Packing a 650 lumen punch in a durable, streamlined, and waterproof package, the Fenix TK22 Flashlight is perfect for camping, hunting, biking, and pretty much any other activity in which serious illumination is a big deal. The TK22 weighs in at just 5. 5oz, and boasts 6 light beam blasting modes, from turbo, which lasts for 90 minutes, to low, which will shine for a whopping 168 hours, to a signal ready strobe. Flip the switch on the butt to turn the TK22 on or off, and adjust modes using the side button. It's also impact resistant, and water resistant up to 2m deep, so you can handle it without kid gloves and not worry about finding yourself stuck in the dark.
