What Is IP Rating? A Guide to Waterproof Outdoor Lights

When shopping for outdoor lights, you’ve likely seen terms like IP65, IP66, or IP67. But what do these ratings actually mean? The IP (Ingress Protection) rating tells you how well a light is protected against dust and water. For outdoor lighting, understanding IP rating is critical to choosing durable, long-lasting products. This guide breaks down everything you need to know.

What Does IP Rating Mean?

IP rating consists of two digits:

• First digit: Dust protection (0–6)

• Second digit: Water protection (0–8)

• 
  

Higher numbers mean better protection.
