When to make their purchase of Bathroom Lighting and bathroom lights should I consider in choosing a lamp with sufficient high-class seal. In short, the higher IP rating the thicker and more secure is the lamp.
IP65 - Just above the shower and tub. IP44 - at least. 0.6 m from duschuvud.
IP21 - 0,6 m outside the bath or shower.
Keep in mind that it is always the electrician who takes responsibility for installation, therefore belongs with your electrician what IP rating you need.
