The Nitecore HA11 headlamp has a maximum output of 240 lumens from the 2 x NiteLab UHE LEDs and can be powered by 1 x AA (included) or 1 x Nitecore NL1411R li-ion battery (sold separately).

In addition to the white light the HA11 also has a red light, ideal for map reading, emergency response, stargazing and night photography. The ultralight, multipurpose headtorch features a unibody optical lens system, specially designed for reflecting a clear, soft light to protect vision and reduce eye strain.

The headlight is operated by a dual switch interface, with buttons different in shape and touch for quick and easy use. Lockout mode is available to prevent accidental activation.

The lamp sits on a 90° adjustable bracket for angling the light as needed, with a comfortable, lightweight headband. Alternatively, the HA11 can be secured onto the included multipurpose clip for attaching to bags, caps and other accessories.

Advanced temperature regulation (ATR) regulates the output of the HA11 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 90 meters, waterproof to IP66 and resistant to impacts up to 1 meter.

Includes: headband, clip, 1 x alkaline AA battery.
