The TK11 uses two CR123A batteries or one 18650 Li-ion and maintains excellent constant brightness with two output modes. General mode can last for a whole night and can be used for general illumination. Turbo mode is ideal for whenever high-powered light is needed - search and rescue, long-range target identification, etc. This flashlight is great for camping trips or other outdoor adventures that may last into the night.

The TK11 features a premium hard-anodized anti-abrasive finish, toughened ultra-clear glass lens with anti-reflective coating and tactical tail cap switch with momentary-on function. Included with the flashlight are a holster, lanyard, two spare o-rings, spare rubber switch boot, allen wrench, two spare screws, and copper spacer ring.
