2 pieces in a lovely gift package. Sara battery-powered crown light with an LED flame that moves. Both lights have a 2 cm diameter and a height of 25 cm. The LED battery lights have a realistic appearance because they are created from actual candle wax. You can buy a Sirius remote control (art. no. 10000) that can be set to time 2-4-6-8 hours, "ON," or "OFF," which works with practically all Sirius items. The candle has a maximum temperature tolerance of 30 degrees. You need to insert two components. At the underside of each crown light are AAA batteries. There are no batteries supplied. The lights can only be used indoors.
