Same great moving action and quality as Luminara! This Mystique Moving Flame set of 2 tealights are made of ivory colored ABS plastic and features a 5-hour timer that can turn the tealights “on” and “off” at the same time every day. A 3-position switch on the bottom of each candle turns it either “on” or “off”, or puts it in the 5-hour timer mode. Since these candles are constructed of plastic, they won’t melt in the summer sun or crack in the winter cold; however, we recommend they be kept away from rain and water. Since these tealights only measure 1.5-inches in diameter by 1.25-inches tall (2-inches to tip of flame), they can be easily placed in small tealight holders or other tight locations. Each tealight runs on a 3V, CR2450 lithium button cell battery (included) and will last about 70-hours.
