I'm interested in how they compare against sunlight.

I did a few more reads though and the li-cor (which most people say is the gold standard for par metering) almost always read lower then the apogee when tested with LED's, so I'm curious if we're finding out that they're not as powerful as we thought they were?

I'm looking forward to getting a hold of one of these and using our clubs older meter now since all my led channels will be seperate. I can see the difference in measurement per channel

Possible! I'm all for more accuracy

Still waiting for the amplifier boards and parts to land. If your multimeter has a 10uV range you can just use that
