More often than not, a star projector will come with several light modes, color options, brightness levels, and a sleep timer. Some projectors will also come with a built-in speaker or remote control. Whatever the features, this device is an affordable one that can offer you the magic of starry nights in a dark room, without ever having to step outside. Star projectors can help you relax, enhance your mood and influence your mind.
