$60as of May 28

The Fenix HM50R V2 is a lightweight, durable headlamp weighing just 2.75 ounces with 700 lumens output and 377-foot beam distance. Reviewers noted its IP68 waterproof rating and included USB-C charging cable, though some found the activation method requiring a long press rather than single click. The stiff clip, while stable, makes reattachment difficult for children. It's well-suited for technical outdoor tasks but lacks versatility with limited features and no flood function.

  • Bright output of 700 lumens with a beam distance of 377 feet
  • Durable aluminum construction with IP68 waterproof rating

The Sofirn HS21 is a T-shaped headlamp featuring an infrared gesture sensor, one spotlight LED, six floodlight LEDs, and three red LEDs.
