The Nitecore NU43 is the worlds lightest 18650 rechargeable headtorch, weighing just 116g (4.09oz). The torch offers a maximum output of 1400 lumens and a beam range of up to 130 meters.

The headtorch has a dual button interface with a power on/off button and a mode button, both having a different shape and feel, making it easy to access the 3 special modes and glide through the 5 brightness levels.

The NU43 features a built-in 18650 Li-ion battery that can be fully charged in just 2 hours. A power indicator can be accessed with a short press of the mode button.

The headtorch also features a near-centre gravity bracket. This design allows for small rotation torque and short displacement when adjusting the headlamp. The bracket is adjustable to 72 degrees and can be adjusted upward quickly, avoiding direct lighting if needed.

This compact and lightweight headtorch is made from durable PC material with an alluminium alloy front housing. It is the perfect headtorch for running, camping, trekking, patrolling and industrial maintenance.

Advanced Temperature Regulation (ATR) adjusts the output of the NU43 based on the working and ambient temperatures. This feature ensures that the device maintains optimal performance while preventing the LED from overheating. The output measurements account for the total runtime, including periods of reduced brightness due to temperature changes or built-in protection mechanisms, which may cause the brightness level to drop.

Includes: NU43, USB-C charging cable, headband.
