The Nitecore HA25 UHE Multi-Colour Temperature Outdoor Headlamp delivers a powerful maximum output of 800 lumens with a beam distance of up to 120 meters. It is powered by six dual-core MCT UHE LEDs, providing six primary lighting modes across three selectable colour temperatures:

• 3000K Warm Light – Excellent penetration in rainy, foggy, or low-visibility conditions
• 4500K Neutral White Light – Ideal for a wide range of outdoor activities
• 6500K Cool White Light – Bright and crisp illumination for long hikes or running

The headlamp features Nitecore’s TrueVision multi-faceted optical lens system, producing soft, evenly distributed lighting with excellent clarity. An ultra-low output mode delivers gentle illumination with up to 88 hours of runtime, while the red light mode preserves night vision, reduces insect attraction, and can be used for emergency signalling.

The HA25 UHE is powered by the included HLB1500 1,500mAh rechargeable battery pack and is also compatible with 3x AAA batteries, ensuring flexible and accessible power options. An integrated aluminium alloy heat sink, combined with the rechargeable Li-ion battery, efficiently dissipates heat and reduces internal temperatures, enabling up to 13 hours of stable illumination at 100 lumens.

Operation is intuitive via a dual-button interface: the power button controls on/off and brightness adjustment, while the mode button allows seamless switching between colour temperatures.
