Weatherproof LED Candles are the safe and easy way to add a warm white candle glow to any indoor or outdoor location. This set of 3 pillar candles (4”, 5” and 6”) features a patented LED flame design with flexible flame tip that simulates the movement of real flames. A built-in timer turns them on for 6 hours at the same every night, then shuts them off to conserve battery power. Operates up to 3 months on a set of batteries.
