Nitecore NU27 Rechargeable LED Head Torch

The Nitecore NU27 is a compact rechargeable head torch which provides a maximum output of 600 lumens and a red light designed for preserving night vision.

Featuring a cutting-edge 8-core NiteLab MCT UHE LED arranged in a matrix, the NU27 boasts an industry first. With Ultra High Efficiency (UHE) technology, this head torch offers enhanced brightness and longer-lasting light while consuming less energy. The Multiple Colour Temperatures (MCT) feature offers three options - neutral white (4500K), warm white (3000K), and cool white (6500K) - meeting a variety of outdoor lighting needs. At any colour temperature the NU27 features a 50.3 mm light emitting surface which provides clear, three-dimensional illumination for enhanced visibility.

The NU27 also features an auxiliary red light which is useful for activities such as night reading, astronomy and wildlife observation.

Two independent switches are located at the top of the head torch, a power button and a mode button, for easy operation. Seven outputs are available in the white light with the ultra low output allowing for up to 57 hours run-time and two special modes of SOS and beacon. The red light offers three outputs, including a slow flash output.

To prevent accidental activation during transportation the NU27 features a lockout function.

The NU27 has an integrated 850 mAh lithium-ion battery that is easily charged via the USB-C charging port on the side of the head torch. A built in power indicator light on the side of the torch flashes to show the remaining battery power and the charge level.

At just 56 grams, the NU27 is incredibly lightweight and compact. Its bar-shaped design ensures a snug fit against the forehead, while the center of gravity keeps it compact. The elastic, breathable, and skin-friendly headband is also reflective for added safety.

The versatile multi-purpose clip can be positioned in various directions and easily attached to a hat, backpack, or shoulder.
