Good lamp with light need for improvement

After I had to overcome a few obstacles in assembling the lamp, I am very satisfied with the appearance of the mounted lamp and the light they are. It is recommended, in any case, to combine the Lanmpe with a dimmer, if you want to have a nice lighting.
Somewhat problematic initially developed the attachment to the wall, because due to design, the use of a commercially available screwdriver or even a cordless screwdriver was not possible. I have solved the problem that I have screwed threaded bolts into the wall and the lamp was then secured with nuts in it.
Point deduction is available for the lousy cable connection. At least ferrules could have spendieren the Käbelchen already the manufacturer before being screwed in the terminal block.
