What IP Rating Do You Need for LED Lighting? Complete IEC 60529 Reference Table
Definition: IP (Ingress Protection) rating classifies how well an enclosure protects against solids (first digit, 0-6) and liquids (second digit, 0-8), defined by IEC 60529.
Applicable Standards: IEC 60529, RoHS, REACH. IP Rating (IEC 60529) is defined as the international standard for enclosure protection. Complete reference table for B2B LED procurement.
Key Takeaways
- IP20 is the minimum for dry indoor use only (living rooms, offices) — no protection against water ingress.
- IP44 protects against splashing water from any direction — suitable for bathrooms and covered outdoor areas.
- IP65 is fully dust-tight and withstands low-pressure water jets — the standard for outdoor wall lights, garden fixtures, and warehouse lighting.
- IP67/IP68 rated fixtures can survive temporary (IP67, 30 min at 1m) or continuous (IP68) submersion — mandatory for pools, fountains, and underwater installations.
- Always verify the second digit independently: IPX4 and IPX5 are not equivalent — IP65 costs 30–50% more than IP44 but provides full dust ingress protection.
IP Rating for LED Lighting: Complete Reference Table (IEC 60529)
IP Rating (IEC 60529) is defined as a two-digit code: first digit (0-6) for solid protection, second digit (0-9) for water protection. Common B2B specs: IP20 (indoor), IP65 (outdoor jet-proof), IP67 (temporary immersion).
| IP Rating | Solid | Water | Typical LED Application |
|---|---|---|---|
| IP20 | Finger-safe | None | Indoor downlights, panel lights |
| IP44 | >1mm | Splash-proof | Bathroom, kitchen |
| IP54 | Dust-protected | Splash-proof | Warehouse, parking |
| IP65 | Dust-tight | Jet-proof | Wall packs, floodlights, facade |
| IP66 | Dust-tight | Powerful jet | Marine, washdown |
| IP67 | Dust-tight | Temporary immersion | In-ground, fountain |
| IP68 | Dust-tight | Continuous immersion | Swimming pool, marine |
B2B Recommendation
Indoor commercial: IP20 min. Outdoor wall/facade: IP65 min. In-ground: IP67 min. Submerged: IP68 with depth rating. Always request IEC 60529 test certificates.
Conclusion
IP Rating defined by IEC 60529. IP65 is the most common outdoor B2B spec. IP67 required for in-ground. IP68 mandatory for submerged. Verify with certificates.
