Aside from an overly complex user interface (tattooing instructions on the back of my hand solved the problem), I like the Black Diamond Icon. Review coming, for now let’s do an iconic helmet mount. Not much to it, though unlike our previous system (Chapter 1) the lamp ends up semi-permanent on the helmet rather than enjoying optional bracketry.
Icon weighs total of 226 grams (8 ounces). That’s fairly reasonable mass to lug around on top of your head (combined with helmet at 584 grams, Salomon MTN). The retail box includes an extension cord that enables stowage of the battery in your jacket pocket, a nice option in case of cold temps or abused neck muscles. You can make the helmet battery mount optional and easily reversed by attaching with duct tape and the goggle loop instead of double sided tape as we did here. You could make the entire mount optional by using the headband strap as pictured above, only improve it with tape so you’re not depending on sometimes too minimal headlamp mounting clips. In my case, Icon is lightweight enough to not bother me when on my helmet.
