The type of protection ensures the operational safety of luminaires. The IP code (Ingress Protection) is shown with two code numbers. The first code number (1 to 6) describes the scope of protection against the ingress of foreign bodies, the second code number (1 to 8) provides information on the degree of moisture protection. The higher degree of protection correspondingly includes the lower. If one of the two protection type code numbers is not shown, it will instead have a big 'X' for 'untested'.
