I don't have much time, i will write a few comments, later will post more details.
The led is a xm-l U2 2S from cutter, pure white color, was damaged during soldering, but dedomed with success. Can tell you how to do it with a good success rate. Same reflector, 7135 based driver same current, in a xeno F8V5 host:
Was a normal domed led in the flashlight,a xm-l U2 1A:
580 OTF and 9500 lux
now the dedomed xm-l,
488 OTF and 19450 lux!!!!!
Tint shift to ~4800K-5000K(!!!!) (as i said it is a U2 2S from cutter)
Looks slightly more yellow than 3S tint that i have, i think it is now in this category.
lost a 15% of light(assuming both were performing about the same,can't remember well, but i think they did perform the same in lumen testing before dedoming),got a neutral tint and got more than double increase in lux!
Now this is WOW!
