The Original LED Flashlight. One of our most popular lights. The Trek 2 is the perfect toolbox, backpacking, or emergency light. Each provides more than 40 hours of light from 3 AA alkaline batteries plus 160 additional hours of usable light. This 2 LED flashlight is extremely rugged. The Trek will never need a bulb replacement since its twin ultra-bright LEDs last 10,000 hours. Double O-ring seals give this waterproof light an underwater depth rating of 1,000 feet. Comes with a bungee wrist lanyard and rubber glare guard.
