What is an IP rating?

Definition and purpose of IP protection ratings

An IP rating, or Ingress Protection rating, measures how well a lighting fixture resists intrusion from solids and liquids. This system, defined by the Ingress Protection Code, uses two digits to categorise protection levels. The first digit represents resistance to solid objects like dust, while the second digit indicates protection against liquids such as water. For example, a fixture with an IP65 rating is dust-tight and can withstand water splashes.

Understanding IP ratings helps you choose lighting fixtures that suit specific environments. A fixture with inadequate protection may fail prematurely due to exposure to dust or water. This can lead to reduced luminosity, flickering, or even complete failure. By selecting the right IP rating, you ensure the reliability and longevity of your lighting solutions.

Why IP ratings matter for bathroom and outdoor lamp applications

When installing a bathroom or outdoor lamp, you must consider its exposure to water and humidity. Bathrooms and outdoor spaces often experience high moisture levels, which can damage fixtures with insufficient protection. An IP44-rated fixture, for instance, offers basic protection against water splashes but may not withstand prolonged exposure to heavy rain or steam. For outdoor applications, an IP65 or higher rating is often recommended to ensure durability and safety.

Choosing the correct IP protection rating also enhances practicality. Fixtures with higher ratings perform better in challenging environments, providing consistent lighting without interruptions. This ensures that your bathroom light outdoor lamp remains functional and reliable, even in wet conditions.

💡 Tip: Always check the IP rating of a fixture before purchasing. This ensures it meets the specific requirements of your intended installation area.

Breaking down the IP rating system

The first digit: Protection against solids

The first digit in the IP rating system indicates how well a lighting fixture resists solid objects. This ranges from no protection at all to complete dust-tight sealing. For example, a fixture with a first digit of 0 offers no defence against solid particles, while a rating of 6 ensures no dust can enter the enclosure. The Ingress Protection Code, defined by the IEC 60529 standard, categorises these levels to help you understand the suitability of different IP ratings for various environments.

If you need protection against dust, look for fixtures with a first digit of 5 or 6. These ratings ensure durability in dusty environments, such as workshops or outdoor spaces prone to wind-blown debris.

The second digit: Protection against liquids

The second digit reflects the fixture's ability to resist water intrusion. This ranges from no protection to complete waterproofing for continuous immersion. For instance, a rating of 1 protects against vertically dripping water, while a rating of 8 ensures the fixture can withstand long-term immersion under specified conditions. Standards like IEC 60529 and UL 50E define these levels, ensuring consistency across products.

For outdoor lighting, fixtures with a second digit of 5 or higher are ideal. These ratings provide robust protection against moisture, ensuring reliability in rainy or humid conditions.
