LED tea light candles are ideal lighting options for weddings, vigils, churches, concerts, parties, restaurants, and the home. Completely heat-free and flame-free, these LED candles are a much safer option than traditional candles. They measure 1.8 inches high and can be turned on/off by flipping a switch that is located on the bottom of each candle. The green LEDs flash in a way that simulates a flickering flame, so they create an awesome lighting effect! Batteries are included and installed. Each box contains 12 tea light.
