IP20? IP40? IP65? We’ve all heard of IP ratings but what warrants a product to be IP65 or IP40 rated?
Here at Northgate Lighting, we thought we’d put together a handy guide to IP ratings and what types of product relate to them.
An Ingress Protection rating (also known as IP rating) relates to the protection of the luminaire against solids and liquids.
The first digit of an IP rating i.e IP(6)5 relates to the protection from solid objects, this ranges from 0-6 with 0 meaning no protection from solids to 6, meaning totally dust tight.
The second digit IP6(5) relates to protection from water ranges from 0-9 with 0 meaning no protection and 9 meaning protection from powerful high temperature water jets.
Did you know?
An iPhone 7 is IP67 rated! As seen below this means that it’s totally dust tight and is protected against the effects of temporary water immersion.
The most common IP rating for light fittings that are intended for interior use is IP20 whereas other fixtures that are more likely to come into contact with water are normally rated IP44 or higher.
As IP ratings are tested to withstand certain environments specific to the product’s purpose, the different ratings aren’t inferior or superior to each other i.e. an IP65 rated product such as the SOLO downlight may be designed to be used in an environment where the product will come into contact with water. However a cornlamp, which is IP20 rated, is intended for use in warehouses etc therefore not coming into contact with water.
Examples of IP rated products available at Northgate Lighting include:
LED Tubes– IP40
It is vital for the luminaire’s IP rating to be suitable for its environment i.e an IP65 rated downlight would be suitable for a bathroom area, but what do the numbers mean for the level of protection?
See the table below for the most popular IP ratings, highlighting the different degrees of protection and how this relates to the digits.
