IP Ratings

• Inside the bath or shower. Any fittings used here must be SELV (maximum 12 volt) and have a minimum rating of IPX7

• Above the bath or shower to a height of 2.25m, a minimum rating of IPX4 is required.

• The area stretching to 0.6m outside the bath or shower and above the bath of shower, an IP rating of at least IPX4 is required.

• Our recommendation is to use the IP65 downlights in the bathroom area to avoid steam from your shower or bath from penetrating the light fittings.
