During the process of selecting a luminaire, users will clearly notice that there are two distinct application categories: outdoor or indoor. Once this has been determined, they can then consider the wattage, lumen output and colour temperature.
What must we consider when specifying a luminaire?
Selecting outdoor and indoor luminaires in the past was easier when fewer options were available. Nowadays we use the IP Rating (ingress protection rating) to select the most suitable luminaire for the conditions that it will be installed.
When selecting luminaires for purely interior environments, ideally where there is no chance of exposure to water or humidity, a rating of IP20 will be sufficient to reduce dust.
In semi-outdoor areas such as porches and eaves, high traffic areas like corridors, or wet areas like bathrooms, a minimum rating of IP44 is recommended.
Gardens or outdoor areas that will be exposed to weather and the elements should have a minimum rating of IP54.
In the case of luminaires that will be submerged underwater, for example in a pond, lake or fountain, a minimum rating of IP68 is required in order to prevent water from entering the fitting.
