Lanterns are portable light sources that have been used for centuries. They typically consist of a light source, such as a candle or a bulb, enclosed in a protective casing made of glass or metal. Lanterns come in various shapes and sizes, making them perfect for outdoor activities like camping or for decorative purposes during festivals. In many cultures, lanterns symbolize hope and guidance. For example, during the Chinese Lantern Festival, colorful lanterns are displayed to celebrate the arrival of spring. Similarly, Japanese paper lanterns are often seen during summer festivals, adding a warm glow to nighttime celebrations.
