You’re right, I hadn’t considered the complication that might be added with the built in charging. That’s not a feature I feel that’s necessary. I figured that there was no way this thing is putting out 2000lm, especially coming from a LB emitter lol. OK, so what’s a good ‘host’ to start with that is physically larger than a C8? I don’t mind staying with 1x 18650. I really like the C8 and I only have medium sized hands but I think it’s slightly too small. Resting my index finger up on the heat sink instead of having a more natural full grip on the tube is slightly annoying.
