The chemical element known for its use in light bulbs is tungsten. Tungsten is used to make the filaments in incandescent light bulbs due to its high melting point and excellent conductivity. It can withstand high temperatures without melting, making it ideal for producing light when electric current passes through it. Discovering tungsten's properties in the 19th century revolutionized lighting technology, leading to broader applications in various industries. Its durable nature also makes it suitable for use in other electrical components, such as halogen bulbs and high-intensity discharge lamps.
