Nitecore NU45 Rechargeable LED Head Torch

£67.98

The NU45 rechargeable head torch is a lightweight rechargeable head torch, weighing only 126 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 1700 lumens on the turbo output, which is designed as a boost setting, allowing 23 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 1000 lumens that lasts for 8 hours and four other brightness settings are available as well as two red outputs and two special modes.

To accomplish the lightweight design, the NU45 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 NU45 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.

The 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, 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 NU45, 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. Turbo is accessed by double pressing the power button with the light on and will remain in turbo for 23 seconds or can be exited early by pressing the power button. 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

The auxiliary white modes feature the Ultralow and Flood Low. Ultralow brightness level is accessed by double pressing the power button when the light is off, press the power button to cycle between the ultralow and flood low outputs.

To access the red mode, long press the mode button to turn on in the red ow output. While on, short press the power button to cycle the red low, red high and slow flash outputs.

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.

To change between the modes while the light is on, press the mode button to cycle between the primary white light, auxiliary white light and auxiliary red light.

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 indicate 100-75%, three indicate 75-50%, two indicate 50-25% and one indicates 25-0% 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 NU45 has a built-in 4000 mAh lithium-ion battery that is charged via the USB-C charging port on the side of the torch and can use standard charging or QC fast charging. The NU45 will automatically switch between the charging methods based on the power source. 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 1 hour 30 minutes using QC fast charging or 2 hours 30 minutes using standard charging.

Operational Modes

Primary White Light:
Turbo: 1700 lumens; 172 m beam range*
High: 1000 lumens; 8 hours run-time; 132 m beam range
Mid: 300 lumens; 17 hours run-time; 71 m beam range
Low: 100 lumens; 34 hours run-time; 41 m beam range
SOS: 100 lumens
Beacon: 1000 lumens

Auxiliary White Light:
Ultralow: 8 lumens; 86 hours run-time; 4 m beam range
Flood Low: 25 lumens; 55 hours run-time; 7 m beam range

Auxiliary Red Light:

Red High: 10 lumens; 50 hours run-time; 4 m beam range
Red Slow Flash: 10 lumens

Note: *Only stays in turbo mode for 23 seconds before dropping down due to overheat protection, therefore a constant run-time is not available. The high can be accessed again after it drops down, but if the NU45 becomes overheated it will stay in the lower output until the torch cools.

Tested to ANSI/NEMA FL1 standards with the integrated battery fully charged in laboratory conditions. End user results may vary due to individual usage habits and environmental conditions.
