Neon signs can burn out, this is where all or part of the sign will stop glowing. There are various causes of this burnout. Bad transformers:- Neon signs glass tubes are illuminated by the use of transformers.
If the transformer fails, the sign will not light up. Due to the high voltage required to power a neon sign and the high temperatures involved, electrical wires can fail. This electrical wire burnout can result in all or part of the sign to stop illuminating. Gas tube failure:- The glass tubes of a neon sign contain an inert gas and a droplet of mercury, the mercury vapor produced gives off Ultraviolet light. If the Neon gas tube fails part of the tube can lose its brightness.
Neon signs are fairly efficient. The reason they look so bright is that all of the output is focused within a small wavelength band of light. If you continuously run a sign for 12 hours, a foot of red neon sign would typically use about If you are always having to send your traditional neon sign back to the manufacturers due to burnout problems you are going to not only be paying for the repairs but also could be losing business by not effectively advertising and drawing custom in whilst your sign is out of order.
You should definitely consider changing your traditional glass tube neon lamps with an LED neon lighting solution. These new-age modern neon lamps use the latest in LED technology to provide you with a much brighter light output than traditional neon lights do. These LED neon signs are also vastly more efficient than traditional neon lighting signs.
They have little wasted energy as they give off little heat and therefore are safer in terms of burns and accidental fires. Traditional neon, constructed with a glass neon tube also presents a breakage risk. This site uses cookies and by continuing to browse it you are agreeing to our use of cookies.

There are two main ways of producing other colors of light besides the orange-red of neon. One way is to use another gas or a mixture of gases to produce colors. As mentioned earlier, each noble gas releases a characteristic color of light. For example, helium glows pink, krypton is green, and argon is blue.
If the gases are mixed, intermediate colors can be produced. The other way to produce colors is to coat the glass with a phosphor or other chemical that will glow a certain color when it is energized. If you see a clear light glowing in a color, it's a noble gas light. Another way to change the color of the light, although it's not used in light fixtures, is to control the energy supplied to the light.
While you usually see one color per element in a light, there are actually different energy levels available to excited electrons, which correspond to a spectrum of light that element can produce.
