Design of the lamp is great. However, the engineering is embarrassing. The mechanism that holds the pole is just a screw with a nut welded to the end. It does not hold the pole in place and causes it to drop constantly. If you twist it too tight, it will dent the pole. I am an engineer and had to remake the mechanism with my 3D printer. The pole comes in sections and is threaded on each end. The threads were not cut correctly so I had to strip the threads to get them to connect. The threads were also all rusted. I expected more from an almost $400 lamp. Not recommended unless you have the time and resources to address the poor engineering and manufacturing.
