In this article, we’ll explore why more and more buyers and project engineers are choosing IP67 neon flex for outdoor facade lighting—and how to select the right product from a reliable manufacturer.

What is IP67 Waterproof Flexible Neon Flex?

Flexible neon flex is a modern LED lighting solution that mimics the visual effect of traditional glass neon but with advanced features such as high flexibility, energy efficiency, and durability. It is constructed with high-grade silicone or PVC materials that allow the strip to bend freely, making it ideal for outlining complex architectural shapes and curved surfaces.

The IP67 rating indicates that the product is fully protected against dust ingress and can withstand temporary immersion in water up to 1 meter deep for 30 minutes. This level of waterproofing makes IP67 neon flex a reliable option for outdoor installations, even in challenging environments such as rain, snow, or coastal humidity.

Unlike standard LED strips that may expose the diode or circuit to weathering, neon flex features a fully sealed body that delivers uniform, dot-free illumination. It not only provides a continuous light output but also enhances safety and durability in outdoor applications.

Key technical features typically include:

High flexibility for easy shaping around facades and signage

UV-resistant outer layer to prevent yellowing or cracking

Wide input voltage options (e.g., 12V/24V) for various project requirements

Multiple color options, including single-color, RGB, and RGBW

IP67 waterproof flexible neon flex is not just a lighting product—it is a reliable, low-maintenance solution for long-term outdoor architectural lighting.

Advantages of Using IP67 Neon Flex for Outdoor Facade Lighting

When it comes to outdoor architectural lighting, durability and performance are key. IP67 waterproof flexible neon flex offers a range of advantages that make it an ideal solution for façade lighting in commercial, industrial, and public space projects. Below are the key benefits that set it apart:

Outdoor exposure often leads to material degradation over time. Neon flex uses UV-stabilized materials (such as silicone) to prevent yellowing or cracking, ensuring the product retains its clean look and performance over years of exposure.

6. Energy Efficient and Cost-Effective

LED neon flex consumes far less energy compared to traditional neon glass tubing, offering lower operational costs. Its long lifespan (often 30,000–50,000+ hours) reduces maintenance frequency, saving time and money for commercial and municipal clients.

7. Easy Installation with Complete Accessories

IP67 neon flex is typically available with a full range of mounting clips, aluminum profiles, end caps, connectors, and power supplies—simplifying the installation process for contractors and integrators.

This combination of reliability, aesthetics, and installation ease makes IP67 neon flex a smart choice for professionals working on outdoor lighting projects.

Applications of Waterproof Neon Flex in Outdoor Projects

Thanks to its flexibility, durability, and seamless glowing effect, IP67-rated flexible neon flex has become a preferred lighting solution in a wide range of outdoor applications. From building facades to public infrastructure and signage, it offers both functional and aesthetic value in demanding environments. Here are three key application scenarios where waterproof neon flex truly shines:

1. Architectural Facade Outline Lighting

On modern buildings, facade lighting is more than illumination—it’s identity. Neon flex brings architecture to life at night, tracing clean lines, corners, and curves with a smooth, uninterrupted glow. For vertical surface installations, especially on high-rise buildings or complex structural designs, flexible neon creates a striking visual impact that enhances the entire skyline.

With RGB digital capabilities, it can display dynamic, flowing effects that turn static structures into vibrant city landmarks. Our NAA2020TC model, designed for vertical bending and chasing RGB effects, is ideal for this purpose—bringing creativity and performance to architectural lighting professionals.

2. Bridge and Landscape Accent Lighting

In bridges, parks, and garden landscapes, lighting must be both decorative and weather-resistant. Neon flex adds atmosphere and safety to these spaces, outlining paths, railings, or water features with soft yet vivid lines of light. RGB color-changing modes help create seasonal themes or interactive effects, transforming public areas into memorable experiences.

Our NAQ1616TC, with vertical bending and RGB color change, blends beautifully into structural elements while delivering reliable lighting performance under all weather conditions.

