This compact non-rechargeable polymer tactical fire light uses a CREE LED rated at 180 lumens that works in conjunction with a high-efficiency deep parabolic reflector to create a usable beam rated at 190 m. The tail-cap switch provides momentary or constant-on functionality. The 1-in. handle diameter allows it to be paired with most third-party helmet mounts for use by emergency personnel. Power comes from a pair of included CR-123 lithium batteries.
