This is a table lamp, with a direct light suitable for working.
It is constituted by a cardboard tube, plywood for the legs, wood for the support of the lamp (the part that fits in the back of the tube) and the knobs. Apart from these, it needs metal hardware and all the electrical part.
The knobs permit the change of the angle of the tube when unscrewed, and fixing it while screwed. The legs are connected by a wooden bolt.
