KO criterion and reason for return, however, was that the lamp has made impossible by electromagnetic interference to radio reception. The receiver 5m remote no interference-free reception longer possible, you have asked the lamp next to the radio, was only noise because, in DAB mode the signal went to 0%. I have compared with another LED uplight the same price range, this affects the reception also right next to the radio in any way.
Since interference to other equipment or in the vicinity can not be excluded, can only advise against this product. 1 star because 0 is not possible.
