IP65 rating explained

The Ingress Protection rating is internationally standardized and ensures that lights and other electrical devices do not pose any risk.

What does IP65 mean in lighting?

The first digit of a light or light fixture with an IP rating IP65 means that it is completely protected against contact and against the ingress of dust.

The second digit of the IP code denotes the protection of the light against water jets from all directions.

An IP 65 light and lighting fixture must comply with certain regulations so that they can be labeled with protection class IP65.

Is IP65 waterproof?

The protection against water jets indicates the waterproofness of an IP65 light or lighting fixture. But that is only partially correct. That means,

IP65 is not waterproof; IP65 is water-resistant. “Protected against water jets from any angle, but DO NOT submerge IP65 LED lights as they’re not waterproof.”

For example, a lamp with an IP rating of IP 65 may be hosed down with a garden hose. However, it must not be submerged. For this, at least protection class IP67 is necessary.

Is IP65 rainproof?

IP65 lights are protected against water jets and are therefore ideal for outdoor use. Rain falls at a mild pressure, therefore the IP65 rating is sufficient to keep lights or electrical equipment safe.

Is IP65 suitable for rain?

Yes, the IP65 rating is suitable for rain.

While lights with protection class IP44 should only be attached directly to the house wall or under a roof, IP65 lamps can also be used outdoors when it is raining.

Where are IP65 rated lights suitable?

For which installation locations and environments are IP65 rated lights suitable?

Thanks to the water jet protection from any direction, the lights or lighting fixtures are often suitable for outdoors or for damp rooms.

Where exactly the protection class IP 65 may be used always depends on the exact installation location.

IP65 outdoors

Can IP65 lights be used outside?

Lighting fixtures with IP65 protection can be installed in various places outdoors or in the garden.

The lamps are protected against rain thanks to the protection against water jets from all directions. Thanks to the dust-tightness, no insects can get into the interior of the luminaire and contaminate or damage it.

There is a large number of IP 65 lights and fixtures for outdoor use on the market. The selection ranges from classic LED outdoor wall lights to outdoor spotlights to path lights.

IP65 is waterproof but partially

Especially when using in-ground lights, it should be noted that IP65 outdoor lights are not completely waterproof. If the luminaire can be temporarily underwater at the place of use, protection class IP67 is required.

Is IP65 enough for rain?

The lamps are protected against rain thanks to the protection against water jets from all directions.

Is IP65 OK for bathroom?

In the bathroom and other damp rooms, special care is required due to the combination of water and electricity.

Different requirements and regulations apply here depending on the installation location.

IP65 lights are protected against water jets and may be used in the area above the shower or bathtub up to a height of 2.25m. Their operating voltage must not exceed 25V / AC or 60V / DC.

It’s also worth noting that the majority of shower lights have IP65 rating in any case.

IP65 unsuitable for immersion water

IP65 bathroom lights may really only be used above the shower and bathtub. If these are temporarily underwater, the lights must be protected against submersion water (IP67).

Can IP65 be used in a shower?

With IP65 downlights, you can install entire light protection over your shower or bath without fear of any potential safety hazards (such as electrocution)

Which is better IP65 or IP66?

Both the IP65 and IP66 ratings give good protection against solid ingress from dust, dirt, and debris. The fundamental distinction between IP65 and IP66 classifications is their level of protection against liquid ingress. An IP66 enclosure can withstand substantially more pressured water spray from larger nozzles and at higher kPa ratings.

How strong is IP65?

An IP65 rated fixture is resistant to multi-directional, low-pressure water jets. Fixtures must be able to withstand water projected by a 0.25-inch nozzle in order to pass testing and acquire an IP65 rating.


Lights or lighting fixtures with an IP65 rating are completely protected against contact and dust-tight. Furthermore, they are resistant to water jets from any direction. With this very high level of protection, IP65 lights are a good choice for many installation locations in damp rooms or outdoors.
