Now 460 lumen I'm reading, so I guess I'm interested in one. My question is, since it has so many battery options, which do you guys think is the best option? 1x18650? 2x16340's?
You'll get better runtime with a 18650. And being that most of these lights are regulated, it'll be the same lumens whether you're running 1@ 3.7v or 2@ 7.4 Many will advise that a single-cell is the "safer" option.
