The first reason is the visibility provided by the neon tubes. Secondly, a neon tube is more energy efficient and thus more cost effective to operate than incandescent lighting. A red neon tube provides 5 times the light when compared to an incandescent lamp using the same wattage.
Readability is also important in business advertising .
A neon sign has better readability than an incandescent sign made with the same amount of light output. The incandescent sign will have a blurring effect due to the concentration of point sources of light in a small space. The neon tube has light distributed over a long length of tubing which results in a crisper display. Finally, neon tubing, in a broad range of colors, can be bent into words and graphics and mixed with other media such as vinyl to convey your message in a distinctive presentation. You can have a beautiful, long lasting, cost-effective marketing design, custom built by a neon craftsperson.
