The Nitecore HA15 UHE headlamp has a maximum output of 400 lumens (when using NL1411R battery) or 200 lumens (when using an alkaline AA battery) from the 6 x NiteLab UHE LEDs. Choose from an included alkaline AA or the Nitecore NL1411R li-ion battery.

At just 65g (including an alkaline AA battery and headband), the HA15 UHE is lightweight and ideal for outdoor adventures such as camping, trekking and running or more general use such as DIY or back-up emergency lighting.

The light is operated by dual switches on top of the headlamp; the power button turns the light on, off and adjusts the brightness level and the mode button switches between the light modes and special outputs. Press and hold both switches simultaneously for 2 seconds to enter and exit lockout mode.

The headtorch comes with a multi-purpose clip to attach the HA15 UHE to caps, straps or bags and a diffusing stuff sack can convert the light into a camping lantern or store it when not in use. The lightweight, breathable headband has a hollow, anti-slip design with reflective detailing for additional safety.

Advanced temperature regulation (ATR) regulates the output of the HA15 UHE 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 60 meters (using AA alkaline battery) or 80 meter (using NL1411R), waterproof to IP66 and resistant to impacts up to 1 meter.

Includes: 1 x alkaline AA or 1 x NL1411R li-ion battery, headband, clip, diffusing stuff sack.
