Neon Lighting Explained: History, How It Works & Modern Applications
What Is Neon Lighting?
Neon lighting is one of the most recognisable forms of illuminated design, known for its saturated colour, soft glow, and strong visual impact. Commonly associated with signage and nightlife, neon is also used in interiors, branding, wayfinding, and artistic installations. This guide explains what neon lighting is, how it works, where it’s used, and how it compares to modern alternatives.
Neon lighting is one of the most recognisable forms of illuminated design, known for its saturated colour, soft glow, and strong visual impact. Although often associated with iconic signage and nightlife, neon is also used in interiors, branding, wayfinding, and artistic installations. This guide explains what neon lighting is, how it works, where it’s used, and what to consider before choosing it for a project.
What Is Neon Lighting?
Traditional neon lighting is a type of gas-discharge lighting made from sealed glass tubes filled with low-pressure gas. When a high voltage is applied, the gas becomes ionised and emits light. While the term “neon” is commonly used for many glowing tube signs, true neon gas produces a distinctive red-orange hue. Other colours are created using different gases and/or phosphor coatings inside the tube.
How Do Neon Lights Work?
A neon sign or neon light typically consists of shaped glass tubing, electrodes at each end, and a transformer that supplies high voltage. When electricity passes through the tube, the gas inside emits light. The colour depends on the gas and any internal phosphor coating, which converts ultraviolet energy into visible colours.
Neon Colours: Why Not All “Neon” Is Neon
Pure neon gas glows red-orange. To achieve other colours, makers may use different gases (such as argon mixtures) and coatings. This is why many “neon” signs in blue, green, or pink are still considered neon signage in everyday language, even though their colour isn’t produced by neon gas alone.
Craftsmanship: How Neon Signs Are Made
Traditional neon is handcrafted. Skilled makers heat glass tubes and bend them into letters, symbols, or custom shapes. Once formed, the tubes are processed, filled with gas, sealed, and tested. This craftsmanship is a major reason neon has a premium, authentic look that remains highly valued in design-led spaces.
A Brief History of Neon Lighting
Neon gas was identified in the late 19th century, and neon lamps and signage became commercially popular in the early 20th century. By the 1920s and 1930s, neon signs were transforming high streets and entertainment districts worldwide. Over decades, improvements in tube bending, gas purity, and electrode design enabled more elaborate and reliable installations, turning neon into a lasting icon of commercial identity and urban culture.
Common Uses for Neon Lighting
Neon remains popular because it combines visibility with atmosphere. It can act as both functional signage and decorative lighting, depending on scale, placement, and colour.
Shopfronts, Restaurants & Bars
Neon signage is frequently used to improve street presence, support branding, and create a memorable experience. It’s particularly effective for hospitality venues where ambience and visual identity matter.
Interiors & Feature Lighting
In interiors, neon can serve as a statement piece behind a bar, in a retail display, in a studio, or within a home entertainment space. It’s often paired with darker finishes, textured walls, or minimal décor to create a focused glow.
Art Installations & Events
Artists and event designers use neon for its emotional impact and photographic appeal. Neon typography and custom shapes are common in exhibitions, pop-ups, and experiential spaces where shareable moments matter.
Pros and Cons of Neon Lighting
Benefits
• Iconic aesthetic: A distinctive glow with strong cultural and design value.
• High visual impact: Excellent for drawing attention and defining a space.
• Custom craftsmanship: Bespoke shapes, lettering, and artistic detailing.
Drawbacks
• Fragility: Glass tubes can break if mishandled or impacted.
• Maintenance: Repairs typically require specialist support.
• Power use: Traditional neon can be less efficient than modern LED alternatives.
• Installation: Requires appropriate mounting, power components, and safe handling.
Neon vs LED Neon: What’s the Difference?
Modern LED neon (often sold as LED neon flex or LED neon ribbon) is designed to mimic the continuous glow of traditional neon using LEDs housed in a flexible diffused casing. It’s typically more energy efficient, more durable, and easier to install than glass neon. However, traditional neon remains the preferred choice for those seeking the authentic handcrafted look and character of true gas-discharge illumination.
How to Choose Neon Lighting
When selecting neon lighting, consider the environment (indoor or outdoor), desired colour and brightness, installation location, and ongoing maintenance needs. For high-traffic areas or projects prioritising efficiency and durability, LED neon-style solutions may be the better fit. For iconic branding or heritage aesthetics, traditional neon can deliver a unique, premium result.
Conclusion
Neon lighting remains a design classic: bold, atmospheric, and instantly recognisable. Whether you choose traditional neon for authenticity or a modern LED neon alternative for efficiency and resilience, the neon look continues to shape signage, interiors, and creative spaces worldwide.
