The Ocean Wave Ceiling Projector is a remote-activated projector that is super easy to use and has no actual installation necessary. The remote control enables you to set timers for automatic shut-off. It also allows you to change the brightness, chose between 7 wave light colors, and 8 different nature sounds. The audio cable allows broadcasting music from your own device, which will complement the ocean light show. It is adjustable at a 45° angle, allowing you to position the lights at any space in the room.
