The Nitecore HC75 UHE is a high-performance headlamp that delivers up to 3,000 lumens with a 192-meter beam distance using 32 NiteLab UHE LEDs, featuring a 4500K neutral white primary light for comfortable general illumination and an auxiliary red light for night vision preservation, emergency signaling, and reducing insect attraction.

Powered by a replaceable 5,500mAh rechargeable Li-ion battery, the HC75 UHE charges via USB-C and reaches full capacity in 2 hours and 10 minutes. It offers a maximum runtime of up to 84 hours, making it ideal for extended tasks and outdoor adventures.

Built for comfort, the headlamp includes a lightweight, skin-friendly headband with reflective accents for added visibility and a breathable, hollow design for long-lasting comfort. The headlamp also features a 120° adjustable tilt mechanism for one-handed operation and flexible, multi-angle lighting, covering a 100° wide beam.

The HC75 UHE is equipped with dual protection features. One of these is a lockout mode, which prevents accidental activation. To activate the lockout mode, press both buttons for two seconds while the headlamp is off; the headlamp will flash three times to confirm that the lockout mode is enabled. Additionally, the headlamp can be adjusted upwards to help avoid any unintentional activation during transportation. 

The HC75 UHE is controlled by an intuitive dual-button system:

• Power Button: Controls On/Off, brightness levels, Turbo mode, and Ultra-low mode.
• Zoom Button: Switches between spotlight and floodlight, activates the red light, accesses special modes, and displays power status.

Advanced Temperature Regulation (ATR) adjusts the output of the HC75 UHE based on the working and ambient temperatures. This feature ensures that the device maintains optimal performance while preventing the LED from overheating. The output measurements account for the total runtime, including periods of reduced brightness due to temperature changes or built-in protection mechanisms, which may cause the brightness level to drop.

The HC75 UHE has a waterproof rating of IP68 and an impact resistance of up to 2 meters.

The HC75 UHE includes: USB-C to USB-C Charging Cable, Nitecore NL2155HP Rechargeable Li-ion Battery, Storage Case, Top Strap and Spare O-ring.
