After perpetual back and forth for the parcel service Hermes, everything is now but assumed to our satisfaction. The radiator is functioning properly and lights very bright, as well as my old halogen lamps with 500 watts and a corresponding "heating". However, the connection cable is a joke. 30 cm without plug. Then please without cable, but with terminal block in the transformer box would make more sense. So I had to disassemble the box, loosen the screw and specially get a cable with plug and terminal block. Otherwise top. I'm just on the power-saving trip. Who needs a construction lights or garage lighting in exchange for old halogen spotlight will be well served here. He needs just 49 Watts, measured by Energy Check of Conrad. The case is a bit bigger, but that did not disturb me. Beam is even better than my old halogen spot.
