Camping after the sun goes down requires light. Unfortunately, those lights normally also attract bugs. Unless you're using the Thermacell Repellent Camp Lantern. This water-resistant lamp produces up to 300 lumens of light, and also repels mosquitos, flies, and other tiny flying pests by heating an insect repellent and releasing it into the air. It can run up to 50 hours on its highest setting — there are three — using just one set of D-Cell batteries, and features a built-in battery life indicator to let you know when you're running low on juice.
