Enjoy the cozy glow of candles without any of the fuss! At this 3" in diameter and 4" in height, this real flame-effect candle isn't so small it disappears into the background, but not so big it dominates the room. This style of flameless candle is capable of being operated by a remote (sold separately). It is turned on and off by a switch on the bottom, which also activates the timer. Luminara Flameless LED Moving Flame Pillar Candles are made with 100% pure paraffin wax, hand poured and carefully designed to look like traditional candles. They are safer to use than traditional candles, since no actual combustion or wax consumption happens. That means no soot or chemicals are released into the air, making them perfect for use indoors. They're perfect for households with small curious children and rambunctious pets. The light is a warm white color encased in a yellow flame designed to be as realistic as possible. It automatically flickers when you turn the candle on, increasing the realism. When using the timer function, the candle will light up for 5 hours, and then automatically shut off for 19 hours. Candles can provide up to 200 hours of runtime before needing to replace the batteries. With proper care, these flameless candles will provide years of lovely, safe illumination.
