IP67 vs IP68 for Off-Road LED Lights – What Do They Mean?
When shopping off-road LED lights, you will always see IP ratings like IP67 and IP68 listed on product specs. But what exactly do these numbers stand for? And which one is better for 4×4, trucks and heavy-duty offroad use?
IP stands for “Ingress Protection”. It measures how well a product can resist dust and water intrusion. The first digit refers to dust protection, the second digit means water resistance.
What is IP67?
- First digit 6: Completely dust-tight. No dust can get inside the lamp housing.
- Second digit 7: Protected against temporary immersion in water.
The standard for IP67 means the light can be submerged in 1 meter of water for up to 30 minutes.
Practical use:
IP67 LED offroad lights handle heavy rain, splashing mud, and temporary water crossing. It is the most common rating for entry and mid-range off-road LED lights.
⚠️ Limitation: IP67 is NOT designed for long-time underwater use. Do not keep it submerged for hours.
What is IP68?
- First digit 6: Also fully dustproof, same as IP67.
- Second digit 8: Protected against continuous immersion in deep water.
Manufacturers define the depth and duration. Normally it means submersion deeper than 1 meter for over 1 hour.
Practical use:
IP68 is the higher grade. It works well in extreme muddy, rainy environments and longer water crossings. For premium off-road light bars, work lights, IP68 is the top choice.
IP67 VS IP68 Quick Comparison
- Dust protection: Both IP67 and IP68 are fully dustproof (6).
- Water resistance: IP67 = temporary submersion; IP68 = continuous deep submersion.
- Cost: IP68 lights usually cost more than IP67 versions due to stricter sealing structure.
- Common market: Most wholesale 4×4 lights adopt IP67. High-end aftermarket kits choose IP68.
Important Note:
A printed IP rating only matters if the lamp housing, rubber gaskets, cable joints are all well sealed. Poor assembly will lead to water leakage even if marked IP68.
When you source off-road LED lights, confirm real waterproof test reports instead of only checking the spec sheet.
Which one should you buy?
- For general 4×4 daily driving, rain and occasional mud: IP67 is sufficient and cost-effective.
- For heavy offroading, frequent deep river crossing, harsh weather: Choose IP68.
