I’ve purchased these lights before several times in warm white and absolutely love them. So when I saw the purple I had to get them! They are not necessarily waterproof, but definitely water resistant for a good amount of time (like I accidentally forgot them in the hot tub all night and they still kinda worked ?). I don’t necessarily use them for the waterproof feature though. They are just great, long lasting, bright lights that you can put anywhere. FYI, they are definitely purple! The pictures don’t accurately capture the purple color. I would say the top two lights in my Halloween display pic are the most accurate in color.
