A ceiling instead of a sky, and two very different kinds · review
A room star and aurora projector with adjustable brightness and speed, a remote control and an auto-off timer settable from half an hour to four hours.
The bottom line A bedroom light that borrows the vocabulary of astronomy — pleasant, and not an instrument.
A room projector. It throws stars, clouds and an aurora effect onto a ceiling, in colour combinations of red, green and blue. It is filed on this site because it is sold as astronomy, and the first thing a reader needs to know is that it shows a decorative pattern rather than the sky above the house.
Five timer steps — half an hour, one, two, three, four — with a cancel button. Adjustable brightness and adjustable speed. A remote control with several modes. Those are stated plainly and they are the features a buyer actually uses.
Brightness in any unit, the area it covers, the power it draws, or the light source. None of it appears, which places this alongside most of its category.
A child’s room, a party, a quiet evening. For a child already interested in the sky, the natural companion is a planisphere — the one that shows what is actually outside.
German, French, Italian and Spanish Amazon stores ran from 19 € to 24 € on the day of the survey.
American and British Amazon stores gave no result whatever, so the buy button there opens a search rather than an empty page.

No. It projects a star field and an aurora effect chosen for appearance. A planetarium projector that shows the actual sky is a different product, and this listing does not claim to be one.
Because it is usually switched on at bedtime. Five named steps from half an hour to four hours, plus a cancel, is a more useful specification than most of what appears in this listing.
