IP (International protection) of Lights
IP degree is combination from two numerals:
First characteristic numeral - protection against the ingress of solid foreign objects
Second characteristic numeral - protection against the ingress of liquids
(More big of the numeral, the protection is more better)
First characteristic numeral - protection against the ingress of solid foreign objects
Second characteristic numeral - protection against the ingress of liquids
(More big of the numeral, the protection is more better)
