The highly mobile lightweight build of the Nitecore NU21 makes it a first-class lighting companion for runners. With two lamps delivering up to 360 lumens, your path will be well-lit by a soft, uniform dual beam. 5 brightness levels let you adapt to the time of day and your environment. Switch brightness levels easily by activating the double switch which has distinct controls operable with one hand. A rechargeable 500mAh lithium-ion battery will supply the runtime you need, reaching a max of 37 hours of operation.
Multiple Safety Features
The NU21 features an auxiliary red light which preserves night vision and has excellent signaling capability. Constant-on or slow flashing modes can provide your location to others. The headband is also designed with safety in mind, as it is both reflective and glows in the dark. This will enable passersby to see you even when the light source is not facing them, enhancing your safety.
