The IP (INGRESS PROTECTION) protection level system was drafted by the International Electrotechnical Commission. The lamps are classified according to their dust-proof and moisture-proof characteristics. The foreign objects referred to here include tools, human fingers, etc., should not touch the live parts of the lamp to avoid electric shock. The IP protection level is composed of two numbers. The first number represents the degree of protection of the lamp from dust and the intrusion of foreign objects, and the second number represents the degree of airtightness of the lamp against moisture and water intrusion. The larger the number, the higher the protection level.
