IP Ratings – What Are They and Why Are They Important?
An IP rating stands for Ingress Protection (also called International Protection) rating. It is the internationally recognised standard used to quantify how effectively an electrical enclosure — such as a waterproof outdoor wall light — is sealed against dust, dirt, debris and water.
When you are buying lighting fixtures for dusty, wet or fully outdoor environments, the IP rating is one of the most important specifications you should check. It tells you, at a glance, whether a fixture can survive years of rain, spray, sand or condensation without failing.
Understanding the two-digit IP code
An IP rating always begins with the letters IP, followed by two numbers:
- First digit (0–6) — protection against solids: dirt, sand, dust and debris. 6 = completely dust-tight.
- Second digit (0–8) — protection against liquids: moisture, drips and water jets. The higher the number, the better the waterproofing.
In short: the higher the number, the greater the protection against both solids and liquids.
Which IP Rating of Waterproof Outdoor Wall Lights Do I Need?
The answer ultimately depends on the environment where your fixtures will be installed. If your lights will be exposed to dust, sand, debris, or liquids, choosing a higher IP rating is strongly advised.
To decide which rating suits your project, examine the space where the fixture will be placed:
Low IP ratings — indoor & controlled spaces
Typically used for indoor settings where water jets and heavy moisture will never be an issue — for example, temperature-controlled areas such as office buildings and municipal buildings. These spaces do not require high IP ratings.
High IP ratings — outdoor & harsh environments
High-IP-rated fixtures are essential for outdoor locations subjected to greater amounts of liquids and dust, areas with large footfall, wet locations, and unsealed locations, such as:
- Sports arenas & stadiums
- Beachfront & coastal areas (salt spray + sand)
- Open warehouses & industrial sites
- Garden, patio & façade wall lights
- Hotel & resort outdoor corridors
For most exterior wall-mount applications, IP65 or higher is the safe standard.
IP65 Fixtures – Water Resistant (and IP66 / IP67)
Depending on your project, the differences between IP65, IP66 and IP67 can be very important. A fixture rated with any of these three ratings is equally protected against dust, dirt, sand and debris (as indicated by the "6" digit). The difference lies in the liquid / water protection — the second digit.
IP65 – Water resistant
A light fixture with an IP65 rating is protected against multi-directional, low-pressure water jets. To pass testing and achieve an IP65 rating, fixtures must meet strict conditions:
- Withstand water projected from a 0.25-inch nozzle
- Test runs for a minimum of 15 minutes
- Water source positioned 3 yards (≈ 2.75 m) from the fixture
- Water pressure of 30 kPa, at a volume of 3.3 gallons per minute
This makes IP65 the ideal, cost-effective choice for most outdoor wall lights — fully dust-tight and rain-proof from every angle.
IP66 – Protected against powerful water jets
IP66 offers the same dust protection as IP65, but withstands stronger, high-pressure water jets — suitable for areas exposed to heavy hose-down, driving rain or sea spray.
IP67 – Temporary immersion protection
IP67 fixtures can survive temporary immersion in water (up to 1 metre for 30 minutes). Best for locations prone to flooding, ground-level washdown, or very wet coastal installations.
How to Choose the Ideal Waterproof Wall Light Fixture
When selecting the right waterproof wall light for your home, hotel or commercial project, keep these tips in mind:
- Match the rating to the environment: gardens and covered patios → IP65; exposed façades and beachfront → IP66; flood-prone areas → IP67.
- Prioritise build quality: look for sealed aluminum housings, tempered glass and silicone gaskets for long-term weather resistance.
- Don't over-spec unnecessarily: IP67 costs more — if you don't need immersion protection, IP65 delivers excellent value for most outdoor walls.
- Consider style & colour temperature: pair your IP rating with a design that complements your architecture (warm 3000K for hospitality, crisp 4000K for modern façades).

Frequently Asked Questions
What does IP rating mean on outdoor lights?
IP (Ingress Protection) rating defines how well a light fixture is sealed against solids (first digit, 0–6) and liquids (second digit, 0–8). The higher the number, the stronger the protection.
Is IP65 enough for outdoor wall lights?
Yes. IP65 means the fixture is fully dust-tight and protected against low-pressure water jets from any direction — suitable for most outdoor walls, patios, gardens and hotel facades.
What is the difference between IP65, IP66 and IP67?
All three are dust-tight (digit 6). IP65 resists low-pressure jets, IP66 resists powerful high-pressure jets, and IP67 can survive temporary immersion in water.
Conclusion
Understanding IP ratings is essential when selecting waterproof outdoor wall lights. Whether you need IP65 for residential exteriors, IP66 for commercial facades, or IP67 for flood-prone areas, choosing the right rating ensures longevity, safety, and optimal performance.
Remember: The higher the IP rating, the better the protection—but always match the rating to your specific installation environment for the best value.
