Real Neon vs LED Signs: Why the Difference Actually Matters

Neon is one of the most misunderstood materials in modern signage.
Today, many signs marketed as “neon” are actually plastic LED tubes designed to imitate the look—often without the depth, warmth, or longevity that made neon iconic in the first place.

This page explains the real differences between authentic glass neon and LED neon-style signs, including how they’re made, how they look, and where each one makes sense—so you can make an informed decision before buying.

What Is Real Neon?

Real neon signs are made using hand-blown glass tubing filled with noble gases. When electricity passes through the gas, the tube emits a continuous, glowing light. This is the same process used in original neon signs that lined American highways, diners, theaters, and service stations throughout the 20th century.

Each tube is bent by hand over a flame, making every real neon sign slightly unique. The result is a glow with depth and character—something that can’t be replicated with plastic materials. That's Why You Should Always Buy Real Neon.

Real neon has been used for decades because it:

  • Produces a smooth, uninterrupted glow
  • Interacts naturally with porcelain enamel and metal surfaces
  • Can last for decades when properly built and maintained

What Is LED “Neon”?

LED “neon” signs are not neon at all. They use plastic or silicone tubes with small LED diodes inside to mimic the appearance of neon.

These signs are lightweight, inexpensive to produce, and widely used in modern décor. While they can resemble neon from a distance, the light they produce is fundamentally different—individual points of light diffused through plastic rather than a continuous glow.

LED neon-style signs are typically chosen for:

  • Lower upfront cost
  • Temporary installations

Why Real Neon Looks Different

Real neon produces a living glow—the light is created within the glass itself rather than projected outward. This creates depth, warmth, and subtle variations in brightness that LED signs can’t replicate.

When paired, real neon porcelain signs, reflects and diffuses light in a way that feels dimensional rather than flat. This is why real neon photographs differently, feels heavier in person, and immediately stands out in a space.


Where LED Makes Sense

LED neon-style signs are not “bad” products—they’re simply built for different purposes. LED signs may be a practical choice for:

  • Temporary events or pop-ups
  • Budget-restricted projects
  • Lightweight wall décor
  • Situations where historical accuracy isn’t important

When Real Neon Is the Right Choice

Real neon is often the better fit when:

  • The sign is a permanent installation
  • Authenticity matters
  • The sign is a focal point of a room
  • You want the look and presence of vintage signage
  • The sign will be displayed in garages, bars, restaurants, barber shops, or showrooms

Why We Chose Real Neon

Porcelain Advertising was built by people who grew up around original signs. After years in the antique advertising and auction world, it became clear that many modern reproductions had moved away from the materials and craftsmanship that made the originals special.

In fact, after a lifetime in the antique reproduction and home decor manufacturing industry, plus 15 years as a licensed auctioneer specializing in vintage advertising signs. Once I saw The Racket In the Neon Sign Industry, I couldn't wait for someone else to do something about it. 

Rather than imitate neon with plastic, we chose to build signs using real glass neon, paired with porcelain enamel and steel, because those materials are proven to last—and proven to matter to the people who care about them.


Frequently Asked Questions

Is LED brighter than real neon?

LED signs often appear brighter in photos, but real neon produces a deeper, more natural glow that’s easier on the eyes and more visually dimensional in person.

Does real neon use more electricity?

Modern neon transformers are energy-efficient. In many cases, real neon uses comparable power to LED signs of similar size.

Can real neon be repaired?

Yes. Individual neon tubes can often be repaired or replaced, which is not typically possible with sealed LED tubing.

Why does real neon cost more?

Real neon requires skilled glass bending, heavier materials, and more labor. LED signs are mass-produced using plastic components, which lowers cost.

Is LED safer than neon?

Both can be safe when properly built. Real neon operates at low current, and modern transformers are UL-rated for indoor use.
