The Fenix TK15C hunting/tactical flashlight has an extended reach along with a much-demanded multi-colored output. Imagine having complete target vision up to 656 feet! It has three color options: red for enhanced eye shine, green for better distance performance, and white for all-purpose lighting. It features a durable and fully waterproof design intended for harsh outdoor conditions. It operates on one 18650 Li-ion battery or two CR123A Lithium batteries (not included).
