What does IP rating mean?

IP rating is a two-digit number used to provide an ingress protection (IP) rating to electronic products (like our light fixtures). The first digit represents protection against ingress of solid objects while the second digit represents protection against ingress of liquids (water). The larger the value of each digit, the greater the protection. For example, a product rated IP65 (like our  outdoor lights) is better protected against environmental factors than a product rated IP20 (like most of our indoor pendant lights).

IP First digit: Ingress of solid objects Second digit: Ingress of liquids
0 No protection No protection
1 Protected against solid objects over 50mm e.g. hands, large tools. Protected against vertically falling drops of water or condensation.
2 Protected against solid objects over 12.5mm e.g. hands, large tools. Protected against falling drops of water, if the case is disposed up to 15 from vertical.
3 Protected against solid objects over 2.5mm e.g. wire, small tools. Protected against sprays of water from any direction, even if the case is disposed up to 60from vertical.
4 Protected against solid objects over 1.0mm e.g. wires. Protected against splash water from any direction.
5 Limited protection against dust ingress.
(no harmful deposit)
Protected against low pressure water jets from any direction. Limited ingress permitted.
6 Totally protected against dust ingress. Protected against high pressure water jets from any direction. Limited ingress permitted.
7   Protected against short periods of immersion in water.
8   Protected against long, durable periods of immersion in water.
