When choosing an LED power supply, understanding the IP rating is essential. It indicates how well the device is protected against dust and water, which is critical for outdoor or wet-location installations. Two common ratings are IP67 and IP68, but what do they actually mean—and how do they differ?

Understanding IP Ratings

The IP (Ingress Protection) rating consists of two digits:

• First digit – Solid particle protection: 6 = Dust-tight, completely protected against dust ingress.
• Second digit – Liquid ingress protection:
  • 7 = Protected against temporary immersion in water (up to 1 meter for about 30 minutes)
  • 8 = Protected against short-term immersion or higher water pressure, but not intended for long-term submersion

IP67 LED Power Supply

An IP67-rated power supply is ideal for environments where it may occasionally get wet, such as:

• Outdoor signage exposed to rain
• Lights near fountains or water features
• Temporary outdoor lighting

IP67 units offer reliable protection in these conditions without additional waterproofing.

IP68 LED Power Supply

IP68-rated power supplies offer higher water resistance than IP67, suitable for high-humidity environments or short-term immersion, such as:

• Outdoor lighting exposed to splashes or heavy rain
• Fixtures occasionally covered by water
• Humid outdoor or semi-outdoor installations

Choosing the Right Rating

• Choose IP67 if your LED system experiences occasional rain, splashes, or short-term immersion.
• Choose IP68 if the environment is highly humid or occasionally wet, but not for permanent underwater applications.

✅ Safety first: It’s always better to slightly overestimate the water protection needed to ensure reliability and reduce maintenance.

Conclusion

Both IP67 and IP68 LED power supplies are excellent for outdoor or damp environments, but knowing their limitations is key. IP67 is sufficient for most general outdoor installations, while IP68 provides extra protection for short-term immersion or high-humidity scenarios.
