Great review, thanks!
I didn’t understand a word on the video but the written review was translated enough 
. I liked the run times graphs specially the one with the tail cap current measurements.
Impressive that the current draw on the S25LR never drops below 3A which means close to 1,000lm output throughout the whole runtime. Temperature regulation looks very stable.
After owning the klarus XT12GT for a while and given it some real use I realized the importance of stable output in the long run, rather than the initial output.
