Black Silicone Neon Flex Diffuser For LED Strips (20x20mm) 5 MTR Roll

This silicone LED diffuser is a 20x20mm flexible black neon-style profile designed for recessed and surface-flush installations. Supplied on a 5 metre roll, this flexible silicone LED diffuser provides a clean, continuous lighting effect when used with LED strip lighting systems. 

The profile is engineered to sit flush within routed channels, creating a seamless architectural finish. It is compatible with LED strips up to 14mm wide, making it ideal for COB LED applications where smooth, dot-free illumination is required. 

The black silicone body conceals the LED strip when off and produces a controlled, modern glow when illuminated, making this black silicone LED diffuser ideal for design-led lighting installations. 

The black silicone LED diffuser uses an opal silicone inner layer to soften and evenly distribute light, eliminating visible hot spots and producing a uniform neon-style glow. 

Key features include: 

This LED silicone diffuser is ideal for architectural and decorative lighting applications where a seamless finish is required, including: 

The profile delivers a premium “neon effect” finish with the diffuser sitting level with the surrounding surface. 

Installation of this flexible silicone LED diffuser is straightforward: 

For LED strips exceeding 10W per metre, installation alongside an aluminium heat-sink profile is recommended to ensure effective thermal management and maximise LED lifespan. 

For curved installations (left and right bends), a suitable bendable LED strip such as a side-bending COB or flexible strip is recommended to maintain consistent illumination.
