The IP code in the outdoor area
A lamp that is used outdoors must withstand wind and weather. This results – similar to the bathroom, depending on the place of use and purpose certain requirements, especially on dust and water protection. Below we have shown typical locations for outdoor lighting and their minimum requirement for the respective IP protection.
Code IP 23
When installed directly under a roof, the lamps must have at least protection class IP23. Thus these lamps are protected against foreign objects with < 12.5 mm diameter and dripping water (15% incline impact).
Code IP 44
If the lights are installed on a covered wall, they must have at least IP44. Lamps with IP44 are protected against solid foreign objects of 1 mm diameter and splash water. That is, water that splashes against the housing from any direction must not have a damaging effect on the lamp.
Code IP 65
If you want to install lamps on or in the ground, under a roof or overhead, you have to use lighting with IP65. These lamps are then dustproof and protected against water jets. This means that the lamps remain safe even when they are subjected to heavy rain or when sprayed with a garden hose.
Code IP 67
Lights that are placed outside in the ground or road must at least comply with IP67. These lamps could then also endure temporary submergence in water without damage.
Code IP 68
Lamps for a pond or a stream course have to comply with IP68 as they are permanently under water. IP68 is therefore also the highest protection class for lamps.
Due to the dangerous combination of water and electricity in wet rooms and outdoor areas, these lights should only be installed by a licensed electrician. However, architects and light planners are also happy to help with a well thought-out planning.
