Be careful with these spotlights, although they emit sufficient, but the protective conductor is clamped under the cover !!! This means that the wires are not stripped in the housing is located. I have already opened three housing and at two of the insulation conductor or neutral conductor were damaged. If it now comes to a short circuit, then the FI switches off the fuse or you get an electric shock. As I said, the brightness is sufficient for 10W. The bracket is wrongly dimensioned. He goes on the side of the chassis. For the money I would actually give 3 star (maybe even 3.5 stars), if the risk of electric shock would not.
