With two CR123a batteries, one gets a max of 1080 lumens, and with a standard 18650 (which is probably what is included) one gets 950 lumens. But I wonder if , with a 3500 mAh high drain 18650 one might not get even higher output. (Often, the actual cells inside 18650 3400 mAh and 18650 3500 mAh batteries are the same , but the higher drain battery has a better, more efficient protection circuit).

swimjayDo you have any you recommend? --> 3500 mAh high drain 18650s

WavesterI've had good luck with the LG 18650MJ1 protected 3500mAh from Mountain Electronics, LLC.

swimjayI suspect the primary reason you get more output with the two CR123s is because they're delivering a slightly higher voltage to the LED as compared to a single 18650 (6V for two CR123s in series vs. approximately 4V for the 18650). Not to worry either way, though. Unless you were comparing two lights right next to one another, your eye would never be able to tell the difference between 950 and 1080 lumens. As well, I can't imagine this light is drawing enough amperage, even in turbo mode, to justify needing a high drain cell.

Major_InfidelThis is correct. Higher voltage from 2cr123A than 1 18650. BTW...have this light and difference is not noticed by eye in outdoor environment.
