Technical Specifications

Transform your standard 12mm wide LED strips into professional, dotless neon fixtures with our 12x25mm Pro Side-Emitting Silicone LED Neon Flex Tube. This product is a high-quality, waterproof silicone diffuser designed for lighting designers, contractors, and DIY enthusiasts who demand a seamless, uniform light output.

A key innovation is the integrated smooth plastic sheet, which simplifies the process of threading your LED strip and reinforces the tube's structure for consistent curves. This flexible strip light neon flex tube allows you to create custom signage, architectural accents, and decorative lighting with the exact color and brightness of your chosen LED strip.

Please note, this is a diffuser tube only; the LED strip is sold separately.

Engineered for Ease of Use and Durability

  • The integrated plastic sheet not only simplifies installation but also provides structural support, ensuring clean, consistent bends without kinking.
  • The high-density silicone material provides excellent light diffusion while protecting the internal LED strip from dust, debris, and moisture when properly sealed.
  • Made from durable, UV-resistant, and flame-retardant silicone for long-lasting performance indoors and outdoors.
  • The 12x25mm profile provides a substantial, highly visible line of light suitable for commercial signage and architectural applications.
  • Can be mounted with dedicated clips, or installed into aluminum or flexible mounting profiles for professional results.

Frequently Asked Questions

Q: Does this neon tube come with an LED strip inside?

A: No, this is a silicone diffuser sleeve only. You must purchase a compatible 12mm wide LED strip separately to install inside it.

Q: What is the maximum width of an LED strip that can fit inside?

A: This neon flex tube is specifically designed for bare board LED strips with a maximum PCB width of 12mm.

Q: How do I insert my LED strip into the silicone tube?

A: The tube has an integrated plastic guide to make insertion easier. We recommend attaching a string to the end of your LED strip to help pull it through. 

Q: How flexible is this tube? Can I make sharp letters?

A: The tube is highly flexible for creating smooth curves and lettering. However, avoid bending it tighter than the specified minimum bend radius to prevent damage.

Q: Where can I cut the neon tube?

A: You can cut the silicone tube at any point with a sharp blade to achieve your desired length. The cutting interval of your final fixture will be determined by the cut marks on the LED strip you install inside.
