Reviewers describe the Nitecore NU25 UL as a functional, lightweight headlamp that's a good match for backpacking and outdoor activities. They point to the waterproof build, the essential feature set, and a surprisingly low price. The 400-lumen output struck some as modest, but the consensus is that it performs solidly for ultralight users. Hikers and campers who want reliable, budget-friendly headlamp functionality are the fit.

Sofirn HS21
1 sourceall derived$43as of Oct 10

The Sofirn HS21 is a T-shaped headlamp with an infrared gesture sensor, one spotlight LED, six floodlight LEDs, and three red LEDs. Reviewers liked the hands-free operation and the range of lighting modes, and the floodlight LEDs hit a high CRI at 99. Measured flood lumens didn't match the advertised figures, though. Bracket durability also came up as a build-quality concern. It suits people who want flexible lighting options with gesture control, but anyone who needs the lumen figures to be exact should look elsewhere.

Strengths
  • — Features gesture sensor for hands-free operation
  • — Provides multiple lighting modes including spot, flood, and red LEDs
  • — Rechargeable 18650 battery with USB-C charging capability
Watch-outs
  • — Build quality concerns with bracket snapping reported by some users

How they stack up

Nitecore NU25 400 UL

Against the Silva Trail Runner Free H it is cheaper and lighter, but it gives up the Silva's hybrid battery system and its simpler brightness switching. Among ultralight rechargeable lamps its strength is feature count per gram rather than raw output.

Sofirn HS21

The Sofirn HS21 has a gesture sensor for hands-free operation and is listed at up to 2,300 lumens, against 700 lumens for the Fenix HM50R v2 and 800 lumens for the Nitecore UT27 MCT 800, though its flood output measured below the advertised figure. At 168.53g with battery and headband it is heavier than the Fenix at 78g and the UT27 at 74 g. Its IP65 rating sits below the Fenix's IP68.
