Total height of the lamp is adjustable, length of the cable alone is 140cm and can be shortened to your preference. Takes one e27 light bulb (not included). A standard e26 american/canadian size also fits (tested). Works with 220v as well as 110v. we believe a bigger milky white bulb is the best fit for this lamp (bulb in the photos), you can however use whatever bulb with e27 screw (for size perception, the milky white one is 9,5cm diameter compared to standard 6cm diameter). This piece has an attribution mark, i am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution, up to 250v (europe/uk standard).the wiring of this item may be original and might need replacement, if not specified otherwise.
