Are Neon lights made of Neon?

Have you ever wondered if neon lights are actually made of neon? Believe it or not, real neon lights glow reddish-orange in color. This blog post will guide you through the intriguing process of how these captivating lights are created and what role neon plays in their luminescence.

Ready to enlighten yourself? Let’s discover the brilliance behind neon lights!

Key Takeaways

  • Neon lights are not solely made of neon gas. Other gases, such as argon, can be used to create different colors in neon lights.
  • The glass tubing used in the production of neon lights is heated to a high temperature to make it pliable for bending into various shapes and designs.
  • Neon gas is used in traditional neon lights and produces a reddish – orange glow when ionized with electricity. Other gases can be used to create over 150 different colors in neon lights.

How Neon Lights Are Made

To make neon lights, glass tubing is first created and then heated to a high temperature.

Creating a glass tubing

The first step in the creation of neon lights involves making a glass tubing.

  1. The process kicks off with a straight, clear glass tube.
  2. The length and diameter of the tube are selected based on the desired size and design of the neon light.
  3. Once these parameters are established, workers heat up a specific area of the glass tubing until it becomes pliable.
  4. This heated section is then carefully bent into intricate shapes to form letters, numbers, or decorative designs.
  5. Attention to detail is paramount as cracks or flaws in the glass can lead to gas leaks that would render the neon light ineffective.
  6. After a satisfactory shape has been achieved, electrodes are appended at both ends of the tubing.
  7. Lastly, the formed glass tubes need to cool down naturally before filling them with gases to avoid misshaping or damage from sudden temperature changes.

Heating the tubing

  • The glass tubing used in the production of neon lights is heated to a high temperature.
  • The heating process helps to soften the glass and make it more pliable for bending into various shapes and designs.
  • This step is crucial in creating the desired shape and structure for the neon light.
  • It also helps to prevent any cracking or breaking of the glass during the bending process.
  • Heating the tubing allows for flexibility and customization in designing neon lights.

Inserting a gas

Neon lights are made by inserting a gas into glass tubing. The gas used in traditional neon lights is neon gas itself, although other gases can also be used to create different colors. This gas is then sealed inside the tubes at low pressure. When electricity is applied to the tubes, it ionizes the gas and creates a bright glow. Different gases produce different colors, allowing for a range of vibrant hues in neon signage and lighting fixtures.

Neon Gas and its Uses

Neon gas is used to create different colors in neon lights.

Creating different colors

Neon lights are known for their vibrant and eye-catching colors. While neon gas naturally produces a red glow, other substances can be used to create over 150 different colors in neon lights.

For example, green color is made by using argon gas in tubes lined with a green fluorescent coating. Additionally, a gold color can be achieved by combining different gases. This versatility allows neon lights to be used in various applications where specific colors are desired, adding to their visual appeal and artistic possibilities.

Used in neon signs

Neon gas is commonly used in neon signs, which are popular for their vibrant and eye-catching appearance. These signs are created by bending glass tubing into different shapes and designs.

The inside of the tubing is then coated with a phosphorescent substance that reacts with the neon gas to produce a colorful glow when electricity passes through it. Neon signs have been used for decades to advertise businesses or add a touch of retro charm to various settings.

Their unique and distinctive illumination makes them stand out from other forms of lighting, and they continue to be a popular choice for creating visually appealing signage.

Benefits of Using Neon Lights

– Neon lights are long lasting and durable.

– They have a low energy consumption.

– Neon lights create an aesthetic appeal with their vibrant colors and distinctive glow.

Long lasting and durable

Neon lights are known for their longevity and durability. These lights have a lifespan of up to 10-15 years, making them an excellent investment. Unlike other lighting options that may need frequent replacement, neon lights can last for years before needing any maintenance or repairs.

Additionally, the glass tubes used in neon lights are sturdy and resistant to breakage, ensuring that they can withstand various environmental conditions without easily getting damaged.

This makes neon lights a reliable choice for both indoor and outdoor applications, providing a long-lasting and durable lighting solution.

Low energy consumption

Neon lights are not only visually stunning, but they also have the added benefit of being energy-efficient. Unlike other types of lighting such as incandescent or fluorescent lights, neon lights require a relatively low amount of electricity to produce their vibrant glow.

This is because the process of creating light in a neon light involves stripping electrons from neon gas molecules, which requires less energy compared to heating up filaments or producing fluorescent emissions.

As a result, neon lights are not only aesthetically pleasing but also environmentally friendly due to their low energy consumption.

Creates an aesthetic appeal

Neon lights have become synonymous with a cool and retro aesthetic that instantly catches the eye. The vibrant colors, whether it’s the classic reddish-orange of pure neon or any of the other 150 hues, create a visually striking appeal that is hard to ignore.

These glowing tubes of light add a touch of nostalgia and personality to any space, be it in bars, shops, or even home decor. The soft yet intense glow emitted by neon lights gives off an artistic vibe and adds a unique ambiance to any setting.

Whether it’s spelling out words or creating intricate designs, neon lights are sure to make a statement and elevate the overall visual appeal of any space they illuminate.


In conclusion, while neon lights are known for their iconic reddish-orange glow, they are not solely made of neon gas. Other substances like argon and fluorescent coatings are used to create various colors.

Nonetheless, neon gas plays a crucial role in providing the initial bright glow that makes these lights so visually captivating. So next time you see a dazzling neon sign, remember that it’s not just pure neon but a combination of different gases working together to create an electrifying display.


1. Are neon lights actually made of neon gas?

While the term “neon lights” is commonly used to refer to various types of illuminated signs, not all of them are made with actual neon gas. Other noble gases, such as argon and helium, are also commonly used.

2. What are the different types of gases used in neon lights?

In addition to neon gas, other common gases used in neon lights include argon (which produces a blue or purple light), helium (which produces a bright yellow light), krypton (which produces a white or green light), and xenon (which produces a bright white light).

3. Why are different gases used in neon lights?

Different gases produce different colors when electrically charged inside glass tubes. By using varying combinations of noble gases, manufacturers can create custom colors for their illuminated signs.

4. Are there any safety precautions associated with working with neon gas?

Working with any type of gas can be potentially hazardous if proper safety measures are not followed. Neon gas itself is non-toxic and poses no significant health risks, but it is important to handle it properly and ensure proper ventilation when working with or repairing neon lighting systems.
