The IP protection level is composed of two numbers. The first number indicates the level of the lamp's protection against dust and foreign objects; the second number indicates the tightness of the lamp against moisture and water intrusion. The larger the number, the higher the protection level
1 Prevent the intrusion of solid objects larger than 50mm, and prevent the human body (such as the palm) from accidentally touching the parts inside the lamp. Prevent foreign objects of larger size (diameter greater than 50mm) from invading IP1X
2 Prevent the intrusion of solid objects larger than 12mm, and prevent human fingers from touching the parts inside the lamp. Prevent foreign objects of medium size (diameter greater than 12mm, length greater than 80mm) from invading IP2X
3 Prevent the intrusion of solid objects larger than 2.5mm, and prevent the intrusion of tools, wires or similar small foreign objects with a diameter or thickness greater than 2.5mm from touching the internal parts of the lamp IP3X
4 Prevent the intrusion of solid objects larger than 1.0mm, and prevent the intrusion of tools, wires or similar small foreign objects with a diameter or thickness greater than 1.0mm from touching the internal parts of the lamp IP4X
5 Dustproof, completely prevent the intrusion of foreign objects. Although the intrusion of dust cannot be completely prevented, the amount of intrusive dust will not affect the normal operation of the lamp IP5X
6 Dust tightness completely prevents the intrusion of foreign objects, and can completely prevent dust from intruding into the IP6X
