IP Ratings Explained
How to read IP dust and water resistance ratings for lighting products.
Water-resistance claims should be tied to the published IP rating. Product photos can suggest rugged use, but ratings must come from verified data.
- IPX4 is water resistance with no dust rating specified.
- Rain resistance is not the same as unlimited submersion.
- Seals, port covers, and switch design all affect real durability.
Key Takeaways
- The first IP digit relates to solid particle protection; the second relates to water ingress protection.
- IPX4 means water resistance is specified, but dust protection is not specified.
- Water resistance is not the same as unlimited waterproof performance in every condition.
How The Rating Is Structured
An IP code uses two protection positions. The first position describes protection against solid objects and dust. The second describes protection against water. When a position is marked X, that part was not specified.
For example, IPX4 communicates a water-resistance level while leaving dust protection unspecified. It should not be rewritten as fully dustproof.
How Buyers Should Use IP Data
Outdoor and work lights should be selected for the expected exposure: rain, splashing, wet hands, dust, mud, or temporary immersion. Higher ratings are valuable only when they match the real environment.
On product pages, show the exact rating from the source catalog. If the product has no published IP rating, avoid replacing it with a generic waterproof claim.
Catalog Data Note
XYX product recommendations on this website should remain tied to the migrated catalog. If a specification is not published for a product, it should stay marked as unavailable until XYX verifies it through testing or updated documentation.
