Equipped with a revolutionary MCT UHE triple color temperature system with exceptional CRI indices (97/83/73), the Nitecore HA25 UHE transforms your night vision according to weather conditions. This trail headlamp combines TrueVision+ technology offering light transmission superior to 94% and lighting angle superior to 100°, dual power supply (HLB1500 USB-C battery or 3 AAA batteries), maximum output 800 lumens over 120 meters and weight of only 65-91g, trail and camping versatility united in an ultra-lightweight format certified IP66 with multi-position clip and diffusion bag included.

MCT UHE and Intelligent Weather Adaptation

Dense fog, heavy rain, blinding snow or clear skies, your lighting adapts instantly. The warm white 3000K (CRI 97) offers excellent penetration in foggy and rainy weather while avoiding glare and reflection caused by snow thanks to its true color rendering. Switch to neutral white 4500K (CRI 83) for versatile natural vision or cool white 6500K (CRI 73) for maximum range on long hiking and night running routes. TrueVision+ technology with light transmission superior to 94% guarantees every lumen counts, while the lighting angle superior to 100° offers wide and clear vision to anticipate obstacles and terrain. 4 brightness levels per temperature (Turbo 800lm, High 450lm, Medium 280lm, Low 100lm, Ultralow 6lm), auxiliary red light to preserve night vision and avoid insects, SOS/Beacon/Slow flash modes for emergencies, 15 total modes adapted to every adventure phase.

Camping Lightness and Energy Flexibility

The multi-position clip attaches to cap or backpack strap for instant hands-free lighting, the diffusion bag transforms the headlamp into auxiliary lantern for camping, the 65g weight with headband (91g with battery) becomes completely forgotten even on extended outings. Revolutionary dual power switches between HLB1500 USB-C rechargeable battery for daily outings and 3 standard AAA batteries for long-duration expeditions without electricity, zero energy anxiety. 4 light indicators display precise battery level for timely replacement, lock mode prevents accidental activation during transport, thermal protection regulates power for optimal performance, IP66 certification resists splashes and rain. Trail and camping equipment that adapts to your adventure rather than the opposite.

Operating Instructions

Power Button / MODE Button: The HA25 UHE has a dual system for total temperature and brightness control.

Power ON/OFF: When the light is off, press and hold the power button for 1 second to access Neutral white LOW mode. When the light is on, press and hold the power button or MODE button for 1 second to turn it off.

ULTRALOW mode activation: When the light is off, press the power button twice to access Neutral white ULTRALOW mode.

Color temperature change: When main light is on, briefly press the MODE button to cycle through: neutral white light – warm light – cool white light. After switching from neutral white to warm, if no operation is performed for more than one minute, a brief press on MODE button will return directly to neutral white (skipping cool white for this cycle).

Brightness level adjustment: When color temperature is activated, briefly press the power button to cycle through levels: LOW - MEDIUM - HIGH.

TURBO activation: When color temperature is on, press the power button twice to activate TURBO mode of current temperature. Briefly press either button to return to previous level. Note: TURBO mode cannot be activated with AAA batteries. TURBO level will decrease to prevent overheating during prolonged use.

Auxiliary red light: When the light is off, press and hold the MODE button for 1 second to access Red LOW mode. When red light is on, briefly press the power button to toggle between Red LOW and Red HIGH.

Special modes (SOS/Beacon/Slow flash): Regardless of lamp state, press the MODE button twice to access SOS mode. When a special mode is activated, briefly press the power button to cycle through: SOS - BEACON - SLOW FLASH. Press the MODE button twice to return to previous state.

Lock/Unlock: When the lamp is off, press and hold both buttons for 2 seconds until the lamp flashes 3 times to indicate Lock mode access. In Lock mode, all levels and special modes are unavailable, and the lamp will flash once to indicate this state. To unlock, press and hold both buttons for 2 seconds until Neutral white ULTRALOW mode is activated. Note: Lamp unlocks automatically when replacing batteries in lock mode.

Remaining power indicator: When the light is off, briefly press either button to light up indicators in turn and turn off after 2 seconds. Status: 4 constant = 75-100%, 3 constant = 50-75%, 2 constant = 25-50%, 1 constant = 0-25% (recharge or replace).

Thermal protection: The mechanism regulates power according to operating conditions and ambient environment to maintain optimal performance.
