Description
The Nitecore HA25 UHE has a maximum output of 800 lumens from the NiteLab MCT UHE LED’s and is powered by 1x HLB1500 li-ion battery pack (included) or 3x AAA cells.
This versatile headtorch is powered by advanced 12-core MCT UHE LEDs, delivering six primary light modes, each with three adjustable colour temperatures:
3000K Warm Light- perfect for rainy walks and outdoor adventures
4500K Neutral White Light- ideal for everyday practicality
6500K Cool White Light- superb for long hikes or runs
Red light and an ULTRALOW brightness level are included to preserve night vision and reduce eye strain—ideal for night photography, stargazing, or emergency use. All brightness levels are controlled via a dual-button interface for easy one-handed operation: the power button turns the light on/off and adjusts brightness, while the mode button switches colour temperatures. Pressing and holding both buttons activates lockout mode to prevent accidental activation.
