BLACK DIAMONDEquipment - Cosmo 300 Headlamp - 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.

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.

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.
