Nitecore NU43 Head Torch

The world’s lightest 18650 rechargeable head torch, weighing in at just 116 grams

The Nitecore NU43 is the world’s lightest 18650 rechargeable head torch, weighing in at just 116 grams including the built-in 3400mAh battery. Despite its light weight the NU43 has an impressive maximum output of 1400 lumens. Charging is via USB-C port on the side of the light and a USB-C cable is included.

FEATURES OF THE NU43 HEAD TORCH

Constructed from a stamped aluminium alloy front  housing to help aid heat dissipation and a special PC plastic rear housing, which is lightweight yet high strength.

The NU43 includes an extra wide headband for added comfort with a reflective strip to alert vehicles at night.

Utilising a unibody optical lens system with a light transmission of over 94%, the NU43 is specially designed to produce a uniform and soft light and is available with floodlight and spotlight simultaneously. In addition to the white lights there is also an auxiliary red led output to help preserve night adjusted vision.

The NU43 features multiple protection safeguards including an optical sensor, that detects obstructions close to the LEDs that could cause overheating and will automatically lower the brightness and lockout modes.

A unique feature of the Nitecore NU43 is the near-centre of gravity bracket. This design allows for a low rotational torque and short displacement when adjusting the angle of the head lamp, which greatly reduces the pressure on the forehead from the lower edge of the bracket, to achieve a more stable and comfortable wearing experience.

Brightness Levels:
Turbo: 1400 lumens
High: 600 lumens – 10 hrs runtime
Mid: 300 lumens – 15 hrs runtime
Low: 100 lumens – 29 hrs runtime
Ultralow: 8 lumens – 165 hrs runtime
Red light: 10 lumens – 66 hrs runtime
Red flashing: 10 lumens – 90 hrs runtime

Plus SOS and beacon (1400 lumens).

Advanced temperature regulation (ATR) regulates the output of the NU43 according to the working and ambient temperature to maintain optimal performance while preventing the LED from overheating. The outputs are measured in total of runtime, including output at reduced levels due to temperature or protection mechanisms in the design, causing the brightness level to drop down.

Maximum beam distance 130 meters, waterproof to IP68 and resistant to impacts up to 2 meters.

Operation of the NU43 is via a dual summary interface with separate on/off and mode summarys. Four power indicator lights display the remaining battery power.
