What is IP Rating?

IP stands for Ingress Protection.

It is an international method used to describe the protection a device will have against solid objects and liquids.

An IP rating was comprised by 2-digit numbers, which give you information about the protection level.

  • The first number refers to the protection against solid objects – such as dust, sand, dirt, etc.
  • The second number refers to the protection against water.

For example, IP 20 (ordinary)

No. 2 = Protection against objects greater than 12mm in diameter. Eg fingers and hands.

No.0 = No protection from entry of water.

Most of our lighting fixtures are IP 20, they are designed for all indoor applications only.
