IP protection classes: the different degrees of protection in lighting

On many occasions, lighting fixtures must stand rough conditions and work for their intended period of time nevertheless they are set out to dirt, dust and humidity. Ingress of liquid and/or solid particles into lighting equipment can not only be harmful to the equipment, it can be dangerous to the operator. Therefore when buying industrial lighting fixtures, it is essential to know what degree of “ingress protection“, also called IP class, or IP rating the product offers. IP codes stands for “ ”  and sometimes also for “International Protection Rating” IP protection classes define how and where the lights can be used without any safety risk.

The protection rating indicates also the protection for people against potential dangers when using the equipment. With regard to suitability for various environments, the systems are divided into relevant IP codes).

 These IP ratings specify the following:

  1. Protection of persons.
  2. Protection of light fixtures (and electrical equipment) against the penetration of solid matter, including dust.
  3. Protection of light fixtures against the harmful effects of water

Explanation of IP Codes

ip protection class

An IP code consists of the letters “IP” and two digits. The first digit is 0…6 and the second 0…9.

Ingress Protection Classification

First Number : Degrees of protection against the infiltration of impurities

Second Number : Degrees of protection against the damaging effects of water

Waterproof led lighting by Airfal applied to urban furniture



The Aranzadi Park is an area of ​​Pamplona in the north of the cit , between the neodighboods Chantrea and Rochapea . Throughout the centuries it has been a dedicated space with green gardens and recreational areas.

This metropolitan area is the second largest of Pamplona .
Some of the plots have been maintained for horticultural use , and other spaces of the forest to the river , keeping their traces and the value of its fruitful soil .

In order not to interfere with the landscape of the park, the architects wanted to use unique street furniture . In the words of the architect and director of works Aranzadi Jesus Arcos, furniture has to have “ simple and pure lines .” “You have to keep in mind what Aranzadi was, and we did not want to have furniture that broke with that environment ,” he said . Some of the banks use are illuminated by four tubular watertight polycarbonate luminaires with LED lighting. The fixtures are made ​​by Airfal International . ”
The illumination with led occupies less space, provides more strength and consumes less , “says Jesus Arcos. The architect notes that this type of lighting was previously installed indoors but this is the first time it is placed in a park , outside , with exclusively designed furniture para the Aranzadi park . Further, he stresses that this design avoids installing more furniture items, as streetlights. Similarly, the same elements that make up the gateway end up being used as picnic .
“It’s an area where many trees have been planted . The result will be like a line of light that is introduced in the forest with trees on both sides , “concludes Jesus Arcos.
The luminaire design had to meet the demanding needs of the project and for this, they used a combination of several models in the catalog of Airfal : Waled , TR1 and Tunnel, and several innovations to get a light with tube opal and IP68, with special reflectors that could be integrated into the urban furniture specially designed for Aranzadi Meander Park .
