Which is best, IP65 or IP67?
Asked by: Brenden Corkery | Last update: April 5, 2026Score: 4.5/5 (3 votes)
Neither IP65 nor IP67 is universally "best"; IP67 offers superior water protection (temporary submersion up to 1m for 30 mins) compared to IP65 (low-pressure water jets), but both provide excellent dust protection, making IP67 better for heavy moisture/flooding and IP65 ideal for general outdoor use with rain or splashes, balancing cost and ruggedness. Choose based on application: IP65 for factory floors or light outdoor fixtures, IP67 for pool areas, docks, or near heavy machinery where submersion is possible.
Is IP65 better than IP67?
An IP65 rated enclosure provides ptotection from low-pressure water jets from any direction. This is suitable for most outdoor enclosures that will not encounter any extreme weather such as water submersion. An IP67 rated enclosure however offers more protection agionast liquid ingress.
Can IP65 survive heavy rain?
Yes, an IP65 rating can withstand heavy rain because the "5" means it resists low-pressure water jets from any direction, which is generally more intense than typical rainfall, making it suitable for outdoor exposure and cleaning, though not for submersion. However, for extremely harsh conditions, prolonged downpours, or potential flooding, higher ratings like IP66 or IP67 offer greater protection against more powerful jets or temporary immersion.
What happens if IP65 gets wet?
Can IP65 devices be submerged in water? No, IP65 devices are not designed to be submerged in water. They can resist water sprays and low-pressure jets, but submersion can lead to damage. For submersion protection, an IP67 rating or higher is more suitable.
Is IP67 ok for heavy rain?
The IP67 meaning signifies that the device is completely sealed against dust and can be submerged in water between 15 cm and 1 meter for short periods. This makes IP67 ideal for outdoor, industrial, and landscape applications where heavy rain, flooding, or temporary submersion may occur.

Is IP67 100% waterproof?
Yes, products with an IP67 rating are waterproof. This rating ensures that the product is completely resistant to dust and can be submerged in water up to a depth of one metre for up to 30 minutes. The first digit (6) stands for "protection against water entering, for example".
What is the difference between IP65 IP66 IP67 IP68?
IP65: The computer is dust-proof and protected from splashes or low-pressure jets. IP66: The computer is dust-proof and protected from strong water jets. IP67: The computer is dust-proof and protected from temporary immersion in water 1 meter deep for 30 minutes.
Is IP65 really waterproof?
For enclosures, the typical waterproof IP ratings are IP67, IP66, and IP65 enclosures. The chart below gives the specifics of what these ratings mean and how they are measured. Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects.
Can IP65 be left outside?
Yes, an IP65 rating is generally suitable for most outdoor use, offering complete dust protection and resistance to water jets, making it great for rain, splashes, and general weather, but for very harsh conditions or temporary submersion, higher ratings like IP67 or IP68 are better. It's ideal for garden lights, outdoor signage, and patios, protecting against dust and low-pressure water spray from any direction.
Is IP65 enough for a shower?
It depends on placement. IP44 is suitable for most areas, but IP65 is best near showers or baths.
What is a good waterproof rating for heavy rain?
A good waterproof rating for most outdoor activities is typically 10,000mm or higher. For heavy rain or extreme conditions, ratings of 20,000mm and above are recommended.
What are the limitations of IP65?
Limitations for IP65-Rated Servo Motors
Motors with an IP65 rating have some liquid resistance but are not fully water submersible. And some applications have strict washdown requirements that IP65-rated motors will not meet without additional protection options.
Can IP65 lights be used in a shower?
Zone 1 is the area above the bath or shower to a height of 2.25m from the floor. In this zone a minimum rating of IP45 is required but it is generally accepted that IP65 is to be used. It's also worth noting that most shower lights are rated at IP65 in any case.
Is IP65 enough for heavy rain?
Yes, an IP65 rating can withstand heavy rain because the "5" means it resists low-pressure water jets from any direction, which is generally more intense than typical rainfall, making it suitable for outdoor exposure and cleaning, though not for submersion. However, for extremely harsh conditions, prolonged downpours, or potential flooding, higher ratings like IP66 or IP67 offer greater protection against more powerful jets or temporary immersion.
Is IP65 safe to submerge in water?
IP65 is not waterproof – it is water resistant. You cannot submerge products that carry an IP65 rating and maintain their protections. Sometimes manufacturers will claim their device is water resistant but they have not performed the IEC testing to the standard.
Is IP65 enough for snow?
If you want an outdoor fixture that stands up to heavy rain and snow, the best IP rating is IP65. A fixture with IP65 is considered water resistant and weatherproof.
What's better, IP65 or IP67?
Water protection is the key difference: IP65: Protected against low-pressure water jets from any direction—ideal for rain, splashes, or cleaning with a hose. IP67: Protected against temporary immersion in water (up to 1 meter for 30 minutes)—ideal for flood-prone or wet environments.
What type of lighting is best for outdoors?
The best outdoor lighting depends on your goal, but LEDs are generally superior for efficiency and longevity, while the type varies: use floodlights for security, path lights for walkways, string lights for ambiance, and solar/dusk-to-dawn options for convenience, with warm white (2700K-3000K) color temperatures creating cozy atmospheres and cooler tones (4000K+) better for tasks and security.
Is IP65 indoor or outdoor?
Each IP water rating consists of two numbers:
For example, an IP54 rating means the fixture is partially dust-proof and resists splashing water from any direction. Meanwhile, an IP65 rating offers complete dust protection and resists low-pressure water jets, making it ideal for outdoor use.
Which one is better, IP65 or IP68?
Most IP65 enclosures also come at a relatively lower price point, so they're a good choice for general applications that need a more basic enclosure. IP68 enclosures should be the choice when you need the most complete protection for your outdoor devices.
Is IP65 suitable for marine use?
Marine electronics will have an IP rating of IP65 or higher and could best be described as weatherproofed. Highly reliable systems will have an IP rating of 66 or higher to ensure maximum protection against moderate pressure jets or low-pressure submersion for short time periods.
How strong is IP65?
IP65 – Dust-tight and protected against water jets
Liquids: 5 – Resistant to low-pressure water jets from any direction. Use cases: Typical use cases include outdoor lighting and enclosures exposed to rain; moreover, this rating suits equipment that may face splashing water but not immersion.
What's better than IP67?
In fact, a device rated IP66 (powerful water jets) can withstand harsh wash-downs better than an IP67 or IP68 device. Always match your application to the specific test behind the rating, not just the number.
Can I upgrade an IP rating?
Can I upgrade a device's IP rating after purchase? Generally, no. IP ratings are determined by the device's original design and manufacturing. While you can add external enclosures for additional protection, this doesn't change the device's official IP rating and may affect warranty coverage.
Is IP65 or IP66 better?
Yes, IP66 is better than IP65 because while both offer complete dust protection (the first '6'), IP66 provides superior water resistance, withstanding powerful, high-pressure water jets, whereas IP65 only protects against low-pressure jets. Choose IP66 for exposed outdoor use, heavy rain, or industrial washdown areas, and IP65 for general outdoor use or sheltered conditions where only light rain or splashing is expected.
