There are a number of things to consider when purchasing and installing outdoor lights for your patio or garden, but the aspect that may be confusing for many people is the IP rating.

What is an IP rating?

An IP rating (Ingress Protection rating) is an international standard that defines a light’s suitability for different environments and weather conditions.

Most lights come with a specific IP rating made up of two digits. The first digit refers to protection against solid objects, while the second digit refers to protection against moisture. The chart below lists the specifics for each digit, but some of the more common IP ratings you will find are:

IP20 – standard for indoor use

IP23 – rain proof

IP44 – splash proof (standard for outdoor lighting)

IP55 – jet proof, dust proof

How do you know which IP rating is right for you?

Your electrician is the best person to be able to advise you as to the level of protection you need and what type of lighting can be used on verandas and under protected areas with no direct rain can access.
