying the issue for marketing purposes.
The PAR on Kessils can be measured fairly well. From all I can find, probably within 15% using the clubs PAR meter.
Light is light. Although as the spectrum diverges from "normal", error is introduced in sensor.
So not perfect, but hardly completely wrong.
BUT: The real point is that simple PAR numbers are imperfect for comparing different LED lights in reef tanks.
You technically want to just measure the exact spectra that Coral want.
Some argue that is PUR, others argue it is even more complex.
PAR may work for comparing different lights that all have roughly normal spectra.
But if some have very different spectra, like Kessil, it is hard to compare.
So instead of saying all that, Kessil simply says you cannot measure it.
