It features a tactical tail cap switch for momentary or constant-on operation and offers three user-selectable programs. Delivering a 165-meter beam and a runtime of up to 30 hours on the 40-lumen low setting, this 3.90-ounce light includes a glass lens, a removable pocket clip, and a nylon holster for versatile carrying options.
