the lamp has an exceptionally beautiful design that is unobtrusive and yet kept brilliant - the supplied 20W G4 bulbs are however extremely hot in the versions and I am afraid that the sockets burn within a very short time, apart from the ecological point of view: it would make sense LED lamps, but to find in a warm tone of a living room, is a challenge that I do not want to expect the dealer that is a private matter but the information is not. Whether the transformer is also suitable for LED, dare I also doubt ...
