The Nitecore NU17 is a compact, rechargeable head torch that provides a maximum output of 130 lumens from the central white Cree XP-G2 S3 LED.
As well as the main beam, there is also two red side LEDs that provide low, high and flashing outputs. A red output is useful as it preserves the natural night vision and is less likely to disturb others like white light does. The NU17 also has two auxiliary white LEDs with a high colour rendering index (CRI ≥ 90) and a colour temperature of 4500 K that provides an output of 50 lumens. The high CRI means the beam resembles that of morning sunlight, making colours appear more clearly to the human eye and also reducing eye strain, which makes this mode perfect for night reading and close range activities.
Two push buttons are located on top of the NU17, and can be accessed by slightly tilting the head torch forward as the buttons are half covered to prevent accidental activation of the light. The right power button controls the white LEDs and the left 'R' button controls the Red LEDs. Quick presses of the power button cycles through low, mid, high and off. Quick presses of the R button cycles through constant red low, red high, red flash and off.
With the light off press the power button for one second to activate the white auxiliary light. To access SOS press and hold the power button for 3 seconds with the light on or off. Once on in SOS, press the button again with 3 seconds to change to beacon. Once you have been in any setting for 3 seconds or more, the next press will turn the torch off.
A built in battery indicator will display remaining battery power when the R button is pressed and held with the light off. Three flashes indicates the power level is above 50%, two flashes indicates the power level is below 50% and one flash indicates it is below 10% and should be charged soon.
The NU17 has an integrated 580 mAh lithium-ion battery that is charged via the micro-USB charging port on the bottom of the light. Reveal the port by lifting the dust cover and then simply plug the included micro USB cable into the charging port and the other end into a computer/laptop or a suitable USB adaptor. The charging indicator will go red while charging is in progress and turn green once charging is complete after approximately 2 hours.
The total reflective optical lens provides super wide angle lighting and a soft and uniform beam with 180° illumination for excellent peripheral vision. Additionally, the head torch has a hinged bracket, allowing the light to be tilted and adjusted within a 60° angle. The combination of the wide angel lighting and adjustable bracket makes this great for activities where up close light is needed and helps keep you safer as you can more easily see around you rather than just straight ahead.
