Nitecore NU35 Dual Power Hybrid Rechargeable LED Head Torch

The Nitecore NU35 is a dual power hybrid head torch that has a maximum output of 460 lumens from the Cree XP-G3 S3 primary white LED. It is powered by a 590 mAh built-in lithium-ion rechargeable battery, but can also use 3 x AAA alkaline or NiMH batteries.

The lithium-ion battery is charged via the USB-C charging port using the included USB-C to USB-A charging cable. Lift the dust cover on the side of the torch, insert the USB-C end of the cable and connect the USB-A end to a suitable USB power source. The charging indicator beside the main LED will glow red while charging is in progress and turn green once charging is complete.

A full charge takes approximately 1 hour, 20 minutes when charging using an adaptor with a 5 V, 1 A output and the torch is turned off. The torch can be turned on while charging, but charging will take longer and an adaptor with a 5 V, 2 A output will need to be used. The charging of the lithium-ion battery is not affected if AAA batteries are installed in the torch, as they sit in a separate compartment.

The primary light of the NU35 is an ultra smooth TrueVision flood beam that provides constant illumination that eliminates the central hotspot to ease visual fatigue and facilitate a clear view.

As well as the primary LED, there are also two high colour rendering (CRI ≥ 90) side LEDs that provide 22 lumens output of warm white light with a colour temperature of 4500 K, that resembles the profile of natural sunlight thus giving a sharp visual while also reducing eye strain, making it perfect for up close work such as reading. Next to the CRI LEDs are two red side LEDs that are useful for preserving night vision and activities such as night photography, astronomy and wildlife observation.

Two buttons separately control the white and red lights and they are shielded by a plastic cover for physical protection against accidental activation. Four brightness levels as well as two special modes are available from the central LED, a single output is available from the white CRI LEDs and two brightness levels plus a flashing mode are available from the red LEDs.

Single press the power button to turn the primary light on in low, and continue to press within 3 seconds to cycle low, mid, high and off. If left in any mode longer than 3 seconds the next press will turn the light off. Turbo is accessed by holding the power button for 1 second while the light is on. After 30 seconds the turbo setting will regulate its output to prevent overheating.

The side white CRI LEDs are activated by holding the power button for 1 second while the light is off. Holding the button for 3 seconds will activate the special modes of SOS or location beacon. The red side LEDs are operated with the left hand R push button and a single press will turn the light on in low, and continue to press within 3 seconds to cycle red low, red high, red flash and off. If left in any mode longer than 3 seconds the next press will turn the light off.

A built in power indicator light in the button flashes to show the remaining battery power when you press and hold the R button for one second while the torch is off.

The headband is comfortable and adjustable, has a silicone strip on the inside that channels sweat and rain away from the eyes and the new design is hollow to not only reduce the weight, but also provide more breathability and comfort. On the outer part of the headband there are reflective strips, which are excellent for enhanced visibility. Additionally the head torch has a hinged bracket, allowing the light to be tilted and adjusted within a 80° angle.
