Ideal for backpacking, mountaineering, snow camping and other outdoor pursuits, this classic lantern provides cozy heat and natural light for up to 9 hours (per candle). Surrounded by a sturdy metal frame and a glass chimney, the candle is lit in a flash—slide the chimney down and light the exposed wick. As the candle burns, the spring-powered tube pushes the candle up for a reliable, constant flame. Monitor the candle for remaining burn time through the viewing slot on the side of the lantern.
