Best IP Ratings for Outdoor Lights in Rain (IP44–IP66)

What IP rating for outdoor lights in rain?

For outdoor lights exposed to rain, a practical minimum is IP44 for sheltered locations (like under a covered porch) and IP65 for fixtures that will be directly hit by rain on open walls, fences, or exterior columns. If the light is near ground level where puddles or hose spray is common, stepping up to IP66 can add extra peace of mind.

How to read IP ratings (quickly)

An IP rating has two digits. The first digit covers protection from dust/solids; the second digit covers protection from water. For rain performance, the second digit matters most:

IP44 = protected against splashing water from any direction (good for damp, partially covered areas).
IP54 = limited dust ingress + splashing water (often fine for covered exterior walls).
IP65 = dust-tight + water jets (better for wind-driven rain and exposed installations).
IP67 = temporary immersion (usually more than needed for wall lights, but useful near grade or in flood-prone spots).

Choosing the right IP rating for your location

Covered entries and soffits: IP44 is commonly sufficient when the fixture isn’t getting directly rained on.
Open exterior walls: IP65 is a strong choice for heavy rain, storms, and sideways spray.
Coastal or dusty environments: prioritize a higher first digit (5 or 6) to reduce grit intrusion, then match the water rating to exposure.
Near sprinklers, hoses, or car wash zones: IP65 or IP66 helps handle frequent direct spray.

Don’t forget installation details

Even a high-IP fixture can leak if it’s installed poorly. Use the correct gasket, keep cable entries sealed, and ensure the fixture sits flush on a flat mounting surface.

FAQ

Is IP44 good enough for a covered porch light?

Usually, yes. If the fixture is under a roofline and only gets occasional splashes or wind-blown mist, IP44 is typically appropriate; choose IP65 if the area still gets direct rain.
