Tea lights are small, cylindrical shaped candles that are about 1 inch tall and 1.5 inches in diameter. They are designed to be used in candle holders, tealight holders, or oil warmers and are a popular choice for creating mood lighting and ambiance in homes, events, and religious ceremonies. Tea lights typically burn for 4 to 6 hours and are made from various wax types, including beeswax, paraffin wax, and soy wax. They are also available in a variety of scents, including floral, fruity, earthy, and spicy, to enhance the ambiance of a room.
