IP66
- Updated:
- By: Kevin van Mierlo

What does IP66 mean?
When a product has an IP66 rating, it means it is "dust-proof" and "protected against powerful water jets".
The 6 indicates full protection against dust for extended periods of time, as well as protection against contact with objects larger than 1 mm in diameter.
The second 6 indicates that it is protected against powerful water jets from any direction, such as heavy rain and high-pressure cleaning.
IP-66 Meaning
| First digit: 6 | Full protection against dust particles |

| Second digit: 6 | Protection against powerful water jets |
What is an IP certification?
“IP” stands for Ingress Protection Rating. Now that the name is clear, it’s a little easier to understand. In other words, it indicates how well electronic products such as smartwatches, smartphones and LED lighting are protected against external influences such as water and dust. The IP abbreviation is followed by a two-digit number indicating the product’s protection rating. Below, you can read more about IP66 and other certifications. If you’d like to know all about this, read the general article on all common IP values.
IP66: Dust-proof and resistant to powerful jets of water
Are you looking for a device that can be exposed to dust and powerful water jets worry-free? Then we recommend buying a device with at least an IP66 certificate. If you choose an IP66 product, you can be sure that it is completely dust-proof and resistant to powerful water jets. This makes it ideal for use in tough and challenging environments where equipment is exposed to harsh conditions but does not need to be fully submerged.
Is IP66 waterproof?
Yes, products with an IP66 rating are resistant to powerful water jets. This rating ensures that the product is completely resistant to dust and protected against powerful water jets from any direction. This makes it ideal for use in environments where the product may be exposed to heavy rain or high-pressure cleaning.
The first digit (6) stands for complete protection against dust, while the second digit (6) stands for protection against powerful water jets.
IP66 vs IP67
The main difference between IP66 and IP67 lies in their protection against water. Both ratings offer full dustproofing, but IP66 is specifically designed to withstand powerful jets of water from all directions, such as heavy rain or cleaning with pressure washers. This makes IP66 suitable for environments where the lighting is heavily exposed to water jets but not fully submerged.
On the other hand, IP67 offers protection against temporary immersion in water to a depth of one metre for up to 30 minutes, in addition to being dustproof. By considering these differences in water protection, you can make an informed choice for the right lighting to suit your specific conditions of use.
If you require an even higher degree of protection, IP68 water resistance offers the solution. This IP value indicates that the product is suitable for prolonged submersion in water. This makes it perfect for applications where equipment must operate continuously in aquatic environments.
TRALERT® work lights always have an excellent IP value, ranging from IP66 up to IP69K.
