Electric candles are flame-less and smoke-free, absolutely no fire hazards or burning risks, safe for families with pet or young child. A real tealight can only burns about 5 hours. Our battery operated candles will last at least 50+ hours, which saves you lots of troubles buying bulk of tealights. These tea light candles are perfect for any romantic moments, creative birthday party decorations, & creating a relaxing spa atmosphere. Lights are warm yellow and they do flicker like real candles. Comes in a pack of 10 with battery installed. Do not have a switch for turning on/off. Only light up when placed on water.
