3200-lumen high-output headlamp with red light, 21700 battery, and USB-C — for demanding outdoor use
The Sofirn HS43 is built for users who need serious headlamp output. Delivering 3200 lumens from a 21700 battery, it's one of the brightest headlamps in Sofirn's lineup — powerful enough to light up an entire campsite or work zone. The 21700 cell provides significantly more capacity than 18650-based headlamps, translating to longer runtimes across all modes without sacrificing output.
Like its stablemates, the HS43 includes a 660nm red light option for night vision preservation, making it suitable for astronomy, night hiking, and wildlife observation alongside its high-output white beam. Six modes cover everything from low moonlight to full-blast turbo, and USB-C charging keeps the 21700 battery topped up conveniently in the field or at home.
At $47, the HS43 sits at the premium end of Sofirn's headlamp range, justified by the higher output and larger battery. The aluminum construction is robust enough for outdoor abuse, and the headband system distributes the slightly heavier 21700 weight comfortably. For trail runners who need to see far ahead, construction workers lighting up large spaces, or campers who refuse to compromise on brightness, the HS43 delivers raw output that few headlamps at this price can match.
