LED neon, often called faux neon or LED neon flex, is a type of solid-state illumination designed to replicate the continuous glow of traditional glass neon. It uses low-voltage light-emitting diodes encased in a flexible, translucent optical jacket. This material bends to form letters and shapes, offering an alternative to traditional gas-discharge tubes.
How LED neon is constructed
LED neon consists of tightly spaced LED strips running inside a light-diffusing polymer jacket. The tight spacing prevents visible light spots, creating a smooth line of light. Installers bend the material to match specific shapes and mount it to a substrate, which is a backing material like acrylic or aluminum. In some cases, the flex is pressed directly into channels cut by a CNC router.
Material and structural variations
- Silicone jackets: The industry standard for outdoor use due to high resistance to ultraviolet light and temperature changes.
- PVC jackets: A budget-friendly option that can turn yellow or become brittle over time when exposed to sunlight.
- Bending directions: Flex can be side-bending for flat curves and lettering, top-bending, or manufactured as full 360-degree round tubing.
- Lighting options: Available in static single colors, tunable white, color-changing RGB, or digitally addressable pixels for animated effects.
How it differs from traditional neon
- Power and safety: Traditional neon uses high-voltage transformers (2,000 to 15,000 volts) to excite gas. LED neon runs on low-voltage direct current (typically 12V or 24V), reducing fire and shock hazards.
- Energy consumption: LED systems generally use 70 to 80 percent less electrical power than traditional glass neon.
- Durability: The flexible polymer jacket eliminates the breakage risks, vacuum seal failures, and toxic materials associated with glass tubing.
What affects LED neon project costs
Several factors drive the cost of an LED neon sign. Total linear footage of the material is the primary factor. The number of individual cuts and soldered wire connections also adds labor time. Other variables include the complexity of the backing material, specific waterproofing requirements for outdoor use, and the power supplies needed. Estimators must also know how to calculate sign area accurately to price the custom cut-to-shape backer.
Sign codes change and vary by zoning district and overlay. Confirm with the authority having jurisdiction before submitting a permit.
Frequently Asked Questions
Is LED neon real neon?
No, LED neon does not contain neon gas or use glass tubes. It creates light using solid-state light-emitting diodes (LEDs). The term describes the visual effect rather than the actual technology used to produce the light.
Can LED neon be repaired if a section fails?
Yes, a failed section can usually be replaced without discarding the entire sign. Installers cut out the defective segment at designated cut points, solder a new piece of LED flex into the circuit, and reseal the ends.
How long does LED neon last outdoors?
Manufacturers typically rate the LEDs for 30,000 to 50,000 hours of use. Actual outdoor lifespan depends heavily on the jacket material. Silicone jackets withstand weather and ultraviolet light much longer than PVC jackets.
Do interior LED neon signs require permits?
Permit and electrical listing rules vary by local jurisdiction. Understanding the sign permit process means checking with the Authority Having Jurisdiction (AHJ) for your specific area. Some cities require certified shop labels even for simple interior plug-in signs.
How do shops show clients what an LED neon sign will look like?
Sign companies use sign estimating software or design tools to build visual proofs. Vuely is AI sales software for sign companies where a representative visits a site, captures a survey with photos, and generates a photo-accurate mockup of the sign on the customer's building.
