Our waterfall lights are completely self-contained, meaning all you need to do is plug them in and watch the custom controller sequence of the lights in a soothing manner. There are 8 sequences of animation with the controller. Each waterfall set made up of ten strands of lights wired. A strand is made of clear wire, each spaced six inches apart for a total of 960 LEDs in a waterfall set. They are great for animated displays in your home, business, or light park. UL listed for indoor and outdoor use.
