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 romantic atmosphere in any room! It's perfect for interior decoration, such as mood lighting, night lights, and bedside lamps. Unlike starry sky projectors, this projector features flowing water particles instead of stars. It also features 4 sleep-inducing sounds. The built-in speaker lets you listen to your own music, insert a TF card, or connect it to an external audio source via your phone, computer, or tablet. A silent mode is also available if you prefer. The projector includes sounds of natural forest insects, seagulls and waves, stream birds, cheerful nature sounds, and two lullabies. Studies have shown that natural sounds help you fall asleep. 7 beautiful ocean wave effects: With 7 different color combinations and 45 adjustable angles, the projection area is wider and clearer. You can cover any wall or direction with beautiful aurora borealis as needed. Immerse the entire room in the beauty of ocean waves, and the dynamic projection creates a pleasant and relaxing atmosphere for children before bed or rest. Remote Control and Timer: The ocean wave projection night light features an adjustable 1, 2, or 4-hour auto-off, eliminating the need to wake up in the middle of the night to find the light is off. The remote control also controls all functions, including brightness, timer, and rotation settings. It also supports automatic power off. Pressing H1, H2, or H4 on the remote control indicates the timer setting, automatically shutting off after 1, 2, or 4 hours.
