Why the star light won't stay still? Is it broken?</br> <br>Hello, it's normal and it's not broken, it's our new design - dynamic star blinking mode. The green stars will not stay still all the time, it will flicker for awhile and then disappear for awhile.</br> <br>2. Is it safe to keep the light on for 12 hours continuously?<br> <br>We suggest that it's better that no more than 4 hours, otherwise the bulbs or led lights will burn out quickly. It's better that power off the star projector for 10mins after using 4 hours, then turn it on again.</br> <br>3. Does the star projector cover the whole room?</br> <br>It would probably cover 25' x 25' or more, because the projection coverage depends on the distance it is from the surface. The farther the projector is from the ceiling, the larger the area covered by the projection.</br>
