What Is Waterproof IP Rating?

Lighting are divided into indoor lighting and outdoor lighting. As an outdoor light, it needs many other functions, such as waterproof. Whenever it rains, outdoor lights can still be used normally, which should be IP65 or IP67 waterproofing.

Now, let’s take a look at the waterproof IP rating of outdoor lighting.

1. Outdoor waterproofing grade and its significance

Outdoor waterproofing grade refers to the waterproof performance index of a certain waterproof material or product. It is a standard set by international, national or regional standards to measure the waterproof performance of materials.

Specifically, the waterproof level is divided into four levels, expressed in the form of IPXX, where X represents a number, respectively indicating the standard of the level.

The first X indicates the dustproof level, and the second X indicates the waterproof level.

1. IPX0: No rating

2. IPX1: Water droplets falling vertically

3. IPX2: Water droplets falling upward at a 15-degree angle

4. IPX3: Water droplets falling upward at a 60-degree angle

5. IPX4: Water spray from all directions

6. IPX5: Water droplets from any direction Low pressure water spray

7. IPX6: High pressure water spray from any direction

8. IPX7: Limited water immersion

9. IPX8: Prolonged immersion

2. What Is The Difference Of IP65 To IP68 waterproof Rating?

 

As you can see from the table below(waterproof level description), the waterproofing of IP65 and IP66 belongs to the same protection level, both of which are pressurized water shower; IPX7 and IPX8 are waterproofed, and the level is relatively extended by one level.

Although IP67 and IP68 belong to the same level, from the definition and test method (refer to the figure below: waterproof level test method), we can easily find that there are quantified standards from IP Rating 5 to 7, and only 8 is not quantified.

From a broad understanding, the waterproof requirement of IP68 is a dynamic value, and the waterproof level requirements can be agreed upon by both parties through negotiation, but the overall requirement is to be more stringent than IP67.

And, many people will ask, what is products marked IP68? If there is no standard, how does the IP68 test report come from?

This is a good question. Although IP68 is a dynamic value, it also has interval standards. Interval values are usually obtained using deep-water testing machines in the range of 1 meter to 50 meters. In recent years, some diving equipment has increased this value to 500 meters. Of course, most products have been used at depths greater than 50 meters. It loses its reference value. As for the required meter of water depth in the middle, it depends on the agreement between the two parties.

 

 

3. How to choose outdoor waterproofing grade?

 

The choice of waterproof grade for outdoor lighting should be based on actual conditions. If short-term, light rain protection is required, a waterproof rating of IPX1-IPX4 is sufficient. But if you need to work in harsh weather environments, such as outdoor street lights, floodlights, landscape lighting, etc., you need to consider water immersion, so you need high waterproof levels IPX7 and IPX8 grade.

For example, the LED driver IP65 means that the LED driver can completely prevent the intrusion of dust and prevent water from flying from the nozzle from all directions from intruding into the LED driver and causing damage. At present, most of the LED drivers produced by our company adopt IP65 protection level. With the continuous development of science and technology, the environment has also encountered great damage, and the application environment has become very complex. The LED driver IP65 is no longer sufficient, so we also have led driver IP66 and led driver IP67.

IP65 waterproof application :

Outdoor lighting direction down, tilt Angle does not exceed 15° independent lighting application, IP65 can be selected, of course, here requires IP65 lamps do not have a structural combination surface in the top elevation Angle of 15°, if it exists, it requires IP66 grade. Street lampsled high bay lights, floodlights, etc., can be identified as this application scenario, and these lamps are often large in power, IP65 grades are more conducive to the heat conduction and heat dissipation of lamps.

IP66 waterproof application :

Outdoor lighting direction upward, or tilt Angle more than 15° independent lamps or single-sided secondary contact application scenarios, must use IP66 waterproof grade lamps. Most landscape lighting applications, such as buildings, Bridges and trees, can be classified as such, such as wall wash lights on building facades, line lights or point lights.

IP67 waterproof application :

IP67 waterproof lamps are recommended for outdoor water-flooded ground buildings and waterfront buildings with gaps below 1 meter and embedded building facades. Such as the ground flower beds, walking paths, stairs, waterfront wall washing, casting light and railings, line lights and point light sources embedded in the building, etc., can be classified here. Special ground buildings with more than 1 meter gap flooding should negotiate IP68 waterproof grade lamps. When choosing IP67 or IP68 grade lamps, we must pay special attention to the thermal conductivity and heat dissipation performance of lamps, which is often easy to do at the waterproof level, and the thermal conductivity and heat dissipation of lamps are the test of the manufacturing level of manufacturers.

 

In Summary

Users can easily find their own IP6X-rated products by distinguishing waterproof level requirements based on application scenarios; manufacturers can also provide corresponding IP-rated lamps based on application scenarios, and define product waterproof level positioning based on their established market direction. . Whether you are a demander or a supplier, choosing the right product and using it in the right place is the most important thing. Don’t blindly believe in data levels, and don’t think that expensive ones are good. If they are right, they are true!
