A range of bathroom lighting including Zone 1, 2 & 3 lights rated for use in different areas of thebathroom. Zone 1 is for use inside a shower cubicle and around a bath and has a minimum IP rating of IP65, Zone 2 is for use on the wall up to a height of 2.25m, again having a minimum IP rating of IP44. Zone 3 can have any light in it, it does not have to be an IP rated bathroom light.
Zone 0 is inside the bath or shower itself. Any fitting used in this zone must be low voltage, (max 12v) and be rated at least IP67 which is total immersion proof.
Zone 1 is the area above the bath or shower to a height of 2.25m from the floor. In this zone a minimum rating of IP45 is required but it is generally accepted that IP65 is to be used. It's also worth noting that most shower lights are rated at IP65 in any case.
Zone 2 is an area stretching 0.6m outside the perimeter of the bath and to a height of 2.25m from the floor. In this zone an IP rating of at least IP44 is required. In addition it is good practice to consider the area around a wash basin, within a 60cm radius of any tap to be considered as zone 2.
Outside Zones are anywhere outside zones 0,1 and 2 (subject to specific limits) and where no water jet is likely to be used. There are no special IP requirements in this zone, however we suggest that you consider a light with an IP rating of at least IP20+.
