HC75 UHE

Q：What LEDs does the NITECORE HC75 UHE use?

A：The NITECORE HC75 UHE utilizes 8 quad-core UHE LEDs, specially designed for high-efficiency lighting devices such as headlamps. Combined with the TrueVision+ technology and optical matrix lens system with various facets, the NITECORE HC75 UHE delivers a bright yet soft beam with enhanced overall brightness and beam distance.

Q：What is the maximum output and beam distance of the NITECORE HC75 UHE?

A：The NITECORE HC75 UHE delivers a maximum output of 3,000 lumens, a maximum beam distance of 192 meters, and a peak beam intensity of 9,216cd, making it suitable for industrial inspection, night operations, search and rescue, and other high-intensity lighting applications.

Q：Why does the brightness of the NITECORE HC75 UHE decrease after extended use?

A：This is because the NITECORE HC75 UHE features an incorporated Advanced Temperature Regulation (ATR) module. During prolonged high-brightness operation, the NITECORE HC75 UHE will automatically regulate the output according to the working condition and ambient environment to prevent overheating damage, maintain optimal performance, and ensure user safety.

Q：What is the e-focus adjustment function (spotlight / floodlight adjustment) of the NITECORE HC75 UHE?

A：The NITECORE HC75 UHE features NITECORE's patented e-focus adjustment technology. Unlike traditional mechanical zoom systems, the NITECORE HC75 UHE enables seamless spotlight and floodlight adjustment or quick switching via electronic controls, allowing users to precisely tailor the beam according to different lighting needs, from long-distance search to wide-area illumination.

Q：What is the purpose of the e-focus adjustment function (spotlight / floodlight adjustment)?

A：The e-focus adjustment function of the NITECORE HC75 UHE allows quick one-handed switching between spotlight, floodlight, mixed beam, or adjustable beam ratios. The NITECORE HC75 UHE eliminates the need to change equipment in complex environments. Spotlight mode is ideal for long-distance search and rescue, floodlight mode is suitable for close-range and area lighting, while mixed beam provides balanced illumination for general use.

Q：What is the color temperature of the NITECORE HC75 UHE? Why is neutral white light preferred for long-term use?

A：The color temperature of the NITECORE HC75 UHE is 4500K. Compared with cool white light, 4500K neutral white light is closer to natural daylight, offering a softer and more comfortable visual experience that helps reduce eye strain, making it ideal for extended working periods.

Q：What is the maximum runtime of the NITECORE HC75 UHE? Is it suitable for long-term use?

A：Yes. The NITECORE HC75 UHE offers up to 84 hours of runtime at the 40-lumen ULTRALOW level, 32 hours at 200 lumens, and 12 hours at 600 lumens, making it well-suited for extended operation.

Q：Does the NITECORE HC75 UHE come with a battery? What if the battery runs out?

A：The NITECORE HC75 UHE comes with one NITECORE NL2155HP 5,500mAh battery. When the battery is depleted, it can be replaced or recharged directly via the USB-C port on the headlamp. The NITECORE HC75 UHE supports 18W fast charging, requiring approximately 2 hours and 10 minutes for a full charge (9V/2A adapter). The universal USB-C design eliminates the need for additional charging equipment, improving convenience for outdoor and professional use.

Q：Does the NITECORE HC75 UHE feature accidental activation protection?

A：Yes. The NITECORE HC75 UHE features dual accidental activation protection. During transport, the headlamp can be rotated upward to prevent accidental activation. In addition, users can activate lockout mode by simultaneously pressing and holding the ZOOM Button and the Power button, ensuring safer carrying and storage.

Q：What is the IP rating and durability of the NITECORE HC75 UHE?

A：The NITECORE HC75 UHE is rated IP68 for dustproof and waterproof performance, and is submersible up to 2 meters. The NITECORE HC75 UHE also offers 2-meter impact resistance. Constructed from aerospace-grade aluminum alloy with a HA III military-grade hard-anodized finish, the NITECORE HC75 UHE delivers excellent durability and wear resistance, ensuring reliable performance in harsh environments such as heavy rain and fog.

Q：How much does the NITECORE HC75 UHE weigh? Is it comfortable to wear?

A：The NITECORE HC75 UHE weighs only 209g (7.37 oz) (battery included). The NITECORE HC75 UHE features a near-center of gravity bracket design that reduces pressure on the forehead, along with a rear cushioning pad for enhanced comfort. The NITECORE HC75 UHE also supports an optional top strap, making it well-suited for extended professional use.

Q：What applications is the NITECORE HC75 UHE suitable for?

A：The NITECORE HC75 UHE is suitable for industrial inspection, engineering construction, power line maintenance, equipment servicing, search and rescue, caving, and hiking. As a 4500K neutral white electronic zoom headlamp, the NITECORE HC75 UHE allows seamless adjustment between long-range spotlight and wide-area floodlight, delivering stable and professional illumination for high-intensity, long-duration, and complex working environments.
