The Nitecore NWH20 is a rechargeable work headlamp with up to 600 lumens of 4500K neutral-white light and an 89 m beam distance. Four quad-core UHE LEDs provide spotlight, floodlight and mixed lighting. The ZOOM button adjusts the beam electronically on Low, Mid and High, while Turbo and Ultralow use fixed beam patterns.

Five white-light levels, two red-light levels, SOS, Beacon and red slow flashing cover hands-free work and signalling. The included 4000 mAh WLB40 battery is removable and charges through its own USB-C port in approximately four hours with a 5V/1A supply. Maximum runtime is 51 hours at 40-lumen white Ultralow or 68 hours at 5-lumen red Low; output varies with heat and use.

A 160° adjustable head, anti-slip headband and four supplied hard-hat clips help position the light for inspection and maintenance. The reinforced-composite lamp weighs 149 g with its battery and headband, is IP66-rated and is impact resistant to 2 m. Electronic lockout helps prevent accidental activation during transport. Follow the manual's battery and safety instructions.

Manufacturer figures measured to ANSI/PLATO FL 1-2019 using one WLB40 4,000mAh battery at 26°C. Results vary with batteries and conditions. Runtime is a standard test duration, not a promise of constant peak output. Thermal regulation adjusts output; TURBO steps down during prolonged use. A dash means no value is published.
