Aurora Dancing Flame Pillars sell as a set of three wax-dipped pillar candles with a faux flame that flickers just like a real, lit candle! Each candle runs on a six hour timer, then goes off for 18 hours, repeating the cycle automatically each day once they've been turned on. A convenient remote is included for easy on/off use, allowing the candles to easily be part of a larger display. Each requires 2 C batteries, which are not included. Candles measure 3" wide by 5", 6", and 7" high.
