What is the main purpose of swimming pool lights?

The primary purpose of swimming pool lights is to enhance visibility and safety during nighttime use. Illuminating the pool area helps swimmers see clearly, which is vital for preventing accidents and ensuring a safe swimming experience after dark. Proper lighting allows users to navigate the pool area with confidence, reducing the risk of slips, trips, and falls.

While creating an attractive ambiance for parties is certainly a benefit of pool lighting, the fundamental reason for having lights installed is to promote safety. Additionally, reducing heat loss from the pool is not a function of lighting but rather related to pool covers and heating systems. Supporting the growth of algae is generally counterproductive and is not a goal associated with proper pool maintenance and operation. Hence, the focus on safety through visibility solidifies the importance of lighting in a swimming pool setting.
