The NU20 is a upgraded version of the original NU25, with usb C charging and the lighter weight strap
The Nitecore NU20 Classic headlamp has a maximum output of 360 lumens from the NiteLab UHE LED and is powered by a built-in 500mAh li-ion battery.
In addition to the primary white light, the headtorch has dual auxiliary lights including a high CRI white light for accurate colour rendition and close-up illumination, and a red light to effectively preserve night vision and for emergency use.
With the same operation as the original version, the NU20 Classic has a dual button interface for fast and easy operation. The power button controls the primary white and auxiliary white light and the R button is for the red light. Press and hold both switches for 3 seconds to enter and exit lockout mode to prevent accidental activation when not in use.
