Simply install one of the two films included to project various patterns, such as jellyfish, sea horses, dolphins, and more in the sea world theme, or stars and moons in the starry sky theme. The lamp also functions as a little bedside night light when the inner films are removed and the top cover is closed. With 8 colors mode, the warm white and colored LEDs can project 8 different colors, allowing your child to feel like they're staying in the middle of underwater or becoming a star rover, depending on the projection theme they choose.
