I do like the idea of 18650 fed hi cri, certainly around 95 cri!! However, even though my eyes can cope when used alone. Colours do look nice, the xp-l2 4000k to me is very yellow. Now while colours look great, whites,creams etc start to look smoke stained.............me not likey.
So for now jury out, would like to try 4500k or even 5000k as mentioned for a cleaner beam if makes sense. I know subjective....................I kind of get a little frustrated, take the EDC+ and D4 4000k g2's, real nice warmth to it but lower CRI. Given the choice, the g2 4000k wins hands down regardless of lower CRI as my eyes are just so much happier.
I would like to see George consider the 219c 4000k which is a little towards yellow, but for me a lot easier on the eye than the xp-l2 4000k
