Review: UK Vizion Headlamp

Amid a sea of compact headlamps lacking significant differences, UK’s Vizion stands out. Not only is it waterproof—UK stands for Underwater Kinetics—but the bulb is mounted along a battery-pack cylinder that rotates like a socket rather than on a hinge. This makes the lamp more streamlined and incapable of breaking from its mount. I took the Vizion into a waterlogged Crystal Cave this past summer, and despite getting soaking wet and covered in mud, it worked like a charm. 120-hour burn time on 3 AAAs (included), high and low settings, and a red night filter give it competitive base features. You can also remove the cylinder and use it as a lantern. $30; ukinternational.com.
