These warm white, flickering, floating LED tea lights are so cool and so easy to use. Water activated tealights are perfect for weddings and parties. See the short video below! Just place them in your pool, spa, or a tabletop bowl with water (and maybe some other items like flower petals!) and you have a fabulous lighted display with no need for open flame. Instructions: place them on top of liquid of your desire and voila! They light up! These guys come in a set of 12 pieces, each 1.5" tall by 1.5" in diameter, and the batteries are non-replaceable. BUT out of each light you get at least 60 entire hours of use! The body and the "wick" are both white.
