IP rating
Ratings · Also: Ingress protection rating, IP65, IP44
In short
A code for how well a fitting resists dust and water — critical in bathrooms and outdoors.
Notes
IP ratings look like IP44 or IP65. First digit = dust protection, second = water. Higher is more sealed.
Bathroom zones and outdoor lights/sockets need suitable IP ratings. Ask the electrician or supplier which zone your fitting sits in.
