Ocean Wave Projector: This 45-degree adjustable ocean wave projector features 12 LED lights and 8 color lighting modes with adjustable brightness. The built-in LEDs rotate freely, projecting beautiful ocean images onto the ceiling and walls, creating a relaxing atmosphere in any room. It's ideal for interior decoration, such as mood lighting, night lights, and bedside lamps. Unlike starry sky projectors, this projector displays flowing water particle effects instead of stars. It includes 4 sleep-inducing sounds and a built-in speaker that allows you to play your own music via TF card or connect to an external audio source using a phone, computer, or tablet. A silent mode is available for those who prefer no sound. Sound options include natural forest insects, seagulls and waves, stream birds, cheerful nature sounds, and two lullabies. Research suggests that natural sounds may help support relaxation. The projector offers 7 ocean wave light effects with different color combinations and a wide projection area. With 45-degree angle adjustment, you can direct the projection to cover walls or ceilings as desired, filling the room with dynamic, soothing visuals suitable for bedtime or relaxation. Remote control operation allows easy adjustment of brightness, timer, and rotation settings. The auto-off timer can be set to 1, 2, or 4 hours using the remote control, providing convenience and energy efficiency.
