Description

Around the house, on the trail or at the campsite, the compact, watertight Black Diamond Cosmo 350 headlamp provides an all-purpose, 350-lumen beam and a red light function to light up the night.

Features
  • Dual-fuel design allows you to power the headlamp with 3 AAA alkaline batteries (included) or the rechargeable BD 1500 lithium-ion battery and charger (not included)
  • Settings include dimming, strobe, red night-vision and lock mode
  • White LED emits up to 350 lumens on max setting, 175 lumens on medium and 6 lumens on low
  • Red LED night vision has dimming and strobe modes, and is quickly activated with the dual-button interface
  • Multifaceted optical lens design
  • Integrated battery meter display shows the percentage of power remaining so you know when to replace the batteries
  • Digital lockout feature prevents accidental use when stored in a pack or pocket as a backup
  • IPX8 waterproof protection rated to operate at least 1.1 meters underwater for 30 minutes—perfect should you be caught in a downpour
  • If headlamp is submerged, water may enter the battery compartment, but it will still operate; it should be completely dried out after use in wet conditions
