This light package contains a OKW light head, 18350 Handheld body and tail cap. It also includes KeepPower 1200mAh 18350 battery 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 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 18350 high drain cells which can be found here. Runtime is about 35 minutes with the supplied 18350 cells.
