Light up letters, commonly seen at events such as weddings, birthdays, and corporate functions, are typically made from high-quality materials such as metal or wood. The choice of material depends on the desired aesthetic and durability. Metal letters, often made from aluminum or steel, are robust and can withstand various weather conditions, making them suitable for outdoor events. On the other hand, wooden letters offer a rustic charm and are perfect for indoor occasions. These letters are then fitted with LED lights, which are energy-efficient, long-lasting, and safe, as they do not heat up like traditional bulbs. The LED lights are inserted into the structure of the letters to illuminate them, creating a captivating visual effect. The letters can be powered by batteries or a power source, depending on their size and the number of lights used.
