The lightweight, high-intensity Fenix HL21 headlamp won't let you down when the weather takes a turn for the worse. The water-resistant construction ensures operation in a downpour.

  • Illuminates objects up to 93m down the trail on high
  • Strobe function is handy for signaling
  • Regulated output maintains consistent light output over the lifetime of the batteries
  • Memory circuit automatically locks the brightness level when you turn the light off so when you turn it back on it's at the same level
