Every summer, most of us are going for a swim. In this article, we are looking at both indoor and outdoor pools.
Design criteria
It is no surprise that indoor pool areas are constantly warm and wet. Even in air-conditioned pools, the luminaires need to resist high humidity and elevated temperatures. Unless the luminaires are very high up, they will be splashed. You need at least IP54 and a higher IP rating is better. Remember that it is the second digit that refers to moisture and water protection.
Some pools have a false ceiling and the void is used to extract the warm, damp air. If you are using a recessed luminaire, remember that the temperature in the void may be higher than the general interior. Also, the upper sections of some recessed luminaires have a lower IP rating than the pool-facing side.
Lastly, don’t forget maintenance. Luminaires positioned over the water will be hard to access – and may cause glare to swimmers doing backstroke!
If an outdoor pool is in a dark location, you might want to delineate its perimeter with a continuous line of light or lines of individual inground units. Since people will be in the pool, it is better to use recessed luminaires rather than surface mounted ones.
Generally, luminaires are recessed into the sides of the pool and the light shines across thus illuminating the swimmers and the opposite wall. Luminaires can also be used in the bottom of the pool to delineate swimming lanes, highlight changes in depth or create patterns.
High wattage luminaires are often installed in a ‘wet’ recess, often called a niche, whereas low power ones can simply be in the dry body of the wall.
Don’t forget that any underwater luminaire must be IP68. The manufacturer should state what is the maximum depth of water the luminaire can be used. If no figure is given, you should assume it is 1m.
One final point to consider for both indoor and outdoor pools is the compatibility of the metal used for the luminaire and the sterilising chemicals used in the water. I know one case where the stainless-steel bezels turned black just a few days after the pool was filled. That was a costly mistake – the profit literally drained away.
