While PVC neon flex is often labeled as IP65, we do not recommend PVC neon light for outdoor projects. The reason why we do not recommend IP65 certified PVC neon light for outdoor projects is because that standard IP65 laboratory tests don’t simulate long-term UV exposure. PVC contains “plasticizers” that evaporate under sunlight, causing the material to shrink, yellow, and crack. Once cracks appear, the IP rating is void. For a more detailed and professional explanation, please see our previous related articles.
We recommend Integrated Silicone Advertising Neon Flex for true outdoor durability.
