The latest model of the popular Nitecore UT27, the 2024 version has a maximum output of 800 lumens from the UHE LED and is powered by an included 1500mAh li-ion battery pack with a built-in USB-C port. Alternatively, the headlight can use 3 x readily available AAA cells (not included).

As with its predecessors, the UT27 2024 offers dual primary lights including cool and warm white outputs, plus an auxiliary red light. This combination of modes makes the headlamp ideal for various outdoor activities, such as running, camping and emergency use.

The dual switch interface allows for independent control of the 2 colour temperatures, providing quick and easy operation. Both buttons can be pressed simultaneously to enter and exit lockout mode when the headtorch is not in use to prevent accidental activation.

The headband features a new weave structure, making it more elastic and breathable. It stays firmly in place, wicks away sweat and is comfortable to wear for long periods of time.

Available in black with yellow headband or white with grey headband.

Advanced temperature regulation (ATR) regulates the output of the UT27 2024 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 168 meters, waterproof to IP66 and resistant to impacts up to 1 meter.

Includes: Nitecore HLB1500 1500mAh li-ion battery, USB-C to USB-C charging cable, diffusing stuff sack.
