Neon signs can be created using glass tubes filled with gas that generates colorful illumination.

One of the main advantages of such signs is their vintage appeal. Glass neon also complements various interior styles such as loft, minimalism, pin-up, pop art, and postmodernism.

On the downside, they require high voltage (up to 9000 V), are fragile, and are not easily repairable. Careful handling is necessary with these signs, as they are prone to breakage. Additionally, in case of damage, broken glass might be a concern in indoor spaces.

This is the safest type of neon signs. Unlike glass neon, flexible neon signs use LED strings inside.

In terms of brightness, these signs surpass traditional neon signs, especially during daylight hours.

Flexible neon is safe, as the sign operates at just 12V. There is no gas or mercury inside, making it completely harmless to humans. Moreover, this type of sign suits almost any interior.
