The ThruNite 2C uses two CR123 batteries to power a CREE XM-L for an impressive 340 lumens on high. The light also goes much lower than that, all the way down to 0.1 lumens, for up close or low light situations where less is more. On the lowest mode, the light can run for 325 hours.

1:Insert batteries with the positive side (+) toward the head. Tighten the bezel (the 'head' of the light) and tail cap then depress the tail cap button fully so that it 'clicks' and the light turns on.
2: To access Max, you simply tighten the bezel. To access Firefly mode, you just loosen the bezel a little. Lightly depress the button momentarily(dont click it off) and then it will switch to next mode. Loosened Bezel: firefly--> Low -> Medium -> High -> SOS. It will remember the last stage before turning off. Tightened Bezel: Max -> Strobe.
