IP rating refers to ingress protection rating or international protection ratings, which are used to qualify levels of dust- and water-sealing effectiveness. It is crucial to consider IP ratings if you are purchasing fixtures for dusty or wet environments.
An IP rating is defined by the letters IP, followed by two numbers. Its sole purpose is to provide accurate information about the protection level an electrical fixture offers. The first digit offers a scale of 0–6 and relates to the protection levels against solids like dirt, sand, dust, and debris, while the second digit (0–8) represents protection against liquids like moisture and water. The higher the number, the greater the protection against solids and liquids. The first digit indicates the level of protection against solid objects and dust ingress.
Main Differences Between IP65, IP66, and IP67
Depending on your project, the differences between these three ratings can be very important. A fixture rated with any of the three of these ratings is equally protected against dust, dirt, sand, and debris (as indicated by the “6” digit). The liquid/water protection for each of these three ratings is unique.
- IP65 – Water resistant
- IP66 – Water resistant against powerful jets
- IP67 – Protected against complete temporary water submersion
High-IP-rated fixtures are essential for harsh environments where dust and water are prevalent.
Which IP Rating Do I Need?
The answer to this question ultimately depends on the environment in which your fixtures will be installed. If your fixtures will be subjected to dust, sand, debris, or liquids, choosing a fixture with a higher IP rating is advised. To decide which IP rating is suitable for your project, examine the space where the fixture will be placed. Typically, low IP ratings are used for areas such as indoor settings where jetting water will never be an issue. Temperature controlled areas like office buildings and municipal buildings would not require high IP ratings. High-IP-rated fixtures are used for outdoor locations subjected to a greater amounts of liquids and dust, areas with a large footfall, wet locations, and unsealed locations, such as sports arenas, beachfront areas, and dirty warehouses.
IP65 Fixtures
A fixture with an IP rating of 65 is protected against multi-directional, low-pressure water jets. In order to pass testing and achieve an IP65 rating, fixtures must be able to withstand water projected by a 0.25-inch nozzle. To achieve satisfactory results, this test must be run for a minimum of fifteen minutes, with the water source placed three yards from the fixture. Additionally, the water pressure must be 30 kPa with a water volume of 3.3 gallons per minute. IP65-rated fixtures are commonly used in electrical enclosures to protect against low-pressure water jets.
Access Fixtures has many IP65 rated luminaires in many styles and for many applications. Here are just some of the Access Fixtures IP65 fixtures available for purchase.

IP66 Fixtures for High Pressure Water Jets
An IP66 rated fixture is protected against multi-directional, high-pressure water jets. To pass IP66 testing, the fixture must be able to withstand water projected from 0.50-inch nozzle, multi-directional, high-pressure jets. This test must be run for a minimum of three minutes, at a distance of three yards, with a water volume of 26.4 gallons per minute and a pressure of 100 kPa. IP66-rated fixtures are also dust tight, providing complete protection against dust ingress.
