This light package contains an OKW light head, 18650 Handheld body, and tail cap. It also includes two KeepPower 3500mAh 18650 batteries and a Nitecore D2 charger. While lumen output is only 680 lumen the throw is about 400% greater than the M600DF. This light head is best suited for situations where the extreme throw is needed.
Lithium CR123 cells are not supported and if used will cause the cells to heat up and possibly explode or catch fire. We recommend the KeepPower 18650 high drain cells. Runtime is about 70-75 minutes with the supplied 18650cells.
