I have got this X-8 and I love it. Nice machined, very throwy and brighter than all the other XM-L lights I have. I must admit all the others use only one 18650 and I don't own a Fenix to compare with. My specimen came with the lanyard and it pulls 1550mA at 4,2 V though (factory tolerances?). The only negative thing I have to mention is the anodising, which seems to be HA-II at best.
Greetings, Pok! Very nice photos! Just a few observations about your review...
You list all the specs on the light but what about quality? How was the machining? Were the threads pre-lubed? What kind of anodizing on the aluminum and did it come with any flaws? Is it waterproof? What about tactile feel of switch and switch boot? Coated lens? Compared directly to the MR52 & TK35 how does it stack up against them in quality and first impression? All the things I'd love to know since this light is actually on my list of must haves in the future and it would also help to make your review even more successful. :)
Also, the mouse-over pic, you should have the Fenix and the single 18650 X8 comparison shot since it would appear that with a single cell the X8 is MUCH brighter than it is with 2 cells (not sure why though). It would show it off at it's best against the benchmark torch.
