The fittings you should use in your bathroom are determined by certain areas in your bathroom that are catergorised by the amount of water they are subject to. The light fittings are given an IP rating to rule where that particular fitting can be used.  The IP stands for Ingress protection and is used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools or dirt) and moisture. Following the IP are numbers which have a specific meaning. The first number is the level of protection of enclosed equipment from things like dust or tools. The second number, indicates the protection level that the fitting is exposed from various types of moisture like drips, sprays or full submersion of water. Below is an IP rated Enclosures chart.

If the light fittFlairlight LED light Fitting ing is fully immersed like in the bath or shower then a minimum of at least IP67  must be used with a maximum of 12v as theses type of fittings are total immersion proof. Light fittings above the shower or bath to a height of 2250 mm must have an IP rating of at least IP65. The Flairlight IP65 12.4w Fixed regressed LED down light (product code- 10023.10) (left) is perfect to use above the shower or bath. This area above the shower or bath is known as zone 1 and all light fittings in this area must be spray proof.

Flairlight design mirror light Zone 2 is the area  600 mm outside of zone 1 in which an IP rating of at least IPX4 must be used when choosing a light fitting in that area. In addition, the area around the wash basin within a 600 mm radius of any tap is also considered as zone 2.

There is no special protection required for anywhere out of zones 0, 1 and 2 but, please note that if there is a likelihood of water jets being used for cleaning purposes then a minimum of IPx5 is required. We suggest that you consider a light with an IP rating of at least IP44 and so our Flairlight IP44 Wall / Ceiling Surface Mounted Luminaire (product code-  15121.40) is an ideal option for you to use in either zone 2 or 3 and is a stylish product to illuminate your Mirror.   A further product to consider over open surfaces could be the Product Code 15125.40.
