Description

With 300 lumens of power housed in a super compact, watertight body, the Cosmo 300 is perfect for urban adventures and overnighters in the woods. The Cosmo's new, compact body, is more ergonomic with a lower profile for improved balance, and the updated user interface includes a second switch for easy lens selection. In addition, the updated optical efficiency not only provides brighter light, but also saves battery life. And thanks to its watertight construction, the Cosmo keeps lighting the way whether you're forced to bike home in the rain, or you're hiking back to camp in an unexpected downpour.

Replacing my old one (10ys) that only died after battery corroded. Great update with the locking button combo.

    • It works really well
Color: Aluminum

    • Very compact but bright
Color: Aluminum
I like the fact that the overall size is no bigger than a box of matches like anyone would know what size that is. It sits nice and snug to my forehead or hat and with the multiple lighting functions, I get all the light I need where I need it. The locking feature is super too. No more dead batteries from being turned on at the bottom of the toolbox. ... show more

    • Good for the price
Color: Aluminum
Really like it for the weight, i dont think you can find a lighter headlamp (1.9oz total with lithium batteries)that is actually bright enough to use than this. I almost knocked one star because my switch died after a couple weeks. But Black Diamond responded immediately and mailed out a new one right away. ... show more

    • Great looking headlamp but not bright enough to do anything useful
Color: Aluminum
I found this light is very dim... not really helpful for any uses I wanted it for - night runs, night hikes, night climbing, setting up camp or grilling at night. I'm not sure if the light dims as the battery power diminished or what. There are a lot of features, ability to dim the light etc. but not really needed given it's already quite dim. I would have liked to return but missed the return window. ... show more
