This light has a NEUTRAL LED, so the lumens will be slightly lower than the lumens listed below
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.
