Have you ever wondered what the IP rating on LED lights means? Many customers overlook this parameter when purchasing lamps, not fully understanding its significance. In this article, we will explore how to choose the right IP rating for your LED lights, ensuring you make the best choice for your needs.
Understanding IP Ratings
The IP rating, also known as the Ingress Protection rating, is an important indicator of a lamp's resistance to solid objects and liquids. It consists of two numbers, each representing a different aspect of protection.

First Number: Dustproof Level
The first number in the IP rating signifies the lamp's ability to resist solid objects. The higher the number, the more effectively it prevents dust and debris from entering the lamp. Common IP ratings in the LED lighting industry include IP22, IP44, and IP54. These ratings are typically suitable for indoor use, where the risk of dust is relatively low.
Second Number: Waterproof Level
The second number in the IP rating indicates the lamp's waterproof capability. It determines its resistance to liquid or moisture. IP ratings like IP65, IP66, IP67, and IP68 are often used for outdoor lighting applications, as they offer varying degrees of protection against water ingress.

Understanding Different IP Ratings
Let's take a closer look at the different IP ratings and their applications:
IP22 LED Lighting and Applications
IP22-rated lights can prevent solid objects with a diameter of 12.5mm or larger from entering the lamp. They also provide protection against liquid ingress when tilted at a 15-degree angle. These lamps are suitable for dry indoor environments with minimal dust. They are commonly used in living rooms, bedrooms, offices, schools, and supermarkets. Examples of IP22-rated lights include LED downlights, LED panel lights, LED tube lights, and LED track lighting.
IP54 LED Light Fixture and Application
An IP54 rating ensures that dust will not adversely affect the lamp. Instead, the focus is on its waterproof ability. IP54-rated lights can withstand water splashing from all directions without causing damage. They are suitable for indoor environments with higher humidity, such as kitchens, bathrooms, toilets, and outdoor balconies. Examples of IP54-rated lights include moisture-proof LED downlights, flush mount ceiling lights, and dust-proof battens.
IP65 Waterproof Lighting Fixture and Application
IP65-rated lights offer increased waterproof protection and can be used both indoors and outdoors. They are suitable for more complex application environments, including mines, chemical plants, and places that require explosion-proof lighting. IP65-rated lights effectively prevent external dust from entering and provide ordinary waterproofing. Common IP65 waterproof LED lights include outdoor landscape lights, outdoor floodlights, street lighting, high bay lights, and LED battens.

IP66 LED Lighting and Application
Similar to IP65, IP66-rated lights offer a higher level of waterproof protection. Although they are not designed to work underwater, they are stronger in terms of their waterproof function. IP66-rated lights are commonly used for inground lights, outdoor spotlights, and other outdoor applications.
IP67 Waterproof Lighting and Application
IP67-rated lights are capable of working underwater, making them suitable for installations near water. However, they should not be installed in places with deep water. Common applications for IP67-rated lights include ground fountains, poolside lighting, and other outdoor installations. Manufacturers may also upgrade certain outdoor lights to IP67 protection level upon customer request, resulting in longer lamp life. Underground lights and deck lighting are examples of IP67-rated lights.
IP68 Waterproof Lighting and Application
IP68 is the highest level of protection, suitable for any environment in daily life. These lamps are skillfully crafted and often made of 304 stainless steel to prevent rust and corrosion. Due to their underwater installation, most IP68-rated lamps operate on AC/DC 12V or 24V input, ensuring safety. However, IP68-rated lights tend to be more expensive due to their advanced features.
Conclusion
When choosing LED lights with the appropriate IP rating, it is essential to consider the specific installation environment. For indoor environments, IP54 lamps generally meet all requirements. In non-humid environments, IP22 lamps are more suitable and often more affordable than IP54 lights. For outdoor use, IP65 or IP66 ratings are sufficient unless the lights need to be installed underwater. In such cases, it is recommended to opt for IP68-rated lights.
