A galaxy projector throws moving clouds, nebula patterns or star dots onto a bedroom ceiling or wall. Some use film discs, others use LED effects with remote or app control, and many add a Bluetooth speaker. They differ a lot in size, power and how much you can adjust.
The six projectors below range from a simple disc projector with a timer to a smart unit with app and voice control. Specs come from each listing page. We have not used these projectors ourselves, and the makers’ coverage and scene counts are their own claims.
