Designed for the Active User
The NU20 is designed to be as convenient as it is capable. At just over two inches in length and weighing under 2 ounces, this little lamp won't weigh you down, making it ideal for camping trips, late night runs, and other active endeavors. Crafted from durable polycarbonate materials, this rugged light is both waterproof and impact resistant, allowing it to endure the wear and tear of the elements and frequent use. The lamp's easily-adjustable headband conforms to nearly any head size and is made from comfortable but tough nylon material.

Internal Power Source
Unlike most headlamps, the NU20 has no need for replacement batteries, instead it has been designed with a convenient rechargeable Lithium Ion battery pack. The potent battery pack can power the lamp on its highest output for 30 minutes and can run its 1 Lumen output for an astounding 100 hours before needing to recharge! The 600 mAh battery is recharged internally via the light's convenient micro-USB charging port and can be recharged up to 500 times before seeing any notable drop in its capacity.
