Katrin ceiling light: can be used indoors and outdoors thanks to the IP44 protection rating Katrin proves itself as an optimal light source for places other than the bathroom: It is equipped with an IP44 protection rating (against spraying water) and thus can be used in other damp rooms like a staircase or cellar. The round opal glass shines bright light for a good general light, but the matte nickel edge makes Katrin a highlight in the room. The bayonet connection makes changing the bulb very easy. Bulb not included. This manufacturer, who develops and finishes design-orientated lights out of high-quality materials such as brass or blown glasses, is characterised by high vertical integration as a guarantee for the exclusive quality of their products.
