I recently received a few Convoy S2+ with high-CRI emitters. So here is a another tint comparison photo. Auto white balance used, but what the camera saw was pretty close to what my eyes were perceiving. I’m very impressed with the 5700k Nichia 219C - almost pure white (with a slight hint of yellow) “daylight” like tint with good colour rendering. The 2700k SST-20 is a nice “sunset” warm tint.
From Left to Right - 5700k Nichia 219C, 2700k Luminus SST-20, 6500k 1A Cree XM-L2, 4500k 4C Cree XM-L2, 3000k 7A Cree XM-L2.
Nice comparison!
I have a Nichia 5700K bought in the Jaxman E3, and its as you said, almost pure white with High CRI. One of the best most pleasant lets I have 
The Luminus SST-20 2700K seems like the Luxeon V2 3000K, the warmest I have and that I like a lot too
Thanks for showing 
I like to contrast warm and cool light in my night photography and the 219C 5700k looked like a good high-CRI option. I chose wisely!
