What is IP Rating?
When selecting underwater lighting fixtures, one often encounters the enigmatic “IP rating” prominently featured in product descriptions. But what exactly does this cryptic acronym signify? Is it imperative to opt for underwater lights boasting the highest IP rating? If you find yourself grappling with these questions, fear not, for this comprehensive guide is poised to demystify everything you need to comprehend about IP ratings for underwater lighting solutions.
What is IP Rating?
Deciphering IP Ratings
The IP rating, or Ingress Protection rating, is a standardized measure of a product’s ability to withstand intrusion from foreign objects like dust and water. It’s crucial to understand the implications of these ratings when choosing underwater lights to ensure they can withstand the harsh aquatic environment.
Understanding IP Rating Numbers
IP ratings typically consist of two numbers, each indicating a different level of protection. Let’s break down what each number signifies:
The First Number: Protection Against Solid Objects
The first number in an IP rating denotes the level of protection against solid particles. It ranges from 0 to 6, with higher numbers indicating greater protection. For example, a rating of 6 signifies that the light fixture is completely sealed and impervious to dust ingress.
The Second Number: Protection Against Liquids
The second number in an IP rating indicates the level of protection against liquids. This number ranges from 0 to 9K, with higher numbers offering enhanced resistance. A rating of 8, for instance, means that the light can withstand prolonged submersion in water.
Navigating IP Rating Standards
Understanding IP rating standards is essential for selecting the right underwater lights for your needs. Here’s a breakdown of common IP rating standards:
Solid Particle Protection Standard
This standard corresponds to the first number in the IP rating, indicating protection against solid objects.
| IP Protection Class | Solid Size of Protection | Judgment Criteria |
| 0 | Not protected | Not applicable |
| 1 | > 50 mm | Protected against solid objects > 50 mm |
| 2 | > 12.5 mm | Protected against solid objects > 12.5 mm |
| 3 | > 2.5 mm | Protected against solid objects > 2.5 mm |
| 4 | > 1 mm | Protected against solid objects > 1 mm |
| 5 | Dust protected | Ingress of dust is not entirely prevented, but it must not enter in a quantity that would interfere with satisfactory operation of the equipment. |
| 6 | Dust tight | No ingress of dust; complete protection against contact (dust tight). |
Liquid Protection Standard
Conversely, this standard pertains to the second number in the IP rating, signifying protection against liquids.
| IP Protection Class | Detection Method | Judgment Criteria |
| 0 | Not applicable | Not applicable |
| 1 | Dripping Water | Protection against vertically dripping water |
| 2 | Dripping Water (15°) | Protection against dripping water up to 15° from vertical |
| 3 | Spraying Water | Protection against spraying water |
| 4 | Splashing Water | Protection against splashing water |
| 5 | Water Jets | Protection against water jets |
| 6 | Powerful Water Jets | Protection against powerful water jets |
| 7 | Immersion (1 m) | Protection against temporary immersion in water (up to 1 m) |
| 8 | Immersion (>1 m) | Protection against prolonged immersion in water (>1 m) |
| 9k | High-Pressure Steam | Protection against high-pressure steam |
