Break Resistant Flex Tape Light Diffuser
Super Lighting LED Innovative NeonFlex BendPro Anti-Breakage Series Silicone Flexible LED Strip Diffusers
Super Lighting LED innovates the break resistant flex tape light diffusers based on the traditional silicone led diffuser strips, which perfectly combines the flexibility of the led strip diffuser tape and the PCB protection need through the built-in plastic anti-breakage sheet inside the silicone tube.
The breakage-proof sheet is seamlessly integrated into the silicone tubing in a one-piece design, ensuring no compromise to sealing (IP67 / IP68 waterproof rating), flexibility, and light diffusion effect. And it is embedded along the backside of the led strip inside the diffuser sleeve. When bending the neon led tape, it evenly distributes stress across the PCB, preventing localized folding that could cause copper trace fractures or solder joint failure.
✓ Engineering Durability: Reduce the damage to the led strip light from repeated bending, especially suitable for neon effect projects that require frequent modeling.
✓ Safeguard: Fracture-Resistant tabs provide physical limitations to prevent users from accidentally bending the strip beyond its tolerance angle.
✓ Installation Friendly: DIY users can also bend the led neon tape light safely, reducing the risk of breakage and after-sales costs.

Does your neon light strip often get damaged?
Our 2025 new series—anti-break neon tubes—builds on the standard neon tape light diffuser design with a significant improvement. We’ve integrated a smooth plastic strip at the point of contact with the back of the led light strip. This design feature serves multiple purposes:
►Reduced Insertion Resistance: makes the led neon installation process easier;
►Force Distribution: When bending the flexible led tube neon, the plastic strip helps distribute the pressure more evenly across the PCB, prevents concentrated stress points that could otherwise lead to cracks or breaks in the PCB.
