These disc lights are designed to work well when placed under a waterfall or other curtain of water. They can also be placed around the pond as floor lights or hidden beneath the kip of a fountain.
The color-changing light does not have a controller, but instead runs through a pre-programmed sequence. Note:These lights work independently of each other and will be difficult or impossible to synchronize. If you want to coordinate several color-changing lights to operate in synchronization, it is better to buy a light set with common controller.
