The centre, high-output LED throws a focused beam. 2 side LEDs fill it in with flood lighting. You can dim the Cosmo in either mode to set the right light for the task at hand. An auxiliary red LED lets you check maps without nuking your night vision.

  • Settings include spot, flood, dimming, strobe, red light, and flashing
  • Glove-friendly switch for easy use in any weather
  • IPX 4 waterproof rating shrugs off falling and windblown rain
