I read the review from csshih
( https://www.candlepowerforums.com/threads/274113 )
and i wondered about the UV exposured picture from the different cool, neutral and warm white LED's, so I made a picture from some of my LED's, and here are the result:
You can see the warm whites (SST90 and MC-E, Rebel and XR-E) but I'm amazed about the yellow and bright luminescence from the P7, this is a cool white and the SSC P4 with the same shine is a neutral white....

hehe, cool pics! what (peak) wavelength of UV are you using? I'm using a black light bulb ~360nm.

I tried this myself as well, it's weird how the SSC's are so yellow compared to the Crees of similar tint. And how orange anything remotely warm is.

Interestingly the high-cri-warm-white-SSC-P4 in my Ra Clicky emits bright green light when exposed to uv-light.
