Total height of the lamp is adjustable, length of the cable alone is 100cm and can be shortened to your preference (if you need a longer cable we will rewire it for you free of charge, simple white one). Takes one e27 light bulb (not included). A standard e26 american/canadian size also fits (tested). Works with 220v as well as 110v. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I 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.
