The 6 Best Underwater Pool Lights

This wiki has been updated 21 times since it was first published in February of 2019. Why stop swimming when the sun sets? Underwater lights can add hours of fun and relaxation in your pool after dark, whether you’re entertaining guests or just winding down from a day's work. A well-lit area creates ambiance and helps keep nighttime swimmers safe. Here we rank models for durability, brightness, and price. Note that these devices should be installed by a licensed electrician. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki.
