one of the few bad reviews from me. Two items have been ordered for the kids. One of them works flawlessly so far, the other was quite soon the ghost. When we complained, I was asked to take photos of the installation situation, etc. I had to to this day do not feel like the thing to work, I think that's harassment. I waive my money and Warne times really BIG. Two points, because one of the two ordered bulbs work. Incidentally, more air for convection like me, there's probably only rarely. It is at the Childrens bedroom lighting as balloon-like ball made of paper, with a diameter of 80 cm. Below and above the paper ball has a hole where one can reach by hand. In the center of the sphere then the version with the light source. Ifs it gets too hot, I do not know anymore.
