Depending on the conditions in the facility, warehouse lighting should have an appropriate degree of resistance to impacts, dust and water. The models have the described IP water resistance class and IK resistance class.
How to read these markings correctly?
The IP class has two digits. The first is on a scale from 0 to 6, the second from 0 to 8. For example, if the luminaire is IP68 rated, it is (6) completely dustproof and (8) protected even when submerged in water. So the higher the score, the better.
The same applies to resilience IK. The scale is counted from 0 to 10. The IK10 symbol means that the luminaire will withstand an impact of 20J, i.e. a hit with a heavy hammer from a distance of 40 cm .
