Excellent capacity: a single aaa battery offers the i3t 2 a max power of 200lm output 10440 rechargeable li-ion battery not included is also supported and can boost the light's max output to 300 lumens. Brand new clip: the clip on the i3t 2 is now stuck between the battery cover and the body -- never worry about falling off and it allows for deeper pocket carry.
