<p>The Cosmo 350 Headlamp from Black Diamond is a great all-rounder that should not be missing from any of your trips. If you can not part with a tour on the rock, just have to get in again, but the approaching darkness threatens to put a spoke in your wheel, then the Cosmo is perfect.&nbsp;</p><p>It is a real lightweight and brings 350 lumens in its revised new, compact and slim housing. It has enough power to light your way in most situations.</p><p>At its highest setting, visibility extends to 75 meters and the lamp can deliver this power for 24 hours. The optical facet lens optimizes the ratio of luminosity to battery life. If you want to save even more battery, however, the lamp can be dimmed to lower lumina. If you're out in the woods at night, you can also turn on red light mode to avoid blinding animals.</p><p>Even the heaviest rain doesn't bother the lamp. With an IPX8 rating, it's waterproof - it won't even be shocked if it falls into the water. A lock mode prevents the lamp from turning itself on in the backpack and you end up without light.</p>
