After reading a few of his articles a few things pop into my mind: the data is collected through an inverted apparatus with just air and does seem to be corrected for the lack of water.... does that mean these tests are synonamous to having the LED fixture right on top of the water surface? That's what I would infer from these articles. I'm not sure many of us would mount a LED fixture right at water surface for fear of splashes, salt spray and heating up the tank for nano's.
I guess what I'm saying is take the numbers with a grain of salt and don't heavily rely on the PAR levels for picking coral (I was just about to do that because I'm still researching for the right fixture)! I think what the reader should take from these articles is the spread and (relative) intensity comparisons.
A good read and a good find! I'll have to look into these articles in greater detail when I'm not at work. If anyone does read these articles in great detail before me, let me know if the tester included any correction for hanging the fixtures 6-12" above the simulated bottom of tank/measuring point.
