If you are looking to use downlights in a bathroom, the IP rating is extremely important. IP44 is suitable for bathroom zones 2&3 and IP65 can be used in zones 1,2 & 3.
IP rating is short for Ingress Protection. This is usually a two-digit grading system that’s applied to the enclosure of a mechanical or electrical item. The IP rating gives customers an indication of the item’s resistance to various types of unwanted intrusion. In home use, this tends to be useful for lighting, as it shows us which fittings are suitable for bathroom use.
