Behind the Glow: Exploring the Materials Used in LED Neon Sign Making


Neon signs have been used to catch people’s attention since the 1920s, and now they are experiencing a resurgence thanks to a new generation of materials that make this form of signage much more economical.  The material used in making neon signs determines its color, brightness and thickness — thus determining how much it costs.

LED Flex Lights

LED flex lights are a very efficient means of lighting. Since they do not get hot, they are also safe to use. They are maintenance free; no expensive bulb replacements. They offer a wider spectrum of lighting which helps your plants grow faster and better than those in the natural light. LED lighting is a good option especially if you have limited space or budget. It is also energy efficient since it uses less energy and is more reliable. LEDs are long lasting.



A form of plastic called silicone can be used to create LED neon signage. Due to its extreme flexibility, the sign can be bent and curved in a variety of ways. The low resistance of silicone also enables it to withstand high-voltage currents without overheating.

Because of its elasticity, silicone is excellent for molding into curves and other shapes. Silicone is perfect for designing signs with forms that change direction or have several bends since it can maintain its shape even after being bent or twisted.



Acrylic is a strong, flexible plastic that can be used for LED neon sign making. Because of its toughness and light weight, it is frequently used. It is perfect for making custom forms and designs because it can be bent, drilled, and cut without breaking. High gloss coating on acrylic further enhances its aesthetic appeal.



The transformer is a tool used to modify electrical voltage.  The lower voltage makes sure that the sign’s interior parts don’t overheat or burn out.


Techniques Used in LED Neon Sign Making

CNC Machining

A sign’s base is frequently made from raw materials using the CNC machining method. To do this, the design’s letters, numerals, and other symbols. Furthermore, holes for lights and other elements as well as curves that give signs depth and dimension can be cut out using the CNC machine.


Laser cutting is a technique used to slice through materials such as wood, metal, and plastic.It slices through the material with a strong laser, producing incredibly exact cuts. Other names for the procedure include “laser engraving” and “laser etching.”

As a result, you may produce complex patterns and designs that are impossible to make with other techniques, such saws or drills.


UV printing is a technique used in creating LED neon signs. It involves printing with UV-sensitive ink onto a photosensitive material. The printed image is then exposed to ultraviolet light, which causes the ink to cure and adhere to the sign’s surface.

Factors to Consider When Choosing LED Neon Sign Materials

Purpose and Location

Making sure the sign is made of a material that is weather-resistant and strong enough to endure exposure to wind, water, and other elements is important if you plan to put it outside.

In order to prevent fumes from accumulating while the neon sign is on, it must be placed in a location with sufficient ventilation if it will be indoors. This can restrict where you can place your sign if you want it to be close to a window or another source of natural light.


The first factor to take into account when selecting an LED neon sign is your budget. When making a purchase, it’s crucial to know how much you can afford given the variety of possibilities on the market. The size, level of craftsmanship, and design all affect the sign’s price. Before making a purchase, you should also think about how long you want your sign to last. It will cost more than other types of signs if you want your sign to be strong and long-lasting.

Design & Customization

Consider the materials that most closely resemble the design and aesthetic of your company when creating your sign. After deciding on the design you desire, you may then select the materials that will work best with that design.

Durability & Maintenance

If a material is not durable, it may break or become damaged in some way, which can lead to your neon sign breaking down and no longer functioning. Durability is measured by how long something is expected to last before breaking down.
