How neon works: Explainer

Neon offers a bespoke way to enhance any environment with a glow that’s not just visually captivating but also fully recyclable, durable, and immensely versatile. 

It’s steeped in heritage. A Frenchman by the name of Georges Claude first started producing neon as a by-product to their air liquefaction process in 1900. He then demonstrated the first lamps in 1910 at the Paris Motor Show by showing 2 lengths of 12-metre-long bright red neon tubes for the first time.  

How neon works in detail 

A neon lamp is, essentially, a glass tube filled with neon or argon gas – ‘noble’ gases. These are the gases which are inert or un-reactive. 

The atoms of inert gases will rarely form stable molecules by chemically bonding with other atoms; by inert gases, we mean helium, argon, xenon and, of course, neon. Although this is the case, it isn’t difficult to create a gas discharge tube – like that of a neon light. 

To reveal that inertness is a relative matter, an electric voltage should be applied to electrodes at the ends of a glass tube containing the inert gas. When this is done, the tube containing the inert gas will begin to glow. When the tube is switched off, it will contain only ordinary atoms of neon gas. 

When the light is switched on, the voltage will pull the neon atoms apart, causing electrons to become positively charged ions. Being positively charged, the neon ions will move towards the negative electrical terminal at one end of the tube. The negatively charged electrons that remain will go the other way, towards the positive terminal at the other end of the tube. As the excited atoms, electrons and ions bounce around in all directions, they constantly collide with one another, creating enough energy to give off photons of red light in the case of neon and blue light in the case of argon. 

Due to the rate in which the atoms, electrons and ions collide with one another, a constant buzzing of red or blue light is emitted from the tube. When this happens, energy can also be emitted as heat, not just light. Neon lights can get rather hot when in small diameter tubing, but they are still safe to use. 

The discovery and addition of phosphors to tubes and the use of the inert gas argon has allowed the creation of many different colours. In fact, it’s possible to create over 150 different colours, with little limit as to what can be achieved when it comes to signage or artwork.

Neon Signs: Most frequently asked questions

NEON: There is only one type of neon. Hand made from straight lengths of glass that are heated over a flame and blown into while being bent to shape. It’s not made by a machine or mass produced… it’s an art form. 

The very first demonstration of a neon sign in a modern form was in December 1910, by a man called Georges Claude at the Paris Motor Show, who displayed two 12-metre-long tubes filled with the gas. From that point, the world has been fascinated with neon signs and its popularity and uses has evolved over the many years.  

The combination of their striking appearance, nostalgic appeal, and versatility makes neon signs a popular choice for businesses, events, and individuals looking to make a statement. 

At A1DeSIGNS, we have over 120 years of experience in making neon signs and are always training the next generation in the art of glass bending and sign making to ensure that quality products are sent out for years to come. 

We’re frequently being asked all sorts of questions about neon signs and here are some answers to the most popular queries around neon. 

Are neon signs expensive?

The cost can vary depending on factors like size, complexity, and where you’re buying them.

Despite being a completely hand-made product, neon signs remain a cost-effective option in today’s market. Many people find the unique and vibrant look of neon signs worth the investment.

Are neon signs expensive to run?

No, the cost is low – less than your washing machine for the same amount of time, for example. 

When looking at the running cost of neon, you are needing to work out the kWh. This is done by working out the wattage (real wattage) being used by the transformer and converting that into kilowatts. Then multiply that figure by the number of hours the transformer will be running. This is then multiplied by your electricity cost per kWh. 

A cost of neon guide 

If we take our 8kv/18mA wire wound transformer running at 95watts of power. The sign it powered was running for 10 hours a day for every single day of the year. 

  • 95 watts /1000 = 0.095kWh 
  • 0.095kWh x 10 hours per day = 0.950kWh 
  • 0.950kWh x 365 days = 346.75kWh over the year at 10 hours per day. 
  • 346.75kWh is then multiplied by the current cost for your electricity per 
  • kWh. The current average at the time of writing this is 14.37p/kWh. 
  • 346.75 x 14.37p = 4982.78p /100 = £49.82 for the year. 

Are neon signs dangerous? 

When installed correctly, they are no more dangerous than other household appliances. 

Here’s why? 

When installed correctly the voltage from a neon sign is insulated from being touched. If contact is made with a live connection, transformers generally have protection devices that switch the unit off. 

Neon is generally classed as high voltage (above 990v), but the current is low on a neon transformer, in the milliamp (mA) range usually around 18-20mA. The socket in your house although only 240v can be as high as 30amps 30,000mA of current. 

Voltage makes less of a difference in the case of an electric shock, whereas current makes a massive difference, for example static electricity is in the range of 25,000 – 35,000 Volts, but the current (measured in mJoules) is extremely low and not constant. 

Current has the following effect on the body At 20-75mA of current someone would receive a painful jolt and loss of muscle control. 

At 75-100mA of current, ventricular fibrillation of the heart can occur (uncoordinated twitching of ventricles). 

At 100-200mA of current, ventricular fibrillation occurs, often resulting in death. At over 200mA of current, severe burns and severe muscle contractions occur and internal organs can be damaged, and the heart can stop due to chest muscles applying pressure. However, this clamping effect can prevent ventricular fibrillation, greatly improving the chances of survival if the victim is removed from the electrical circuit. 

Are neon signs tacky?

Ultimately, whether a neon sign is considered tacky or not is subjective, and opinions on their aesthetic appeal can vary widely.  

However, neon signage is on an upwards turn in terms of popularity with massive increase in demand for neon signs for bars, clubs and restaurants.

Once again being used to attract the crowds, neon is working its magic and becoming the go to for external signs. Some are taking the trend to the next level by installing these brilliant signs inside to create a retro feel.

