When we are choosing LED lights, we will consider the appearance, parameters, and actual working conditions of the products. Looking at the parameters, you will find there is an IP rating. Take our LED Flood light KUH Series for instance,the parameter of this lamp is IP69. Then what’s the meaning for IP rating?

IP is Ingress Protection,which is an international numeric classification to indicate the degrees of protection provided by enclosures for electrical equipment against environmental conditions. It provides a means of specifying the capacity of an enclosue to protect its contents from external solids and liquids in accordance with IEC 60598-1:2003.

IP rating consists of two numbers. The first number represents the degree of dust protection. The second number indicates the degree of water resistance. The higher the number, the higher the protection level.

The first number (0-6)— Dust level.

The following is the meaning of the number:

0 : No protection, no special protection.

1 : Objects larger than 50 mm are prevented from entering. Preventing accidental contact with the inside of the light.

2 : Objects larger than 12 mm are prevented from entering. Preventing the finger from touching the inside of the light.

3 : To prevent objects larger than 2.5mm from entering.

4 : To prevent intrusion of objects exceeding 1.0 mm.

5 : Dust prevention cannot completely prevent from entering, but the amount of dust entering does not affect the normal operation of the electrical system.

6 : Prevents dust from entering.

The second number: 0-9(K), Waterproof level, please see the details as below:

0 : No protection, no special protection.

1: Protection against vertically falling droplets, such as condensation. Ensuring that no damage or interrupted functioning of components will be incurred when an item is upright.

2: Protection against water droplets deflected up to 15° from vertical

3 : Protected against spray up to 60° from vertical.

4: Protected against water splashes from all directions. Tested for a minimum of 10 minutes with an oscillating spray (limited ingress permitted with no harmful effects).

5: Protection against low-pressure jets (6.3 mm) of directed water from any angle (limited ingress permitted with no harmful effects).

6: Protection against direct high pressure jets.

7: Protection against full immersion for up to 30 minutes at depths between 15 cm and 1 metre (limited ingress permitted with no harmful effects).

8: Protection against extended immersion under higher pressure (i.e. greater depths). Precise parameters of this test will be set and advertised by the manufacturer and may include additional factors such as temperature fluctuations and flow rates, depending on equipment type.

9(K): Protection against high-pressure, high-temperature jet sprays, wash-downs or steam-cleaning procedures – this rating is most often seen in specific road vehicle applications (standard ISO 20653:2013 Road Vehicles – Degrees of protection).
