Multi functional: Projection lamp and night light: - Two projection modes (starry sky and sea theme) can be switched between the two modes. Install one of the two films that project different patterns including jellyfish, seahorse, dolphins, clown fish, starfish, algae and shells (sea theme), stars, and moons (star sky theme). Remove both of the inner films and close the top cover, this turns it into a small night light. 8 colour changing modes: warm white and red / blue / green LEDs project 8 colours, beautiful different patterns give you the feeling of being in the middle of the sea or sky. This depends on which projection theme you use. 360 rotation and easy control: the table lamp can rotate 360 and whether you use it in rotation mode or static mode, it offers you an amazing and vibrant view. There are 3 buttons on the front of the night light lamp, you can choose between different colour displays, light rotation and light modes. Energy-saving LED night light: Our projection lamp has 2 power supply modes: 4 AAA batteries (not included) or USB cable (included). If no socket is available, you can use batteries, very convenient and easy to use. Romantic gift for kids: This beautiful projector night light is not only an interesting gift for children, but is also ideal as birthday party decor with its colourful projection patterns. Enjoy the magical starry sky and the stunning underwater world. Note: There are 2 projector films in the projector lamp. One is a starry sky, the other is a sea theme. Please take out 1 of the films before using. Do not use the two projection films at the same time. This night light can be powered by 4 x AAA batteries or a DC 5V input. Do not use the batteries and the USB DC 5V at the same time, as this can damage the product. The lamp can be used as a night light or projector light. If you do not remove the top cover, the light will not be projected onto the wall. In this case the lamp now works as a night light. If you remove the top cover, the light is projected on to the wall and it becomes a projector lamp. Product description: Material: ABS + PVC + PC Power source: 4 x AAA batteries or DC 5 V
