Unfortunately, the double spokes are not processed approximately parallel, also works with these thin parts the whole lamp only tolerably stable. Well, the glass lampshade and various seals that prevent the entry of rainwater and thus guarantee compliance with IP44 should. Installation is as often in those parts somewhat fiddly (with one hand the lamp included lampshade, keep up with the other, the terminal block and which hand to turn the screwdriver?), Because I've had better for less money solutions seen.
