IP65 vs IP67 vs IP68: Which Waterproof Rating Do You Need?
Share
What Is an IP Rating?
IP stands for Ingress Protection. The two digits after "IP" tell you how well a light is protected against solid particles (first digit) and water (second digit). For outdoor lighting, the water protection number is what matters most.
IP65 – Splash & Rain Proof
IP65 means the light is fully dust-tight and protected against low-pressure water jets from any direction. This is ideal for:
- Wall-mounted outdoor lights
- Porch and patio lighting
- Garden path lights in mild climates
IP65 handles rain and splashing water easily, but should not be submerged.
IP67 – Temporary Submersion
IP67 lights can be submerged in up to 1 metre of water for 30 minutes. This makes them suitable for:
- In-ground uplights
- Lights near ponds or water features
- Areas prone to flooding or heavy rain pooling
IP68 – Continuous Submersion
IP68 is the highest common rating, designed for continuous underwater use beyond 1 metre. Use IP68 for:
- Underwater pond lights
- Fountain lighting
- Permanently submerged fixtures
Quick Comparison Table
| Rating | Dust Protection | Water Protection | Best For |
|---|---|---|---|
| IP65 | Fully dust-tight | Water jets | Wall lights, path lights |
| IP67 | Fully dust-tight | 1m submersion / 30 min | In-ground, pond-side |
| IP68 | Fully dust-tight | Continuous submersion | Underwater fixtures |
Which IP Rating Should You Choose?
For most garden and outdoor wall lighting, IP65 is sufficient. If you're installing lights near water features or in low-lying areas, choose IP67. Only go for IP68 if the fixture will be permanently underwater.
All SUNSATU outdoor lights carry at minimum an IP65 rating, ensuring reliable performance in rain, wind, and year-round outdoor conditions.
