As mentioned in the review thread for the PT10, samples sent contained XM-L, retail inventory I have show XM-L2.
It seems that all LEDs I've tested glow under UV, some more than others. Nitecore CU6, advertised as 365nm.
Turns out Rayus was able to contact a manager from their LED supplier and confirmed that the Nichia is in fact 5000K and 83 CRI
Late to the game, here is a pic of the Nichia NCSW119 vs NVSL119 but would be identical to its 219 brother from top view. You can see the “C” has a smaller die than the “V”
Other things to note:
“C” Vf (L: 3.0-3.4V, M: 3.4-3.8V) and max current is spec’d at 700mA
“V” Vf (L: 2.7-3.1V, M: 3.1-3.5V) and max current is spec’d at 1500mA
