Supply and installation: The lamp comes in 30 items of cream plastic in a bag. The you have to put together first then. At first I thought, oh ne, bummer Bastelkram, but that is quite fast, is always the same system and even fun. You can customize the lampshade (a completely self-contained "ball") then exactly as desired by the cable clamps around it (by opening the ball at one point something).
Disadvantages: The light is naturally dimmed by the lamp, that is, if you're looking for an ultra bright lighting, this lamp is not suitable (always clear). In the directions also is that the lamp should not be too hot / that you have to be careful with the distance from the light bulb.
