If I had 3 LEDs, one green, one royal blue, and one 420nm violet, and I was measuring a point where the 3 LEDs were outputting the same PAR (theoretically, not measured by the meter), could I then calculate the true PAR measured by the Apogee meter by doing this calculation?
(response from curve for green X 0.33 + response from curve for royal blue X 0.33 + response from curve for violet X 0.33) X (Measured PAR from all 3 LEDs)
Basically, to explain this equation, if all three LEDs had the same PAR, then in that area, the PAR should be three times that of one LED, right? Then, the meter would measure the PAR coming from these three lights differently, because of the response curve of the sensor. I'm trying to compensate for this different response by doing some math.
Or is this completely wrong?
