The Nitecore HA15 UHE ultra lightweight AA headlamp has a maximum output of 400 lumens at a beam distance of 80 meters with a beam intensity of 1,931 cd from the 6x NiteLab UHE LEDs. This headlamp weighs just 43g and features a lightweight, breathable headband made from a hollow and anti-slip material with a reflective design for visibility - perfect for outdoor activities such as camping, trekking or night running.

The HA15 UHE is powered by a 1x NL1411R 14500 li-ion battery or a 1x Alkaline AA battery - choose the included battery from the drop down menu.

The headlamp is operated by a dual-button interface which features a power button to turn the headlamp on/off and to adjust the brightness levels, and a mode button to switch the light sources and access the special modes such as the location beacon, SOS, and warning flashing mode.

The HA15 UHE features a multipurpose clip that rotates 360° and can be attached to a sling bag, bag strap, backpack or cap brim for diverse use. This headlamp also includes a diffusing stuff sack which can be used to turn the headlamp into a camping lantern or to store the headlamp when not in use.

Advanced Temperature Regulation (ATR) adjusts the output of the HA15 UHE 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.

The Nitecore HA15 UHE has an impact resistance of up to 1 meter and a waterproof rating of IP66.
