IP68

Video explaining IP68

IP68 lighting is completely dust-tight and resistant to prolonged immersion in water. In this video, we explain what the IP68 protection class means, how it differs from IP67 and IP69K, and when you need IP68 lighting on your truck or trailer.

Meaning IP68

IP68 means completely dust-proof and protected against prolonged immersion in water deeper than 1 metre. The exact depth and duration can vary depending on the specific product and manufacturer. It is therefore always advisable to check the product's documentation carefully.

For vehicle lighting, this means that LED lights continue to function reliably in harsh conditions such as mud, water puddles and wet weather. When intensive cleaning methods are used, such as high-pressure cleaning or steam cleaning, additional protection against water penetration may be required. Then the product needs IP69 or IP 69K.

Is IP68 waterproof?

IP68 is waterproof and protects against long-term immersion under manufacturer-specified conditions. The IEC 60529 standard defines this classification. IP68 products are completely dust-proof and function under water, usually to a depth of at least 1 metre for 30 minutes or longer.

IP68 LED lighting for trucks, tractors and trailers

IP68 LED lighting is commonly found on trucks, tractors and trailers. These lights withstand mud, water and prolonged submersion in accordance with IEC 60529, and operate reliably under harsh conditions. That is why lighting designed to withstand harsh conditions often meets the IP68 standard. These vehicles are exposed to rain, dirt, mud and high-pressure washing on a daily basis. It is precisely in these situations that well-sealed lighting is indispensable. Take a look at our professional trailer rear lights for a durable and reliable lighting solution.

Protection against dust

For IP68, where the "6" stands for the highest dust-tightness rating, it can be said that the device is fully protected against dust and other solid particles. This means that IP68 devices are dust-tight and cannot allow harmful amounts of dust to enter, even under harsh and dusty conditions.

Is IP68 sufficient for your application?

• For rain and splashing water: yes
• For long-term immersion: usually yes (according to manufacturer's specifications)
• For high-pressure cleaning: no → IP69K

Examples of IP68

IP68 is also used in consumer products such as smartphones. For vehicle applications, however, durability and resistance to mud, brine and cleaning are particularly relevant.

Marine applications: Vehicles used in marine environments, such as boats, jet skis or trailers for boats, require lighting that can withstand the corrosive effects of salt water and the impact of waves. IP68 vehicle lighting offers protection against water ingress and ensures reliable operation, even in harsh maritime conditions.

Intensive cleaning

When intensive cleaning methods are used, such as high-pressure cleaning or steam cleaning, additional protection against water penetration may be required. Even then, a higher IP value is important.

IP68 vs IP67 what's the difference?

The difference between IP68 and IP67 ratings lies mainly in their water resistance. Their dust resistance is the same. Both IP67 and IP68 offer the same level of protection against dust, meaning that they are both considered ‘dust-tight’.

Both ratings are designed to prevent dust particles from entering electronic devices, making them suitable for use in environments where dust is a common problem.

IP68 offers a higher degree of protection against water intrusion than IP67. These products can withstand long-term immersion in water under specific conditions specified by the manufacturer, while IP67 only offers protection against immersion to a depth of 1 metre for a limited time.

IP68 vs IP69K: what's the difference?

IP68 and IP69K both offer maximum protection against dust (class 6).
The difference is in the way water loads are tested.

• IP68: protection against long-term immersion under manufacturer's conditions.
• IP69K: protection against high pressure and high temperature water jets (e.g. for high-pressure cleaning or car washes).

Important to know: IP69K does not automatically mean that the product is also suitable for long-term immersion as in IP68K. The testing methods differ.
