Very good product instead replacing the transformer used as original equipment by IKEA which is infoutu to provide any spare part with a surprising ".... IKEA makes spare part for chandeliers ..." (dixit hot line dedicated to spare parts ..... !!! short! Minor complaint: the thread block composed of a rider held by 3 screws is perfectly useless. If one goes through cedernier, there is no place to put the son in the holes 2 and 3 screws blocking this rider were jammed ... Apart from this great product reproach and suitable price bcp although more expensive than Tranfo 12 V type "lying".
