Product Information

Create stunning, perfectly uniform linear lighting with the FLNLT-BS1220-NC Black Neon LED Diffuser Tube. This flexible silicone housing is engineered to transform standard 10mm IP20 LED strips into a continuous, dot-free line of light. Its unique all-black exterior provides a sleek, modern aesthetic that blends seamlessly into architectural elements when turned off. The side-bending design allows you to trace curves and complex shapes on flat surfaces with ease, making it an ideal choice for professional architectural outlining, landscape lighting, and custom signage. The innovative triple-chamber internal structure not only ensures flawless light diffusion but also enhances the tube's flexibility and durability for both indoor and outdoor applications. 

Key Features

Seamless, Dotless Light Output

A unique triple-chamber design diffuses light from high-density LED strips, eliminating hot spots for a truly uniform, neon-like glow.

Modern All-Black Housing

The sleek black silicone body is discreet when unlit, providing a clean look that integrates perfectly with contemporary designs and dark surfaces.

Flexible Side Bending

The side-bending (horizontal) flexibility is ideal for outlining building facades, creating custom signs, and following landscape contours.

Durable & Weatherproof

Made from high-grade silicone, the tube is UV-resistant and can be sealed to an IP67 rating for reliable performance in outdoor environments, won't yellow or crack under UV exposure.

Easy LED Strip Installation

An integrated pull-string simplifies the process of feeding your 10mm LED strip through the channel, saving time and effort.

How to Install an LED Strip in This Neon Tube

  • Select a compatible IP20 LED strip with a maximum width of 10mm.
  • Securely tie the included pull-string to the end of your LED strip.
  • Gently pull the string from the opposite end of the silicone tube to guide the LED strip smoothly inside. Avoid forcing or bunching the strip.
  • For a weatherproof seal, apply silicone sealant to the end caps and press them firmly onto both ends of the tube.
  • Mount the finished neon flex assembly using mounting clips spaced appropriately to support the tube's weight and shape.
  • If you purchase both our LED strips and neon tubes, we offer a free neon light assembly service—simply leave a note in the comments section. For large quantities involving very short lengths of lighting, we will charge a customization fee.
⚠ Precautions
  • This product is a diffuser tube only; LED strip, power supply, controller, and end caps are sold separately.
  • Only use non-waterproof (IP20) LED strips. Waterproof strips with silicone coatings are too thick to fit.
  • Properly sealing the end caps with silicone adhesive is critical to achieving a high IP rating for outdoor use.
  • Do not bend the tube tighter than its specified minimum bend radius to avoid damaging the tube and the internal LED strip.
  • Power consumption and voltage drop are determined by the LED strip you install. Follow the strip's guidelines for maximum run length.

What's in the Box

  • 1 x Black Silicone Neon LED Diffuser Tube (FLNLT-BS1220-NC) at your selected length.
  • 2 x End Cap (Note: mounting clips are optional and can be sold separately.)
