This aurora projector uses dual projection lenses and a four-color Led light source (red, green, blue, and white) to display 14 dynamic light effects and 7 flowing water ripple patterns, creating a flowing starry sky and galaxy effect. It comes with a full-function remote control that supports on/off operation, motor start/stop, strobe mode, three voice control modes, and color switching. Brightness and flow rate can be independently adjusted, each offering 5 levels. Usb powered with a 5W output, it's suitable for various settings such as bedrooms, game rooms, party venues, and children's rooms, making it a thoughtful gift for both children and adults.
