So the results from TEKNIK's goniometer testing came back today and we're pretty happy with the results.
2.47 umol/j for a CRI94 board isn't too bad at all. The other board tested 2.46 umol/j at CRI95.
First thing I'd like to do is thank TEKNIK for donating their time and resources to this project. Having actual data instead of "guesstimates" is invaluable. This data will be used to create IES files for typical light footprints and will save a lot of time compared to physically PAR mapping each light.
One thing that did surprise us is that there was almost no difference in efficiency between the three-LED board (Nichia V3F1 2700K CRI90 + Optisolis 2700K CRI98 + Seoul Semiconductor Sunlike 6500K CRI95) and the two-LED board (no Sunlike). So the revised Sunlike UV white phosphor LEDs are running at similar efficiency to the Optisolis.
The CRI ratings were a little bit off from those tested with our hand-held spectrometer: the three-LED board came in at 94+ and the two-LED board at 95.
Board readings were taken at 1.5A (1/3 power), 2.5A, 3.5A and 4A. These boards will both go up to 4.5A.
Here are the three-LED board results:
