IP Value
What’s an IP value?
The IP value indicates to what extent electrical appliances such as lighting fixtures are shielded against
solid objects and water. An IP value always consists of two digits.
The first digit indicates protection against solid objects. The second number indicates the degree to
which the appliance is protected against water.
It makes sense that when a device is well sealed against water, it is also difficult for solid objects to
enter the device. A high second digit is therefore always accompanied by a high first digit.
