Einzies shortcoming of the whole story, as well as already have noted the other reviewers who cabling. Although it included an extension cord, but to hide the transformer and this weird control unit, you might actually be needed longer cables to the einzelenen modules, so you can distribute them everywhere in the room. I have written a corresponding email to Osram, because so far the extension cord is not sold separately. (If anyone does not need his, like ne email to me!).
But still great lighting that looks the uplight replaced very beautiful and more elegant.
