LED Light for Commercial Pools

LED Pool Lamp is an underwater lighting fixture used to illuminate swimming pools for safety/security and aesthetics. The study seeks to analyze performance and effectiveness of LED replacement lamps and LED lighting systems as an alternate to conventional incandescent pool lighting ranging from 300 Watt (W)/R40 to 500W/R40.

Southern California Edison (SCE) conducted the Commercial Light Emitting Diode (LED) Pool Lamps Emerging Technologies (ET) Assessment Project to determine the energy savings, performance, and merits of LED pool lighting. The project assessed LED lighting to replace the incumbent incandescent lighting used in commercial pools for recreational swimming, amateur athletics, and Jacuzzi spas. The project selected five swimming pools and three Jacuzzi spas in three locations in Southern California to survey and evaluate. All five pools and three spas were first surveyed to map the pools’ footprints, specifications of existing lighting, and general characteristics. The data was used to establish the baseline. Existing incandescent lighting within the pools and spas surveyed ranged from 300 Watt (W)/R40 to 500W/R40 120 Volt (V) medium-based socket luminaires. The replacement technologies selected were equivalent LED screw-in replacement lamps and a dedicated (new) LED pool lighting luminaire, as suggested by the manufacturers. The chosen LED lamps and luminaire were then tested in SCE’s Lighting Technology Test Center (LTTC) laboratory to determine their performance. Wattage of the LED lights ranged from 20W to 68W and light output from 729 lumens to over 3,000 lumens per lamp/luminaire.
