A higher protection rating is generally recommended for outdoor lights. This is because they are exposed to different weather conditions and should therefore be particularly protected against external influences and moisture, depending on where they are used. The following applies: the more unprotected your outdoor ceiling light is installed, the higher the IP protection rating of the product should be.
You benefit from a high level of protection against contact, foreign bodies and water with luminaires with an IP65 protection rating. This means that the ceiling light is dustproof and protected against water jets. In most cases, however, IP44 protection is sufficient. Lights with this labelling are splash-proof.
