Neon lights rely on the electrode heads at both ends of the light to ignite the rare gas inside the lamp tube under a high-voltage electric field. Unlike ordinary light sources, tungsten wires must be burned to a high temperature to emit light, causing a large amount of electrical energy to be consumed in the form of thermal energy. Therefore, with the same amount of electrical energy, neon lights have higher brightness.

Neon lights have a lifespan of over 10000 hours under continuous operation and continuous electricity, which is an advantage that any other electric light source cannot achieve. Neon lights are made of glass tubes, which can be bent into any shape after firing, and have great flexibility. By selecting different types of tubes and filling them with different inert gases, neon lights can obtain colorful and multi-colored light.
