Voltaic, the innovative green design company that is best known for its portable solar panels and solar-powered bags, just unveiled a new LED touchlight, and it’s one of the brightest ideas we’ve seen recently. The tiny light is completely waterproof—in the YouTube video after the jump, the lamp is shown completely submerged in a jar of water—and with LED bulbs that range from 50 to 175 Lumens, it’s highly efficient. Best of all, it can be powered by any USB power source. That means that it’s a perfect match for, among other things, Voltaic’s own portable solar panels.

The beauty of Voltaic’s new touchlight is in its versatility; the diminutive light can hang from the ceiling as a pendant lamp, or you can prop it up on a battery pack like a desk lamp. The light is made from lightweight recycled aluminum, making it durable and chic enough for both indoor and outdoor use. And it would be perfect for an emergency preparedness pack in case of a power outage.

Another neat feature of the touchlight is the patent-pending lens, which doubles as a switch. By tapping the lens, you can adjust the brightness of the light, which can be used to light anything from a car or tent to a small room. Using a standard Voltaic USB battery pack, the touchlight can run for as long as 20 hours on the lowest setting or four hours on the highest setting. The new light is available now through the Voltaic website for $35, or it can be purchased as part of a Buy One Give One Solar Lighting Kit, which donates solar panels to villages in the Peruvian Andes.
