0 no protection no special protection against the outside   IP0-

1 prevent the intrusion of solid objects greater than 50mm and the human (eg palm) accidentally touching the inside of the LED lamp parts. Prevent foreign objects with larger size (diameter greater than 50mm) intrusion  IP1-


2 prevent the intrusion of solid objects greater than 12mm and a human being’s finger touching the inside of the LED lamp parts. Prevent the foreign objects with medium size (diameter greater than 12mm, a length greater than 80mm) intrusion  IP2-


3 prevent the intrusion of solid objects greater than 2.5mm or tools, wires or foreign objects in diameter and thickness greater than2.5mm prevention and contacting with the LED light and internal parts IP3-


4 prevent the intrusion of solid objects greater than 1.0mm or tools, wires or foreign objects in diameter and thickness greater than 1.0mm prevention and contacting with the LED light and internal parts IP4-


5 completely prevent intrusion of foreign objects. the amount of intrusion of dust will not affect the normal operation of the lamp despite it can not completely prevent dust intrusion  IP5-
