Understanding IP Ratings for Lighting: A Simple Guide
What IP Ratings Mean and How to Choose the Right Protection Level
IP ratings (Ingress Protection ratings) are used to describe how well an electrical product is protected against dust, dirt and water. They are especially important when choosing lighting for bathrooms, gardens and outdoor areas where fixtures face moisture, weather or splashes. This guide explains what each number means and how to choose the right IP rating for your space.
An IP rating contains two digits:
First Digit: Protection Against Solids
This number ranges from 0–6. Higher numbers mean better protection against dust and foreign objects.
Second Digit: Protection Against Water
This number ranges from 0–8. Higher numbers indicate better protection against moisture and water.
IP Ratings for Bathroom Lighting
Bathrooms contain moisture, steam and splashes, so lighting must meet the correct safety zones.
