The IP (Ingress Protection) rating system is an international standard used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (like dust) and moisture. The first digit represents the level of dust protection, while the second digit indicates the level of water protection. So, what do the 6 and 8 in IP68 mean?

IP68 is a combination of two ratings: IP6 and IPX8. IP6 indicates the highest level of dust protection, meaning the product is completely dust-tight. This ensures that your solar lights won't be affected by dust, making them ideal for outdoor use, even in harsh environments.

Solar lights with IP68 rating are completely dust-tight, providing the highest level of dust protection. This means they can be used in areas with high dust concentration without any worries about dust ingress causing damage or affecting performance.

Examples of environments where IP6 dust protection is beneficial include construction sites, desert areas, or industrial settings with high dust levels.

IPX8: Water Protection

The X in IPX8 indicates that the product has not been tested for solid particle protection, but it has been tested for water ingress. The '8' in IPX8 signifies that the product can withstand continuous immersion in water up to a certain depth, typically 3 meters, for a specified time, usually 30 minutes.

In the context of solar lights, IPX8 means that the light can be fully submerged in water and still function perfectly, making them suitable for underwater use or areas prone to flooding.
