Edit: the humming was due to the light source, with a different LED the dimming is silent.

Good day, I ordered the above-mentioned luminaire but found out that the one I received is only suitable for lamps up to 5W (indicated directly on the lampholder and on the box). In the product description on this page, this value is stated as 9W. Are there two different versions or is it an incorrect product description? In both cases an annoying situation, as I already have the lamp with 5.5W and had selected the luminaire according to this, among other things. Possibly helpful information for other interested parties: the dimmer hums quite loudly. The feel and finish are very nice.
