These candles are safer than the real tea lights, but the "flame" sets the same mood. The rechargeable tea light candles are wireless (rechargeable battery) and their long-lasting charges give up to 10 hours of flickering light, producing a cozy, warm, candle-lit space for entertainment, atmosphere, or decoration. Â Because they are cool to the touch, they are easy to use in places where it may not be practical to have real candles. When not in use, place the Candle Lights on their convenient charger base that doubles as a storage holder.
