Escape disposable battery hell with this lightweight, rechargeable headlamp designed specifically for runners. Runner-friendly design features include excellent fore-aft balance and a super low profile, which minimizes bouncing and shifting with your stride. In the event you venture away from the trails, a red rear strobe (with on/off switch) will improve your visibility to cars. The path for 50 meters ahead is lit by a strong, ovalized beam from the 60-lumen LED. Keeping the unit fully juiced is as easy as charging your cell phone. (Each charge is good for about 6 hours at full strength.) Settings include full strength, dimming and strobe. The Sprinter is also waterproof to 1 m (3.3 ft). Includes charger and a variety of power adapters for use both domestically and internationally.
