Sorry for the wait and thanks for your patience. I just finished putting the Nichia 083 into another Q3 host and had the opportunity to compare the 083 running at 333 mA side by side with the 183 running at 800 mA. The difference is just not great enough to warrant the effort of taking another set of beam shots IMO.
The tints are quite close to one another and they render colors equally well. The only difference is the increased brightness of the 183, but given the much greater drive current the difference is not impressive. Part of the reason for this is certainly due to the floody nature of the beam, which does not produce much of a hotspot. If there were more of a concentrated hotspot, then I would expect to notice a greater difference in throw especially.
Overall, I still like the high CRI LEDs, but the sheer output of a XR-E Q4 5B behind a Surefire X series optic for throw or a 5A/5B MC-E for flood is still the sweet spot for balancing output vs color rendition/depth perception/comfort IMHO.
