In the green version, the glass undergoes a colouring process with external painting. A borosilicate glass cylinder acts as a diffuser for the light cast by the light bulb and becomes the decorative element in the volume of the diffuser glass. The steel base undergoes several acid-etching processes and subsequently coated with transparent liquid paint; electrical cable and dimmer both black. A washer with the Diesel log in satin finish aluminium decorates the electrical cable outlet on the base.
