IP Ratings for LED Lights: Outdoor & Waterproof Guide
IP ratings have two digits: the first (0–6) rates solid particle protection, the second (0–9) rates water protection. IP65 handles rain, IP67 survives temporary submersion, and IP68 withstands continuous submersion. For outdoor LEDs, IP65 is the minimum.
Don’t over-spec or under-spec. IP44 is fine for covered patios. IP65 handles open outdoor use. IP67/68 is only necessary for in-ground, underwater, or heavy-wash environments.
What Are IP Ratings?
IP stands for "Ingress Protection" and is defined by the international standard IEC 60529. The IP code classifies the degree of protection provided by enclosures against the intrusion of solid objects (dust, fingers, tools) and liquids (drips, sprays, submersion).
An IP rating consists of two digits: IP[solids][liquids]
For example, in IP65:
- 6 = totally dust-tight
- 5 = protected against water jets from any direction
First Digit: Solid Protection
| Digit | Protection Level | Object Size |
|---|---|---|
| 0 | No protection | — |
| 1 | Large body parts | > 50mm |
| 2 | Fingers | > 12.5mm |
| 3 | Tools, thick wires | > 2.5mm |
| 4 | Most wires, screws | > 1mm |
| 5 | Dust-protected | Limited ingress |
| 6 | Dust-tight | No ingress |
For LED lighting, you’ll almost always see 5 or 6. Anything less would allow insects and debris into the fixture.
Second Digit: Water Protection
| Digit | Protection Level | Test Condition |
|---|---|---|
| 0 | No protection | — |
| 1 | Dripping water | Vertical drops |
| 2 | Tilted dripping | 15° tilt |
| 3 | Spraying water | 60° angle |
| 4 | Splashing water | Any direction |
| 5 | Water jets | 6.3mm nozzle, any direction |
| 6 | Powerful water jets | 12.5mm nozzle |
| 7 | Temporary immersion | 1m for 30 minutes |
| 8 | Continuous immersion | Depth specified by manufacturer |
Common IP Ratings for LEDs
IP20 — Indoor only. Standard for interior ceiling fixtures, desk lamps, and LED panels. No water protection.
IP44 — Splash-proof. Suitable for covered outdoor areas (porches, covered patios) and bathroom Zone 2 (60cm from water sources).
IP65 — Jet-proof. The standard for outdoor LED strips, floodlights, and garden lighting. Handles rain, sprinklers, and general outdoor weather.
IP67 — Submersible (temporary). Can survive being dropped in a puddle or briefly submerged. Good for in-ground pathway lights.
IP68 — Submersible (continuous). Used for pool lights, fountain lighting, and underwater applications.
How to Choose the Right IP Rating
| Location | Minimum IP | Recommended IP |
|---|---|---|
| Indoor (dry) | IP20 | IP20 |
| Covered outdoor | IP44 | IP44–IP65 |
| Open outdoor | IP65 | IP65 |
| In-ground | IP67 | IP67 |
| Underwater | IP68 | IP68 |
| Bathroom (Zone 1) | IP65 | IP65 |
| Bathroom (Zone 2) | IP44 | IP44 |
| Commercial kitchen | IP65 | IP65 |
Frequently Asked Questions
Is IP65 waterproof?
IP65 is water-resistant, not waterproof. It protects against water jets (like rain or a garden hose) but cannot be submerged. For true waterproof performance, you need IP67 (temporary submersion) or IP68 (continuous submersion).
What IP rating do I need for a bathroom?
It depends on the zone. Directly above a shower or bath (Zone 1): IP65 minimum. Within 60cm of a water source (Zone 2): IP44 minimum. Rest of the bathroom: no specific IP requirement, but IP20+ is good practice.
