Pros and Cons of Neon Sign

The neon sign is an electric sign lighted by long luminous gas-discharge tubes that contain rarefied neon or other gases. They are used worldwide but in the USA they started using them as early as 1920.

They have sealed glass tubes with electrodes at each end and they are filled with a number of gases at low pressure. They are more efficient depending on the color of the light.

The gases used include neon, helium, argon, mercury vapor, and xenon. They all have different colors.
