Klarus HM3 Lightweight Rechargeable Headlamp

Featherweight Performance

The HM3 is built for users who hate feeling a headlamp on their head. Ultralight construction keeps weight to the absolute minimum while still delivering 670 lumens of real, usable output. Wear it all day without remembering it's there.

180-Degree Rotating Head

The fully rotating head lets you angle the beam in any direction — straight ahead for trail running, downward for close work, slightly up for area illumination. One headlamp, four use modes.

Multiple Output Modes

  • High, medium, low for output flexibility
  • Red flashing mode for visibility
  • Tilt and rotation adjustments

USB-C Rechargeable

USB-C charging from any standard cable. Built-in rechargeable battery keeps you running through long days.

Comfortable for All-Day Wear

Soft, breathable elastic headband. Featherweight construction. Designed for runners, ultralight backpackers, and anyone who hates the weight of typical headlamps.

Who the HM3 Is For

The HM3 is built for trail runners, ultralight backpackers, climbers, and anyone who values weight savings — but doesn't want to sacrifice real-world output to get them. Also a great option as an all-day work headlamp where comfort matters more than maximum brightness.

Backed by Klarus's manufacturer warranty and our simple 30-day return policy.
