The NU43 rechargeable head torch is Nitecore's (and potentially the world's) lightest built-in 18650 rechargeable head torch, weighing merely 116 grams. It offers two white LEDs as well as a secondary red light, and has an optical sensor that will lower the brightness to low mode if an obstruction is detected too close to the light.
The two high power LEDs output an intensely bright beam of 1400 lumens on the turbo output, which is designed as a boost setting, allowing 30 seconds output at a time in order to prevent the temperature of the torch becoming too high and thus protecting the LEDs. The high output is a constant setting of 600 lumens that lasts for 10 hours and three other brightness settings are available as well as two red outputs and two special modes.
To accomplish the lightweight design, the NU43 has a special PC plastic rear housing which is high strength and low temperature resistant, while the stamped aluminium alloy front housing is rigid, durable and has high efficiency heat dissipation. With ultra smooth TrueVision+ technology, the NU43 utilises a unibody optical lens system for a high light transmission of 94%, which reflects a uniform and soft mixture of spot and flood light that provides over a 100° beam angle, and reduces eye strain.
A smaller red LED sits in the centre and provide constant red or red flashing outputs, which can be directly accessed to preserve your night vision, and is good for wildlife observation, map viewing, stargazing and night photography.
An updated head band designed features the a widened 32 mm thicker band which is also hollowed to reduce weight and increase breathability. It also has reflective properties to help keep you visible and a wider silicone strip on the inside to provide better grip as well as divert sweat away from your eyes. Additionally the head torch has an adjustable bracket with a rotation angle of 72°, however unlike a traditional hinged bracket, this has a rotating axis in the centre which provides a smoother and easier adjustment that reduces the pressure on the forehead and lower edge of the bracket.
Two push buttons are located on top of the NU43, a larger power button and a smaller mode button. The power button turns the light on/off and changes the brightness level. To access the white light hold the power button for one second, and it will turn on in the low mode. Each press of the power button will then cycle through low, mid and high. Ultralow brightness level is accessed by double pressing the power button when the light is off, while turbo is accessed by double pressing the power button with the light on and will remain in turbo for 30 seconds or can be exited early by pressing the power button.
To change between the white and red mode while the light is on, press the mode button to cycle back and forth. Once in red mode each press of the power button will cycle between the red constant and red flash settings. To directly access the red light, instead use the smaller mode button and hold for one second from off. When the light is on in any mode simply hold either the power button or mode button for one second to turn the light off again. Two special modes of SOS and beacon are also available, and can be accessed in any state with a double press of the mode button, and once accessed the power button will cycle between the two with each press. To exit the special modes simply double press the mode button again to go back to the previous output.
Four battery indicators are built into the bottom of the torch and will display remaining battery power when the mode button is pressed once while the light is off. All four lights is approx. 100%, three is approx. 75%, two is approx. 50% and one is approx. 25% and the light should be charged as soon as possible. To prevent accidental activation there is also a lockout function which can be done by holding down both buttons for 2 seconds until the white light flashes 3 times. To unlock do the same again and the light will turn on in the ultralow mode.
The NU43 has a built-in 3400 mAh lithium-ion battery that is charged via the USB-C charging port on the side of the torch. Reveal the port by rotating the protection cover and then simply plug the included USB-C cable into the charging port and the other end into a suitable USB power source. The charging indicators on the top will flash in turn before becoming solid, and once all four indicators are solid the charging will be complete after approximately 2 hours when using a 5 V, 2A adaptor.

Fantastic head torch,well built,lightweight and extremely comfortable.Bought for fishing at night very easy to operate with very good light output.This Nitecore head torch was well worth the money paid.Great service from Torch Direct also would definitely purchase from them in the future.
I’ve owned one of these for about a year now and it is a really well designed, easy to use and robust torch. As a Scout leader, I have seen and tried many torches, and this is my favourite head torch of all time.
The torch is comparatively light and comfortable to wear. The strap is easy to tighten and release. The charging port design is really well thought through and gets rid of the small plastic flap that so many rechargeable devices have (and which ultimately always falls off).
I use the torch in the lowest brightness setting most of the time, which is good for general use. The other settings are great when you need a bit more light. I have rarely needed to use the 1400 lumen turbo setting as the 600 lumen high setting is more than adequate for most cases when you need more light.
There is no bulky battery pack at the back of the strap, which I’ve found in other torches reduces the life of the strap. It is clear that when the strap does ultimately need changing, this will be a doddle.
All in all, a great bit of kit.
