What is the primary function of pool lighting?

The primary function of pool lighting is to enhance safety and visibility during nighttime use. Proper lighting allows swimmers to see the pool edges, steps, and any potential hazards, significantly reducing the risk of accidents or injuries when the pool is used after dark. Adequate lighting is essential for ensuring that users can navigate the pool area safely, making it an integral part of pool design and maintenance.

While decorative appearance and the facilitation of nighttime gatherings are important aspects of pool lighting as well, they are secondary to the crucial role that safety and visibility play. Lighting can indeed enhance the aesthetic appeal of a pool and create a festive atmosphere for nighttime events, but these features come after the fundamental need to keep pool users safe in low-light conditions.
