The Nitecore HC75 UHE E-focus Work Headlamp stands as a benchmark in professional lighting equipment, crafted to meet the most demanding needs of industrial, tactical, and technical environments. Built around a powerful lighting core, the HC75 UHE incorporates eight quad-core UHE LEDs arranged in a matrix layout, producing an extraordinary output of 3000 lumens with a throw distance reaching up to 192 meters. This dense LED matrix sits behind an advanced optical lens system that spans a wide 48.4mm surface, delivering over 100 degrees of beam coverage. The result is a clear, three-dimensional visual field that dramatically enhances spatial awareness and work safety, whether the user is navigating dark environments, working on-site at night, or performing detailed inspection tasks.

This headlamp introduces a new standard in adaptive lighting control with its E-focus system, which allows stepless adjustment between spotlight and floodlight modes. Users can precisely control the balance between focused long-distance beams and broad-area illumination, tailoring the output to meet situational needs. Additionally, the HC75 UHE offers three instantly accessible beam configurations: a Mixed Light setting for general-purpose use, a Floodlight mode for wide, close-range coverage, and a powerful Spotlight mode for tasks that require intense, directional lighting. All of these functions are accessible through a dual-button interface designed for single-handed use, with differentiated button shapes and tactile feedback enabling fast and accurate operation even in gloves or low visibility.

At the core of its power system is a high-capacity NITECORE NL2155HP 21700 Li-ion battery with a capacity of 5,500mAh. This battery is not only rechargeable but also replaceable, and it supports 18W fast charging through a USB-C port located securely on the device. The headlamp can operate while charging, ensuring uninterrupted light for extended work sessions or emergencies. The internal power regulation system includes a highly efficient constant current circuit that maintains stable brightness throughout the battery cycle, while four integrated power indicators provide real-time feedback on remaining battery life.

Nitecore places strong emphasis on the user’s comfort and health during prolonged use, starting with the light’s neutral white color temperature of 4500K. This particular warmth minimizes eye strain and renders colors more naturally, creating a visually comfortable environment for long-term use in confined spaces or detailed work settings. The included headband system enhances this comfort with skin-friendly materials and an ergonomic design. A quick-release bracket equipped with a padded backplate and central weight distribution reduces forehead pressure and prevents fatigue, even after hours of continuous wear. This thoughtful mechanical design ensures both stability and comfort in motion, making it ideal for field engineers, rescue workers, and utility technicians alike.

Durability is another core value embodied by the HC75 UHE. The all-metal body is built from aerospace-grade aluminum alloy, finished with a HAIII military-grade hard-anodized coating for enhanced resistance to scratches and corrosion. Its rugged design is not only impact resistant to drops of up to two meters, but also rated IP68 for water and dust resistance, making it fully submersible up to two meters deep. This level of protection guarantees reliable performance in harsh environments, from heavy rain and muddy construction zones to high-dust conditions in workshops and tunnels.

Beyond its main lighting system, the HC75 UHE also incorporates auxiliary red LEDs, which offer two intensity settings and help preserve night vision or signal presence in the dark. Five brightness levels across the white light spectrum and three special modes offer precise control over power consumption and light output, while the integrated ATR (Advanced Temperature Regulation) module ensures thermal stability by dynamically adjusting brightness to prevent overheating.

Every element of the HC75 UHE has been carefully considered to support a seamless workflow. The intuitive interface, customizable beam profile, balanced weight distribution, and enduring construction all serve a singular purpose: to offer a high-performance headlamp that functions as a true extension of the user in mission-critical environments. Whether employed in a professional utility setting, emergency rescue operation, or demanding industrial task, the HC75 UHE delivers a blend of raw performance, technical precision, and wearable comfort that reflects Nitecore’s leadership in the portable lighting industry.
