the above numbers are interesting. But it would be much more practical if the numbers were taken at various heights up to 30" above the sensor level. Then ploted to see what kind of spread those par numbers are creating.
What I find interesting though is that par numbers for Blues is higher than the PAr numbers for the whites? This fixture must have a lot more Blue LED's in it than white LED's. While that is good point remember PAR meters are generaly more sensative to red light than blue light. But corals love blue light more than red light.
Unfortunatly if you ran these same test also with three different brands of PAR meters you would probably get three different sets of numbers as well.
