Nitecore HA27 UHE High CRI Three Color Temperatures Modular Headlamp

The Nitecore HA27 UHE High CRI Three Color Temperatures Modular Headlamp is a premium outdoor headlamp designed for hiking, trail running, camping, mountaineering, search and rescue, photography, and other demanding activities where adaptable lighting and accurate color rendering are essential. Combining multiple color temperatures, high CRI performance, modular power options, and lightweight durability, it offers exceptional versatility for a wide range of outdoor environments.

The HA27 UHE utilizes four dual-core MCT (Multiple Color Temperatures) UHE LEDs, allowing users to select from three distinct lighting profiles optimized for different conditions: 6500K Cool White (CRI 73) – Delivers maximum brightness and long-distance visibility. 4500K Neutral White (CRI 83) – Provides balanced, natural-looking illumination for general outdoor use. 3000K Warm White (CRI 97) – Offers exceptional color accuracy and reduced glare in rain, fog, snow, and low-visibility environments.

The high CRI 97 warm-light mode is particularly valuable for users who require accurate color reproduction, making it useful for navigation, photography, inspection tasks, and situations where distinguishing natural colors is important.

In addition to the primary LEDs, the headlamp features auxiliary red lights, helping preserve night vision, reduce visual disturbance, and provide discreet illumination when operating in dark environments.

Its advanced unibody optical lens system with multiple facets enhances light transmission and beam uniformity, delivering a balanced combination of flood and throw for both close-range work and long-distance visibility.

The HA27 UHE produces a maximum output of 800 lumens and reaches distances of up to 150 metres, offering impressive performance for a compact outdoor headlamp.

Power is supplied through a detachable modular battery system, providing flexibility for different operating scenarios. The headlamp includes the NITECORE HLB1500 rechargeable Li-ion battery pack and is also compatible with various AAA batteries, allowing users to switch power sources when required.

The lighting system delivers up to 65 hours of runtime, making it suitable for extended outdoor adventures and multi-day excursions.

Operation is simplified through a dual-button interface, with each button featuring a distinct shape and tactile feel for intuitive one-handed control, even in darkness or while wearing gloves.

Users can choose from 5 brightness levels, 3 special modes, and 2 red-light brightness settings. Integrated power indicators provide clear battery status information, allowing users to monitor remaining power and manage runtime effectively. To ensure efficient thermal management, the HA27 UHE incorporates a die-cast magnesium alloy heat sink, helping dissipate heat while maintaining a lightweight construction.

The body is manufactured from special impact-resistant and low-temperature-resistant PC plastic, making it suitable for harsh outdoor conditions. The headlamp is rated for 1-meter impact resistance and carries an IPX6 waterproof rating, providing dependable performance in rain and adverse weather.
