The Fenix TK30 is a white laser flashlight. A Class 3B laser stimulates a fluorescent crystal to create a broad spectrum white light, allowing this flashlight to throw 500 lumens a jaw-dropping distance of 3937 feet (1200m)—that is 3/4 of a mile! The laser light creates a more focused spotlight beam, than a standard LED flashlight, with little spill over light. The tactical tail switch operates on/off and momentary on while the side switch operates the 3 lighting modes. Other features include a battery level indicator and it is IP68 rated dustproof and waterproof. Made for tactical applications where distance is priority, the Fenix TK30 flashlight will not disappoint.
