Different outdoor lights require specific IP (ingress protection) ratings, depending on where they are installed. The IP ratings determine the level of protection provided. For example, IP44 is commonly used for outdoor lights, offering protection against foreign bodies with a size greater than or equal to 1mm and safeguarding against splashing water. In contrast, pond lights necessitate an IP68 rating, ensuring they are dustproof and protected against continuous submersion. Many recessed floor lights utilize IP67, indicating their capability to withstand temporary submersion during heavy rain. To determine the appropriate IP rating for a specific outdoor light, refer to the "Protection class" line.
Here is a brief explanation of the IP ratings commonly associated with outdoor lights:
Solid Protection (First Digit):
0: No protection against contact and ingress of solid objects.
1: Protection against solid objects larger than 50mm in diameter.
2: Protection against solid objects larger than 12.5mm in diameter.
3: Protection against solid objects larger than 2.5mm in diameter.
4: Protection against solid objects larger than 1mm in diameter.
5: Limited protection against dust ingress, but not completely prevented.
6: Complete protection against dust ingress.
Water Protection (Second Digit):
0: No protection against water.
1: Protection against vertically falling water drops.
2: Protection against water drops when the enclosure is tilted up to 15 degrees.
3: Protection against spraying water at an angle up to 60 degrees.
4: Protection against splashing water from any direction.
5: Protection against low-pressure water jets from any direction.
6: Protection against powerful water jets and heavy seas.
7: Protection against the effects of temporary immersion in water up to 1 meter.
8: Protection against continuous immersion in water under specified conditions.
When selecting outdoor lights, it is essential to consider the IP rating to ensure that the lighting fixtures are suitable for the specific outdoor environment and weather conditions in which they will be installed. Higher IP ratings indicate increased protection against dust and water ingress, making the lights more resilient and suitable for use in challenging outdoor settings.
