What Is an IP Rating?
IP stands for:
Ingress Protection
An IP rating measures how well a fixture is protected against:
Solid objects (dust, dirt)
Liquids (rain, water)
The rating follows an international standard known as:
IEC 60529
Understanding the IP Rating Format
IP ratings are written like this:
Example:
IP65
The two numbers represent:
| Digit | Meaning |
| First Number | Protection from solids |
| Second Number | Protection from liquids |
First Digit: Solid Protection Explained
| Rating | Protection Level |
| 0 | No protection |
| 1 | Large objects |
| 2 | Fingers |
| 3 | Tools/wires |
| 4 | Small objects |
| 5 | Dust protected |
| 6 | Dust tight |
Second Digit: Water Protection Explained
| Rating | Protection Level |
| 0 | No protection |
| 1 | Dripping water |
| 2 | Tilted dripping |
| 3 | Spraying water |
| 4 | Splashing water |
| 5 | Water jets |
| 6 | Powerful water jets |
| 7 | Temporary immersion |
| 8 | Continuous immersion |
What Does IP65 Mean?
IP65 means:
Dust protected
Protected against water jets
Best For:
- Outdoor wall lights
- Parking lot lights
- Flood lights
- Building exteriors
IP65 is one of the most common ratings for outdoor commercial lighting.
What Does IP66 Mean?
IP66 provides:
Complete dust protection
Protection against powerful water jets
Best For:
- Harsh weather conditions
- Industrial environments
- Coastal areas
- Heavy rain exposure
What Does IP67 Mean?
IP67 means:
Dust tight
Protected against temporary water immersion
Best For:
- Ground lighting
- Landscape lighting
- Wet environments
IP65 vs IP66 vs IP67: Which Is Better?
| Rating | Dust Protection | Water Protection | Best Use |
| IP65 | High | Water jets | Standard outdoor use |
| IP66 | Maximum | Powerful jets | Harsh environments |
| IP67 | Maximum | Temporary immersion | Wet zones |
Which IP Rating Do Outdoor LED Lights Need?
Flood Lights
Recommended:
IP65 or IP66
Area Lights
Recommended:
IP65+
Wall Pack Lights
Recommended:
IP65
Canopy Lights
Recommended:
IP65
Landscape Lights

IP67
Waterproof vs Weatherproof: What’s the Difference?
Weatherproof
- Handles rain and moisture
- Not submersible
Waterproof
- Can handle immersion
Many outdoor lights are weatherproof, not fully waterproof.
Why IP Ratings Matter for Outdoor Buyers
