Maxing out at a tremendous 880 lumens, this compact and easy-to-charge light is a stellar choice for training in low-light conditions or for early morning commuters. The unique lens hits the sweet spot between flood and spot lighting, resulting in a wide field of vision with excellent beam focus.

  • Run time is 1 hour, 20 minutes to almost 16 hours depending on mode.
  • Lens is engineered for a wide field of vision up close, and a focused beam further away.
  • Cree XM-L2 T6 LED produces neutral light for crisp contrast, and excellent projection.
