Fenix leads the industry in tactical flashlight solutions that are trusted by law enforcement personnel worldwide and the TK26R Tactical flashlight has been designed with officers in mind [although it's a great light for other tactical users as well as fishermen and hunters]. It offers 1500 lumens of white light, 200 Lumens of green light, and 150 lumens of red light, and is powered by one 18650 rechargeable battery [included] or two CR123 batteries [not included]. The 18650 can be conveniently charged within the flashlight using the included USB Type-C cable. Plus, the TK26R is designed for optimal performance in tough conditions, featuring an IP68 rating, superior temperature tolerance, and a durable A6061-T6 aluminum body.
