Key takeaways
- IP ratings measure protection against dust and water.
- IP65 is dust-tight and water-resistant against low-pressure jets.
- IP67 is dust-tight and can be submerged up to 1 meter.
- Use IP65 for patios and eaves; IP67 for in-ground or submerged lights.
- Check local codes for lighting installations.
Choosing the right outdoor lighting involves understanding IP ratings, which indicate protection against dust and water. This guide explains the differences between IP65 and IP67 ratings, helping you select the best option for your patio, eaves, or garden.
Understanding IP Ratings
The IP (Ingress Protection) rating is a standard used to define the levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies and moisture. The IP code consists of two digits: the first digit indicates protection against solids, while the second digit indicates protection against liquids.
What Does IP65 Mean?
IP65-rated fixtures are fully dust-tight and can withstand water jets from any direction. This makes them suitable for outdoor & landscape lighting applications where lights are exposed to rain but not submerged.
Exploring IP67 Ratings
IP67-rated fixtures are also dust-tight but offer a higher level of water protection, allowing them to be submerged in water up to 1 meter deep for 30 minutes. This makes them ideal for in-ground lighting or areas prone to flooding.
Choosing Between IP65, IP66, and IP67
- IP65: Best for patios and eaves where moderate water exposure is expected.
- IP66: Provides protection against powerful water jets; suitable for more exposed locations.
- IP67: Suitable for in-ground applications or near water features.
Applications for Different IP Ratings
For patio and string & patio lights, IP65 is usually sufficient. Use IP67 for lights in areas that might be submerged, such as ponds or fountains. Always check local codes before installation.
Considerations for Solar Lights
When choosing solar lights, consider the IP rating to ensure they can withstand the elements. An IP65 rating is typically adequate for most solar lighting applications in the US.

Frequently asked questions
What is an IP rating?
An IP rating indicates the protection level of an enclosure against intrusion from solids and liquids.
Can IP65 lights be submerged in water?
No, IP65 lights are water-resistant but not designed for submersion. For submersion, use IP67 or higher-rated lights.
Is IP67 suitable for outdoor use?
Yes, IP67 is suitable for outdoor use, especially in areas where the fixture might be submerged or exposed to heavy rainfall.
Do I need an electrician to install outdoor lights?
For safety and code compliance, hire a licensed electrician for outdoor lighting installations, especially when dealing with electrical connections.
