I also really like the rainbow PVD, and the Olight UI. The tint I dont care for at all, but my real issue is the Low CRI. Im hoping Olight will suprise us with a High CRI 16340 light, using the Luminus SST-40 LED. djozz has some outstanding info about it, and Im a huge fan of the warm orange tint.

I have built a Convoy S9 shorty with this led. Current 160mA/880mA/1.85A, output on high 350 lumen. That makes the efficiency of this flashlight on highest setting about 50 lm/W which is not bad for a light this warm and high CRI.
Important for the performance of this high CRI SST-20 is how the beam looks like and how the tint/CRI is affected by the (OP-)reflector and lens (the lens of the S9 does not seem to be AR coated, which is nice for very high CRI builds)
The beam is a beauty, …
djozz:
The beam is a beauty, I say 219B-quality:
The light quality in the hotspot:
The light quality halfway the spill:
So compared to the bare led, in such a build you loose a small bit of CRI and the rosiness is a bit less, in fact the hotspot ended up almost on top of the Black Body Line. If you really want to retain the rosiness of the bare led you need to use this led in an aspheric lens flashlight.
