Nitecore NU33 USB-C Rechargeable LED Headlamp
Triple the Outputs, Triple the Benefit
If you need a headlamp that takes specialization seriously, then make sure you use the Nitecore NU33. With a maximum output of 700 lumens and a maximum runtime of 147 hours, this light is perfect for camping, hiking, and late night running. Combined with an upgraded unibody optical lens system, the NU33's LEDs produce a uniform, soft, white light with various settings and a red light for night vision!
Prevention Features
There's no need to worry about accidental activations or mode switches; with the NU33's Lock Out mode, your light will never accidentally turn out so that the battery never runs out.
