One of the things I do not like about my ufo 90 is that the diodes are too close together, which minimizes useable footprint on canopy.
Another problem is that it is only B/R diodes.
I would go with clusters of leds where distance from each diode has been taken into consideration, as well as diode spectrum balance, which R/B only fails to address.
