Looks like a pretty decent light! I’m kind of avoiding 3x18650s now through, prefer the 4*18650 as I have a few sets i can re-use on several lights.

@Maukka: Have a question about your effifacy - you mentioned Acebeam and Olights are pretty good, do you have a website or some spreadsheet where I can see a summary of all your efficacy values? Interested in knowing between Acebeam, Olight and Zebralight, which are the best ones.
