IP ratings and weather resistant LED floodlights are a key part of modern lighting solutions. They offer energy efficiency and powerful illumination. However, it is important to ensure the durability and reliability of these fixtures in various environmental conditions. This is where Ingress Protection (IP) ratings come into play. In this article, we will explain the significance of IP ratings and provide valuable insights for installers to choose the right outdoor LED floodlights.
Weather Resistant LED Floodlights: Explaining Ingress Protection (IP) Ratings
When we buy gadgets, we check something called the IP rating to see how well they can handle water, dust, and dirt. The IP rating, set by the International Electrotechnical Commission (IEC) in a standard known as EN 60529, which tells us if a device is tough and safe when it meets people, dirt, dust, or water. It's like a grade that shows how durable and secure an electronic gadget is.
In lighting, IP ratings are a standardised classification system that defines the level of protection a lighting product has against the intrusion of solid particles and liquids. The format of an IP rating is typically "IPXY," where X represents the protection against solid particles, and Y indicates the protection against liquids.
IP65, IP66, and IP67 are Ingress Protection (IP) ratings that indicate the level of protection provided by electrical enclosures, including water-resistant floodlights, against the intrusion of solid particles and liquids. The IP rating is composed of two digits, each providing information about a specific aspect of the enclosure's protection.

Explaining IP 65, 66 and 67
1. IP65:
First Digit (6): Protection against solid objects. Rating of 6 means the enclosure is "dust-tight," meaning it provides complete protection against the entry of dust or other solid particles.
Second Digit (5): Protection against liquids. Rating of 5 means the enclosure is protected against low-pressure water jets from any direction. It indicates that the floodlight is resistant to water splashes and light jets of water.
Note that an IP65-rated floodlight is suitable for outdoor use and can withstand dust and low-pressure water exposure. This level of protection is commonly found in outdoor lighting fixtures where the risk of dust and water exposure is moderate.
2. IP66:
Second Digit (6): Protection against liquids. Rating of 6 means the enclosure is protected against powerful water jets from any direction. It indicates that the floodlight is resistant to heavy rain and strong jets of water.
Note that an IP66-rated floodlight provides a higher level of water resistance compared to IP65. It is suitable for environments where heavy rain and strong water jets are expected.
3. IP67:
Second Digit (7): Protection against liquids.Rating of 7 means the enclosure is protected against the effects of immersion in water up to 1 metre for 30 minutes.
Note that an IP67-rated floodlight is not only dust-tight but can also be submerged in water up to 1 metre for a limited duration without suffering damage. This level of protection is suitable for applications where the floodlight may be exposed to temporary immersion, such as temporary submersion in water.
Choosing the Right IP Ratings for Outdoor LED Floodlights
1. Consider the Environment: For general outdoor use, such as garden or pathway lighting, a minimum IP rating of IP65 is recommended to protect against dust and low-pressure water jets. In areas with high dust concentration or where the fixtures are exposed to heavy rain, an IP rating of IP66 or higher is advisable.
2. Coastal and Marine Environments: Coastal areas are exposed to salt spray, which can corrode fixtures. Opt for LED floodlights with a minimum IP rating of IP67 for enhanced protection against both dust and water, and corrosion resistance.
3. Industrial and Harsh Environments: In industrial settings or harsh outdoor conditions, such as construction sites, choose fixtures with a minimum IP rating of IP68 for maximum protection against dust, water, and submersion.
4. Temperature Extremes: Consider the operating temperature range of the LED floodlight. Some fixtures are designed to withstand extreme temperatures, making them suitable for environments with fluctuating weather conditions.
5. Long-Term Reliability: Selecting fixtures with higher IP ratings not only ensures immediate protection but also contributes to long-term reliability and reduced maintenance costs.
Final Word
It is important for installers to pay attention to IP ratings, as this helps in making informed decisions when selecting outdoor LED floodlights. It's also crucial to prioritise the right balance between solid particle and liquid ingress protection for optimal results in diverse outdoor settings.