Are neon signs plasma?

Neon signs don’t use plasma as the primary means of producing light, but they do involve a similar principle.  

Inside a neon sign, there are glass tubes filled with either neon or other gases like argon, xenon, or krypton. When an electrical current is passed through these gases, it ionizes them, causing them to emit light. This process is similar to how plasma lights work, where gas is ionized to produce light.  

However, neon signs specifically rely on the ionization of gases within glass tubes to create their characteristic glow, rather than generating plasma in the traditional sense.  

Can neon signs be repaired?

Yes. Neon signs can be repaired 

Some common repairs we deal with include replacing broken glass tubes, fixing broken wires or connections, and replacing failing transformers or power supplies.   

If your sign stops working for any reason, turn it off then on again. If this does not correct the issue, turn it off and leave it off, then contact us so we can assist with fixing it.  

It is important to only trust trained professionals with repairing neon signs, as they can be dangerous to work with and require specialised knowledge and tools. * If you cannot bring your broken sign to us – we can come and investigate the fault and more-often-than not make any subsequent repairs on site.

Can neon signs be used outdoors?

This is quite an open question with various different points to consider, based on your specific needs. However, the short answer is yes, neon signs can be used outside as long as you have been provided with the right transformer.  All neon glass is suitable for use outside, if you live in a particularly cold area (North Scotland for example) then you may need your tubes pumped with a certain mixture of gas, but generally the only thing deciding the sign’s use is the transformer it comes with. 

Can neon signs be refilled?

Yes, neon signs can be refilled, but the process is quite complex and requires specialized equipment and expertise. 

When a neon sign is made, the glass tubes are filled with gases like neon, argon, xenon, or krypton, and then sealed. Over time, due to factors like gas leakage or degradation, the gases inside the tubes can diminish, causing the sign to lose its brightness or stop working altogether. 

To refill a neon sign, the sign must first be disassembled, and the old gas removed from the tubes. Then, the tubes are vacuumed to remove any impurities. Next, the desired gas is introduced into the tubes at the correct pressure and purity level. Finally, the tubes are sealed again to prevent gas leakage. 

Refilling a neon sign requires specialized knowledge and equipment, so it’s essential to have the process performed by professionals who are experienced in working with neon signs. Additionally, not all neon signs may be refillable, depending on factors like the condition of the tubes and the type of gases used. 

Can neon signs freeze?

The gas inside a Neon sign will not freeze. If water is on the outside of a tube and is exposed to a cold enough temperature, then this can freeze and can potentially damage / break the sign. 

However, provided a sign is kept running it should generate enough heat at the electrodes to keep the gas ignited and should help prevent the tubes from becoming cold enough to allow ice to form. 

 

How Long Do Neon Signs Last?

To answer the question simply: A long time!

Neon has a manufacturer’s predicted lifespan of 45- 50,000 hours. However, it can last much longer if installed correctly and manufactured to a high-quality standard. A great example is a sign found in America several years ago that had been running for over 70 years. Search Neon running 77 years on Google. 

On average, well-maintained neon signs can last anywhere from 8 to 15 years. However, some can last even longer with proper care.  

Factors such as exposure to weather, dust, and physical damage can also affect their longevity. Regular maintenance, including cleaning and checking for any issues with the wiring or gas tubes, can help extend the lifespan of neon signs.  

Neon is made so that it can run at high voltages, there is no strain put on the product by doing so. Neon can also be run at low voltage; however, this again does nothing to the life expectancy when compared to high voltage. 

It’s also worth noting that glass neon, the only true neon product in existence, does not burn fingers. Correctly assembled and installed, Neon is perfectly safe to touch. The electrodes do get warm, but won’t burn should you touch them, the electrical connection itself should always be covered with rubber caps, called shrouds or electrode sleeves, insulating the electrical connection along with any heat given off. 

Another factor that enhances neon’s longevity is that neon can be easily repaired.

Some common repairs we deal with include replacing broken glass tubes, fixing broken wires or connections, and replacing failing transformers or power supplies.

Neon Sign Safety – Explainer

As neon experts, at A1DeSIGNS, we’re frequently asked all manner of questions about neon. Rightly so, questions about the safety of neon pop up time and time again – so we’ve put together a quick question and answer around the topic of neon sign safety. 

* Firstly, A lot of people conjure their own opinions on the safety of neon signs, without seeking advice from an expert. We are glad when people ask about the safety of neon lighting as we can help to get the correct message across.  

Is neon safe? 

YES; neon signage is incredibly safe to use, providing it is well looked after and treated with respect. Neon light dates back over 100 years to the time – so you can feel confident that modern day neon signs are more reliable and safe than ever before. 

Why do people think neon isn’t safe? 

A lot of people worry about the inert gases that are used to manufacture neon signs. Generally, it’s thought that these types of gases can be harmful if the tubes are damaged and the gases are released into the air. When neon lighting is damaged, the electric charge is instantly switched off, meaning there will be no current passing through the gases. 

Also, neon signs operate at high voltages, typically in the range of 2,000 to 15,000 volts, depending on the sign’s size and design. It’s crucial to hire a qualified professional for installation to ensure the electrical components are handled correctly.

A1Designs commitment to neon safety 

Every neon sign created by A1deSIGNS is done so in-house. Our signs are made from glass tubes and depending on the colour of the sign, a clear, powder coated glass or coloured glass will be used. The signs are then filled with neon or argon gas, which depends on what the final colour needs to be. Once the signs are complete, they are extremely safe and should have a long lifespan if they are well looked after. 

Regular maintenance is important to keep neon signs in good condition. Checking for any damage, loose connections, or malfunctioning components can help prevent potential safety issues.
