1 What is an IP44 rating and what rating do my lights need to have in my desired location?

The IP code is an International Protection marking which indicates a standard of protection against particle ingress, amongst other factors. An IP44 marking specifically indicates protection from the intrusion of particles. Lights which are IP44 rated are designed for use in bathrooms and other environments where water spray is a risk factor. Not all bathroom lights are at risk of water intrusion and therefore may not need to be IP44 rated.
For the purposes of installing electrical equipment, a bathroom is divided into zones.

The criteria for each zone is based on the risk of electric shock. The zones relate to the IP rating of products and where they can be safely installed.
