Lilin is a special substance made from wax that can be lit on fire to give off light. It is usually in the shape of a candle or a stick and has a wick in the middle that you light with a match. When you light the wick, the heat melts the lilin and it starts to burn, giving off a warm glow. Some people use lilin to make their homes smell nice by adding different scents or essential oils to the wax. Lilin has been used for a long time and is a way to bring light and warmth to dark places, especially at night when the sun goes down.
