FFL and CNQG are owned by the same co and differ only on shipping details; the flashlight is the same. This is the only current source for the black SRK, far as I know.
The black FFL/CNQG SRK uses direct drive on high and PWM on lower modes. It is brighter than the regulated driver version originally reviewed here. It also gets hotter.
The version lightmalls is selling is sand colored and regulated just like the one in the review linked above. This version has no PWM and fewer heat issues but is less bright on high than the DD version sold by FFL/CNQG.
Cheapest source for the sand version is http://www.fasttech.com/products/1601/10000620/1057203-fandyfire-uv-s5-cree-xm-l-t6-1800lm-flashlight-4-x
Only source for the black version is FFL or CNQG. Hope this helps
