Neon sign can be seen in front of bars, taverns, pubs and restaurants. As Neon sign have bright colors and are different in style they catch the attention of pub and bar owners, who display beer neon signs in their establishments. The process of Neon sign is not very easy. A glass tube is bent into proper shape. After this, glass tube is heated so that letters and graphics are bent properly. After this, bent glass tubes are made to cool. Electrodes are attached to the tube ends with leak proof welds. Inert gas is filled through vacuum pumps in glass tubes. You can also fill argon, helium, Xenon and Krypton gas in these glass tubes. When the gases are charged with electricity they each give off a different color. There are several ways to advertise with neon by displaying your company name, company logo, services offered, products offered, decorative borders, etc.

The inner side of a fluorescent light is coated with phosphor. As phosphor receives energy in one form it emits it back in the form of visible light. Fluorescent lights consume greater electrical current, but they produce the bright illumination needed for many different applications.

Neon tubes as well as fluorescent tubes use low pressure and inert gas fill but the striking difference between fluorescent lights and neon light sign is – the light from a fluorescent tube is the light emitted by the internal phosphor coating while the neon light is the colored light that the neon atoms send out directly. It can be said that neon lights use only one step whereas the fluorescent lights use two steps to produce light.

It is believed that Georges Claude, the French scientist, wanted neon to be implemented worldwide as a lighting system as he considered neon lights as lot more efficient than an incandescent bulb. But that did not happen and the fluorescent dominates the lighting system everywhere and neon lights continue to be used only for ornamental and other publicity purposes.
