The reasons why does IP65 certified PVC neon light get water inside are:
- Because an IP65 rating is a “Time Zero” laboratory test. It only proves the product can withstand water jets for about 3 minutes when it’s brand new.
- In the real world, factors like Thermal Expansion, UV Aging, and Plasticizer Migration create micro-cracks over 6-18 months, which the initial lab test does not account for.
Our Recommendation: To ensure long-term outdoor reliability, we strongly suggest using Genuine Silicone Neon Lights. For advertising signage, we recommend our 6*12mm Silicone Neon Flex with a 1cm cutting length. This product is not only built for extreme weather but also perfectly aligns with CNC engraving software (such as Artcut or Aspire). The 1cm minimum drawing unit allows for precise matching with your design, ensuring seamless connections with No Dark Zones. For more details, please explore our related technical guides.
