Neon tube lighting

Neon tube lighting involves filling a glass tube with neon gas and applying an electric current. The electric current energizes the neon atoms, causing them to emit a bright characteristic glow—usually red-orange. Different gases or coatings inside the tube can produce various colors. The glow results from electrons exciting the gas atoms, and as they return to normal energy levels, light is emitted. This type of lighting is often used for signs and decorative purposes due to its vibrant colors and long-lasting, low-energy operation.
