350 Lumens at the LED!  (approx. 280 out the front lumens)

3 output levels (High/Medium/Low)

Uses a single 18650 or 17670 battery only

Fully regulated for constant brightness throughout the runtime

Requires an XP-G reflector, as the XP-G LED will not focus properly in the regular (XR-E) style reflectors.  The exeption to this is the DBS OP style reflectors, the XP-G pills work great in those!
