UCO candles are custom engineered for use in UCO Candle Lanterns. The candles come in three different configurations – the original 9-hour, dripless white candle, a 9-hour insect-repelling citronella candle, and a 12+ hour natural beeswax candle. All feature high-grade wax formulas that burn clean and free of soot. The candle wicks are specially designed to maintain an even flame height, making them ideal for use in lanterns. UCO candles are equally well suited for to a variety of indoor and outdoor uses, including emergency power outages or simply providing warm, ambient light. Available in economical 3-packs or bulk 20-packs, be sure to keep your emergency kit and/or camping gear stocked with extra UCO 9+ hour candles.
