What does the waterproof grade number of LED light strip mean

LED lights come with a waterproof and dustproof rating, and IP68 waterproof LED light strips are often heard. So what does IP68 mean?

LED light strips are distinguished by their waterproof grade based on the material they are made of.


XX is a two digit number;

The first digit represents the level of protection against solids, with 7 levels, and 0-6 represents each level.

The second digit represents the level of protection against liquids, with 9 levels, with 0-8 representing each level.

Dust level:

0: No protection

1: Prevent large solid intrusion

2: Preventing intrusion of medium sized solids

3: Prevent small solid intrusion

4: Prevent solid objects larger than 1mm from entering

5: Prevent harmful dust accumulation

6: Completely prevent dust from entering

Waterproof grade

1: Water droplets dripping into the shell have no effect

2: When the shell is tilted to 15 degrees, water droplets drop into the shell without affecting it

3: No impact of water or rainwater from a 60 degree corner to the shell

4: The liquid splashed onto the shell from any direction has no harmful effect

There are four common waterproof levels of LED light strips: IP20, IP65, IP67, and IP68
