Challenges and solutions for indoor pool lighting – standard

Safety, resistance, durability: these are three required qualities of any indoor pool lighting system. Any installation of this type is a multi-faceted one and requires careful examination of several features prior to the selection or refurbishing of its lighting arrangement. Initially, we need to establish the end-use of the pool; we further need to study the rules and regulations governing lighting in such an environment. Further, we must address the safety dimensions for swimmers and pool staff. Finally, both the resistance and durability of selected luminaries require thorough compliance. 1) Assessing the End-Use of the Pool to Select Appropriate Lighting

Is this pool situated in a condominium or a hotel? Will swim meets be held in this pool?


Will they be televised? Will swimming or diving lessons be given there? Will the pool serve as a water polo facility or leisure swim centre? It is essential to specify to what end the pool will be used prior to selecting the lighting system needed because a number of activities require that certain standards be applied to ensure safety standards are met.

Most provinces and territories in Canada have published guidelines with respect to the maintenance and operation of pool facilities, yet there are no official standards in effect in this country. In most cases, the basic installation calls for a minimum of 200 lux over the surface of the pool, both during the day and at night. There should be sufficient lighting so that every surface of the installation is clearly visible; this includes the bottom of the pool as well. In Quebec, the construction code issued by the Régie du bâtiment is more demanding than its provincial counterparts: it insists on the use of 300 lux. However, many installations (even new ones) fail to meet these regulations.

One of the major concerns that stands out regarding lighting in a pool installation is the quality of light, as it affects the safety of people who use the pool as well as those responsible for its upkeep. Particular attention needs to be paid to the reflection of light on the pool’s surface and on its surroundings. The glare can cause discomfort or even dizziness to the pool attendants.

It is important to examine the Unified Glare Rating (UGR) of chosen lighting products. The UGR is a method used to estimate the glare factor, as defined by the International Commission on Illumination. Typically, a UGR measuring less than 10 is of no consequence. Conversely, a rating above 30 indicates a high degree of brightness. 4) Luminaires that are Resistant to Chlorine and a Humid Environment

Pools are known to be highly humid and corrosion-causing environments; the lifespan of luminaires installed in this setting can be affected. The level of humidity is usually quite high (approximately 50 to 60%) in indoor pool facilities as are chlorine vapors, which accelerate corrosion of materials. In addition to this, the basic configuration of pools tends to make lighting system maintenance a difficult and costly job. For these reasons, lighting installations need to be both resistant and durable.

LED luminaires have greatly evolved over the last few years. They are more resistant; they project much less heat; they are less energy intensive than in the past and they have a longer lifespan than their traditional counterparts. Their durability is a key factor in the low maintenance of these lighting systems, especially in a costly environment such as indoor pools.
