Ceiling lights on a ceiling 2.25 m or lower over the bath

Ceiling lights on a ceiling 2.25 m or lower over the bath are in zone 1: IPX4 minimum (IPX5 where water jets are used for cleaning). Replacing a light like-for-like isn't notifiable in England or Wales; a new circuit is. 7 models meet it.

Zone 1
Zone 1 runs from the edge of the bath or shower tray up to 2.25 m, or to the fixed shower head if that is higher, and includes the space under the bath if it opens without a tool. With no tray, zone 1 reaches 1.2 m from the shower head.