3. Signage and Logo Outlining

In commercial settings, clear and attractive signage is essential for brand visibility. Neon flex is the ideal solution for outlining letters, logos, and symbols—especially where traditional rigid lighting can’t adapt to intricate shapes. Its flexibility, uniform brightness, and clean edge glow help logos stand out both day and night.

For these applications, our NQX0612SC—a horizontal bending model with crisp white or single-color output—is a perfect match. Slim, subtle, and easy to integrate, it’s designed to bring brand identities to light.

IP67 vs IP65 vs IP68 – Which is Best for Outdoor Facade?

When selecting flexible neon lighting for outdoor projects, waterproof performance is a critical consideration. IP65, IP67, and IP68 are the most common protection ratings available on the market—but which one offers the right balance between reliability and cost for facade lighting?

Let’s break down the differences across three key areas:

1. Protection Level

IP65 provides basic protection against dust and water spray. It is splash-resistant, but not suitable for heavy rain or immersion. It can be used in covered outdoor areas but may fail under prolonged exposure to harsh weather.

IP67 offers full dust protection and can withstand temporary immersion in water (up to 1 meter for 30 minutes). This makes it highly reliable for outdoor facades exposed to rain, snow, or humidity. For most architectural applications, IP67 is the practical sweet spot.

IP68 takes it a step further, supporting long-term underwater use. While this level is necessary for underwater lighting (e.g., pools or fountains), it’s usually over-specified for facade lighting—and comes with a significant cost increase.

2. Cost Difference (Driven by Manufacturing Process)

The price difference between these protection levels isn’t arbitrary—it’s based on how the product is made:

IP65 neon flex typically uses basic silicone sleeves or partial glue-filling, requiring less material and simpler production, resulting in a lower unit cost.

IP67 neon flex involves full silicone extrusion or solid glue-filling, ensuring total sealing of the LED components. This process requires more precise tooling, better quality control, and more raw material, which moderately increases the cost but significantly improves durability.

IP68 neon flex requires completely encapsulated structures, multi-layer sealing, and often custom molds. The complexity of ensuring long-term water resistance under pressure means higher reject rates and higher production costs—often 30–50% more than IP67.

3. Application Suitability

Protection Level	Best Used In	Limitations
IP65	Covered outdoor areas, signage under eaves	Not suitable for direct rain or immersion
IP67	Facade outlines, bridges, landscape edges	Not for permanent underwater installations
IP68	Pools, fountains, underwater architecture	Overkill (and overpriced) for facades

Conclusion: IP67 is the Ideal Choice for Outdoor Facade Projects

For most distributors, lighting contractors, and project integrators, IP67 waterproof neon flex strikes the right balance: it delivers robust protection against the elements, fits a wide range of outdoor applications, and keeps the cost within a reasonable range.

Why Choose Flexible Neon Over Traditional Glass Neon

Compared to traditional glass neon lights, flexible neon offers significant advantages in terms of safety, efficiency, and versatility—especially for outdoor projects and modern architectural designs.

Safer to Install and Operate

Glass neon tubes are fragile, require high-voltage transformers, and pose risk during transport and installation. In contrast, flexible neon is made from durable silicone or PVC and operates on safe low-voltage (12V/24V DC) systems—much safer for both workers and public areas.

Easier Shaping and Mounting

Flexible neon can be bent and cut to follow curves, corners, and complex designs without custom glasswork. This allows for faster on-site installation and creative freedom in building outlines, logos, and landscaping.

Energy Efficient and Long-Lasting

LED neon uses far less power than glass neon and offers up to 50,000 hours of lifespan, reducing both energy costs and maintenance frequency—important for long-term outdoor applications.

Weatherproof and Durable

With IP67 or higher ratings, flexible neon is fully sealed against moisture and dust, unlike traditional glass neon which is not weather-resistant without added protection.

In short, flexible neon is a modern, practical alternative for lighting designers, installers, and distributors looking for reliable, low-maintenance, and visually appealing solutions.

How to Choose the Right Neon Flex from a Reliable Manufacturer

Choosing the right neon flex goes beyond just color and size—quality, reliability, and support are just as important, especially for large-scale or long-term projects.

Here are a few key factors to consider:
