Your swimming pool light<\/strong> is much more than a source of illumination for your nighttime swim. Your swimming pool light is the defining romantic element, designed to illuminate your pool in the darkness, and just as importantly preventing you and your guests from getting injured when you step outside after the sun goes down. Whether you are installing your new first inground pool or replacing the 20 year old halogen lights you used to have, deciding on your ideal swimming pool light impacts your savings, your safety, and your backyard oasis at night.<\/p>\n

Here are all the answers to your decision making questions with regard to swimming pool lighting: types of lights, electrical voltage and codes, lighting options and sizing, installation, and the test of time.<\/p>\n

    What Is a Swimming Pool Light? Types and How They Work<\/h2>\n

    \"What<\/p>\n

    Pool lights are underwater lights that can be attached to the interior walls, floors, or stairs of a swimming pool in order to light the water from within. Underwater pool lights must be either 12 Volts or 120 Volts, have a proper waterproof rating (IP68), and be integrated into a separate electrical circuit with GFCI protection. They 3 uses are for visibility and safety for swimmers, aesthetic ambiance, and Nighttime security.<\/p>\n

    Professional pool builders identify five types of pool lighting depending on how it is installed. Each type is able to accommodate a different type of pool built, retrofit pool as well as related to various budgets. Moving away from incandescent lights and halogen pool lights to LED have been remarkable in magnitude: 90% of US households are now using LED as their primary lighting source according to the U.S.<\/a><\/p>\n

    Energy Information Administration, and a 45W LED pool light is approximately equivalent to 300W of incandescent in terms of light output, but 85% less energy. U.S. Department of Energy<\/a> testing states so.<\/p>\n

    Here is a comparison of the five major types. For a complete list of swimming pool light features and options see the pool lights product resource page<\/a>.<\/p>\n

    Inground niche lights are still the default choice for new pools. The niche\u2014a plastic or metal housing\u2014is installed in the shell before the plaster coat is applied. A rectangular junction box is mounted a minimum of 4″ above the pool waterline.<\/p>\n

    Nicheless pool lights revolutionized the retrofit market. As they screw into the existing 1\u00bd” return fittings, they allow pool owners to add lighting, rather than requiring them to hack into the pool shell. They work particularly well as spa lights and on tanning ledges\u2014where a traditional niche would not fit.<\/p>\n

    Floating pool lights\u2014super easy. No wires needed, run on rechargeable batteries or tiny solar panels, and add color changing light effects to any pool (forget in-ground and inflatable pools too!). Not a replacement for installed underwater lights, but it fills a lot of gaps for renters and seasonal pools.<\/p>\n

    \ud83d\udca1<\/span> Pro Tip<\/strong><\/div>\n

    If you are building a new inground pool, install niche housings even if you plan on using nicheless lights initially. Installing a niche down the road requires draining the pool and cutting into the shell–a $2,000-$4,000 project. Pre-installed niches cost less than $200 during construction.<\/p>\n<\/div>\n

    12V vs 120V Pool Lights: Voltage, Safety and NEC Code Requirements<\/h2>\n

    \"12V<\/p>\n

    Voltage is the topic of every discussion about swimming pool lights. While 12 V introduces your swimming pool light to a power step-down transformer that drops 120 V household current to a safer 12 volts before it reaches the water, 120V operates at full line voltage beneath the surface. Both are Up to Code, NEC Article 680. But they offer very different risks, wiring requirements, and price tags.<\/p>\n
