Flameless wax candles deliver a pleasant, ginger apple scent and energy-efficient LED technology with a natural flicker effect for real wax candles with no mess, no soot and no smoke. Safe around children and pets and on bookshelves. LEDs never need replacing. Four-hour timer automatically turns the candle off and turns it on at the same time the next day. Each flameless wax candle requires three AAA batteries {sold separately} for 150 hours of runtime.
