The differences between commonly sold IP65, IP67, & IP68 strips are slight, but very important. Using the below chart as a guide, we can see that all strips are protected at the highest level from solids and dust. The variations come with the protection against liquids.
IP20 : non-waterproof. barely PCB.
IP65 : Water resistant. “Protected against water jets from any angle” *Do NOT submerge IP65 LED lights, these are not waterproof.
IP67 : Water resistant plus. “Protected against the events of temporary submersion (10 minutes)”*Do NOT submerge IP67 LED lights for extended periods, these are not waterproof.
IP68: Waterproof “Protected against the events of permanent submersion up to 3 meters”
