Featuring a sleek design and ample feature set, the 70-lumen Black Diamond Cosmo headlamp is equally at home cooking dinner at the campsite or rappelling off a multi-pitch route after the sun goes down. Standard distance and proximity modes, both dimmable, are complemented by a red night vision mode-extra handy when waking in the middle of the night-and all modes are accessible via one simple-to-use button. And with a housing built to withstand sprayed water from any angle, the Cosmo is ready to brave nearly any storm you may encounter on your adventure.

  • 1 DoublePower LED, 2 SinglePower white LEDs and 1 SinglePower red LED emit 70 lumens (max setting)
  • Settings include full strength in proximity and distance modes, dimming, strobe and red night vision Red night vision mode has proximity and strobe settings, and activates without cycling through the white mode
  • Sleek, low profile design uses 3 AAA batteries (included)
  • Protected against splashing or sprayed water from any angle (IPX 4)

Rated 5 out of 5 by Great headlamp The cosmo does everything I need - superbright and lower light level function. red light. flashing. Compact, easy and loads of features. January 1, 2014
Rated 5 out of 5 by Product has great features Headlamp was bought as a gift so I haven't actually used it myself but its recipient thought it would be perfect for his purpose (which is walking his dogs at night). He was very pleased with its features. December 26, 2013
Rated 5 out of 5 by Perfect headlamp The staff at black diamond was very helpful in choosing the right headlamp for myself and my collegues. We are OBGYNs and need the headlamp to use for pelvic exams/procedures in low resource settings and the Cosmo with the 70 lumen light works perfectly. You can also angle the light to directly visualize what you need to see. I love it and so do my collegues. Thank you! December 2, 2013
Rated 3 out of 5 by Good headlamp but turns on too easily I like all the features and brightness of this headlamp, but I find that it's very easy for it to be inadvertently turned on when it's in my pack. I put it in a plastic bag to protect it from moisture. Sometimes I'll notice it's turned on just from being jostled in my pack. Also the battery compartment is a bit touchy and the batteries pop out a bit too easily. October 3, 2013
Rated 5 out of 5 by Great headlamp, excellent customer service I ordered this headlamp and have been very impressed with it. Its is very bright at 70 lumens, but still has excellent battery life at the brightest setting. Its easy to operate, and I like that turning on the red light doesn't require cycling through the normal white lights. After about one month of having the lamp, the switch on the top stopped responding. It would no longer turn on/off or switch light modes. I contacted black diamond customer service and they were very helpful. I sent it back and received a brand new one for free. Great product and great customer service! June 17, 2013
Rated 5 out of 5 by Quality product and customer service!!!!! We needed something hard working and quality. Excellent product! May 20, 2013
Rated 5 out of 5 by Good for the winter Since last December till May I used this kind of BD headlamp in the Arctique and in the chic-chocs mountains Québec and I still use the same batteries and the light still very strong ! May 17, 2013
Rated 5 out of 5 by One in every Pack Whether it is an alpine start up a mountain, that ski tour that went a little longer than expected, a late night float down a river, or a night around the campsite, I am glad I have my Black Diamond Cosmos in my pack. Shines bright and long! May 17, 2013
