I am very disappointed by this article. Only the color green has an intense light effect. For all other colors, the environment must be to even come close to see a slight glimmer already pitch dark. So you can carry the 400 delivered 500 Starlights confidently into the garbage. And I mean no exaggeration. Probably was saved on lamps. For 500 Starlights the price would have been great. For ultimately only 100 usable it is much too expensive. The article is absolutely not recommended by my side.
