How Do You Troubleshoot A Neon Sign?

Do neon lights go bad?

Luminous neon glass tubes in the neon signs typically last about 8 to 15 years.

If put in the right environment and well-maintained, then you could get your money’s worth.

Coatings last for up to 7 to 10 years, depending on the sign’s brightness and usage..

Do neon signs burn out?

Today, neon signs suffer from the dreaded burnout, as either the entire sign will stop glowing or only a section of the sign. Some of the most common issues related to commercial neon signs: Electrical wire burnout: Close to 80% of neon sign burnout involves the electrical wires.

What causes a fluorescent tube to flicker?

When a tube or CFL bulb starts flickering, the cause is often worn out electrodes inside the bulb. They weaken the electric signal, and the bulb often glows normally at the extremities but darkens in the middle. That’s also a possible symptom of a malfunctioning ballast, but it’s easy to tell the difference.

What voltage does neon light require?

Neon lamps are recommended for 110 volt AC, 220 volt AC, and DC applications in excess of 90 volts. The lamps are available in miniature and sub-miniature sizes.

How do you test a neon sign?

Turn the sign on by flipping the power switch of the outlet that the transformer is plugged into. Look at the neon sign that is plugged into the transformer. Look for flickering of the light (other than the initial flickering during the warm-up phase of the neon gas).

Why is my neon sign flashing?

Low power will cause a blinking or flickering neon light. You may need to use a step-up transformer if the voltage to the light is not high enough. Use a multimeter to check the voltage on all electrical spots.

Is it better to leave neon lights on?

The answer is yes. Although it may seem counter-intuitive, leaving your neon sign on 24/7 will make it last longer. The electricity cost will be minimal. If you touch a neon sign, you will find the glass is not hot like a re incandescent light bulb because it does not use a filament, so there is no wasted energy.

How do you fix a flickering neon light?

Mercury in new neon signs may have yet to turn into vapor. If that’s the case, leaving the sign on for a few days should solve your flickering problem. If you don’t want to wait a few days, you can turn the sign off and shake it vigorously to see whether you can loosen up the mercury, so that it becomes vapor quicker.

Do neon signs make noise?

There are a couple of potential sources for buzzing noises. First, you have to understand that most Neon signs are powered by very simple high-voltage transformers. Secondly, the tube itself will create some noise, particularly for signs that are fairly high power.

How long will neon signs last?

between eight and 15 yearsMost neon signs are expected to last between eight and 15 years, although many continue to function for much longer than that. Leaving a sign switched on for prolonged periods can shorten its lifespan, and leave it at risk of overheating or sustaining damage from electrical surges.

How do neon sign transformers work?

Neon signs use neon gas that is inert in nature. These signs are made up of tubes that are filled with this gas. This tube is supplied with high voltage obtained from the transformers. The high voltage supplied by them increases the kinetic energy of electrons in the neon atom.

How does a neon light work?

Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases. … A high potential of several thousand volts applied to the electrodes ionizes the gas in the tube, causing it to emit colored light. The color of the light depends on the gas in the tube.

Is it expensive to repair a neon sign?

If your prized neon sign stops illuminating your display area, there are two possible culprits. … The cost of repairing a simple break runs about $50 if neon and $60 if it had argon gas, as the tube has to be cleaned prior to being repaired.

Why does my strip light flicker?

When the light starts flickering, this is probably what is wrong, so the starter will need replacing. … This is basically a round plug that fits into a hole in the light’s casing. Check to see if the plug is firmly in place. If it is, it will need replacing.
