Underwater pool lighting is a surefire way to add to the wow factor of your pool. Pool lighting can enhance a pool’s visual appeal, add visibility or even change the overall mood of the pool with lights that change colors. With recent advancements in underwater lighting technology, it is important to understand the proper terminology, code standards and industry trends in order to successfully navigate the sometimes confusing world of underwater pool lighting.
Design of underwater lighting for the commercial pool industry has typically been based upon watts per square foot of water surface area. Wattage ratings for pool lights, however, are nearly obsolete, since incandescent lights are becoming a thing of the past. The latest and greatest lighting trend taking over the aquatics industry is light-emitting diode (LED) lighting. LED lights use much less energy and can last five times longer than a comparable incandescent light.
