The description of the structure is ok, it was all there, but it is advisable to be in pairs, then just do it more easily. The lamp is assembled then looked askance at first sight, namely in the area of the top two brackets, but with a little back and hergedrehe that was ironed out.
The light is too cold and so the lamp is not intended as placed in the living room, but relegated to the office to read couch. There it fits well with the separately switchable reading arm, the other by means of a rotary knob and can be identified. The floodlights can be dimmed.
The design I find reticent and plain and the light fits optically to many living styles.
The non-exchangeable with the LED light I deliberately only with the other reviewers noted. I must now observe, if the thing goes quickly broken and the whole light can throw then thrown in the trash, which is not very sustainable. But I do not sunk in advance here. Wait how long it keeps.
