The stars are easy to apply, for a room of 5m x 5m ranging thick, so I still have about 1/4 left. Consists of small dots, slightly larger dots, small stars, some bigger star and 4 giant stars. If you just randomly distributes them to the ceiling (in the bright habs done, which was a little tedious, because you the stickers in bright really almost does not see), you get at the end of a nice balanced distribution of stars that looks quite natural. Stick not too Doll, so you no longer have to have no fear in a rented apartment that you would collect these things. Pluses here VA again that one day the stickers really does not see unless you look out exactly!
The room must really be quite dark, so you can see the stars, with us it is unfortunately due to the standing at the door lantern never quite dark, but it is enough for happiness. Better advantage they come but definitely in rooms that can be completely darkened.
The only small downside is that the stars do not charge as much. We Central hangs in space a 1500 Lumens LED lamp, but this it creates only the stars in a radius of about 1m charge. To recharge, the other star good, I have here at Amazon still a UV LED Flashlight (9.99) recovered, with the can charge the star in no time, just over light up briefly and it works!
So I can only recommend the stars, but to charge as I said might prefer to get even a UV lamp.
