The LED Lighting IP Rating Guide shows the big difference between waterproof and water-resistant. Not certain what IP Rating you need when it comes to lighting projects? Interpreting charts and labeling can be confusing—especially between a liquid protection rating of 7 or 8.
In this article, we’ve made it easy for you to determine the level of enclosure protection you need for any lighting project.
In an environment where dust or water could damage electronic components—such as LED strip lighting—a sealed enclosure is used to prevent exposure and protect the electronics. The Ingress Protection or IP rating refers to the level of protection offered by the enclosure against both solids and liquids.
The rating consists of the letters IP followed by two digits, which indicate the degree of protection offered for both solids and liquids—according to the ANSI/IEC 60529-2020. The higher the number the better the protection.
The first digit indicates the level of protection that the enclosure provides against the ingress of solid foreign objects that could damage circuitry including tools, fingers, materials, and dust.
The second digit defines the protection of the equipment inside the enclosure against various forms of moisture (drips, sprays, submersion, etc).
Sometimes a number is replaced by X, which indicates that the enclosure is not rated for that specification.
The first digit represents the protection against solid objects (6) and the second number (7) against water. An IP67 Flexi-Tape enclosure completely prevents ingress of dust (6) and protects from immersion between 15 centimeters and 1 meter in depth. (7)—based on the reference chart below.
X – Not rated
0 – No protection/ No test required
1 – Protected against objects greater than 50mm diameter
2 – Protected against objects greater than 12.5mm diameter, such as a finger
3 – Protected against objects greater than 2.5mm
4 – Protected against objects greater than 1.0mm
5 – Protected from limited dust ingress, dust does not enter in harmful quantities to interfere with the correct operation or impair safety
6 – Total protection from dust ingress
X – Not rated
0 – No protection / No test required
1 – Protected against vertically falling drops of water
2 – Protected against vertically falling water drops when enclosure tilted up to 15°l
3 – Protected from low-pressure water spray less than 60 degrees from vertical
4 – Protected from low-pressure water splash from any direction
5 – Protected from low-pressure water jets—similar to a water hose—from any direction
6 – Protected from high-pressure water jets—similar to a fire hose—from any direction
7 – Protected from temporary immersion between 15 centimeters and 1 meter in depth for 30 minutes.
8 – Protected from continuous immersion for a specified depth and time. Conditions should be more severe than for numeral 7.
9K – Protected from steam-jet cleaning
