Black Diamond says:
After-dark dinners on the tailgate, mid-week dawn patrols or late hikes out from the crag are easily handled by the Black Diamond Cosmo headlamp, a sleek, super-bright headlamp for any outdoor pursuit that runs short on daylight.
The Cosmo features 160 lumens of power and six different lighting modes, including red night vision, that all adjust with a single push-button switch. And with a sleek and modern water resistant construction, the Cosmo keeps shining the way through unexpected storms, afternoon precip and accidental dunkings.
The 2016 Cosmo isn't Black Diamond's most expensive or brightest headlamp. However, at 160 lumens it’s provides an adequate beam while still being small, fairly inexpensive, and practical. With each new revision Black Diamond make, the Cosmo has become brighter and smaller. The unit is now squeezed into a nice rectangular case which makes for compact packing.
The Cosmo features s a nice, big, solid button (ideal for those who dislike 'touch' controls). The lamp takes one click to turn on, and then the next click to turn on the small diffused light. Simple. Further clicks simply cycle through the two. By pressing and holding, the lights can be dimmed or brightened. You also don't need to worry about battery wastage as there's a handy lock mode to prevent it from turning on in your pack.
