What is the meaning of lamp protection grade IP65?
Answer: Dustproof grade (the first "I" indicates)
0: no protection
1: prevent large solid invasion
2: prevent medium size solid invasion
3: prevent small solids from entering and invading
4: prevent solid objects larger than 1mm from entering
5: prevent harmful dust accumulation
6: completely prevent dust from entering
Waterproof grade (indicated by the second P)
0: no protection
1: Water drops into the shell have no impact
2: When the shell is tilted to 15 degrees, water drops into the shell have no impact
3: water or rain from the corner of 60 degrees to the shell has no impact
4: The liquid poured into the shell from any direction has no harmful effect
5: Rinse with water without any harm
6: can be used in the cabin environment
7: water resistance in a short time (1m)
8: soaking water for a long time under a certain pressure
So IP65 means that the lamps are completely protected from dust, and there is no harm when washed with water.
