The English abbreviation of the protection level of LED waterproof Power Supply is IP (Ingress Protection rating). It is drafted by IEC (International Electro Technical Commission) to classify the characteristics of dust-proof, prevent foreign objects, waterproof, and moisture. The IP** that we usually see on lamps and Power Supplies is what we call the degree of protection, such as IP45, IP65, IP68, I think everyone has seen it, but IP45, IP65, IP68, what do they represent? What does it mean, what kind of protection level does it belong to?


The IP protection level is composed of two numbers:


1. The first number indicates the product's level of dustproof and foreign object intrusion;

2. The second number indicates the degree of airtightness of the product against moisture and water intrusion. The larger the number, the higher the protection level.


The meaning of the first number :


"0" means no protection , no special protection for people or things outside.

"1" means to prevent the intrusion of solid objects larger than 50mm , and prevent the human body (such as the palm) from accidentally contacting internal parts. Prevent foreign objects of larger size (diameter greater than 50mm) from intruding.

"2" means to prevent the intrusion of solid objects larger than 12mm , and to prevent human fingers from contacting internal parts. Prevent foreign objects of medium size (diameter greater than 12mm, length greater than 80mm) from intruding.

"3" means to prevent the intrusion of solid objects larger than 2.5mm , and to prevent the intrusion of tool wires or similar small foreign objects with a diameter or thickness of more than 2.5mm to reach internal parts.

"4" means to prevent the intrusion of solid objects larger than 1.0mm , and prevent tools, wires or similar small foreign objects with a diameter or thickness larger than 1.0mm from intruding and contacting internal parts.

"5" means dustproof, completely preventing foreign objects from intruding. Although it cannot completely prevent the intrusion of dust, the amount of dust invaded will not affect the normal operation.

"6" Dust tight Completely prevent the intrusion of foreign objects, and can completely prevent the intrusion of dust.


The meaning of the second number:

"1" means to prevent the intrusion of dripping water, and vertical dripping water droplets (such as condensed water) will not cause harmful effects.

"2" means that dripping can still be prevented when tilted at 15°, when the product is tilted from vertical to 15°, dripping will not cause harmful effects on the lamp.

"3" means to prevent the intrusion of sprayed water, rainproof or prevent the water sprayed from the direction where the angle between the upper and the vertical is less than 60°into the product and cause damage.

"4" means to prevent splashing water from intruding and preventing water splashing from all directions from entering the product and causing damage.

"6" means to prevent the intrusion of big waves, and the products installed on the deck can prevent damage caused by flooding due to the invasion of big waves.

"7" means to prevent water intrusion during immersion. The product can be immersed in water for a certain period of time or the water pressure is below a certain standard to ensure that no damage is caused by water ingress.

"8" means to prevent water intrusion during sinking. The product will sink indefinitely before the specified water pressure to ensure that it will not be damaged due to water ingress.


Generally speaking, LED waterproof power supply generally requires IP65 / IP67. Of course, it also depends on the application. The IP65 waterproof rating can meet the needs for LED street lights and indoor bathroom LED lighting. If it is a navigation light for going to sea, only the IP68 rating can be used.
