We've covered the covetable modernist style of the Lampe Gras 205 lamp before: The Lampe Gras 201 has that same sense of utilitarian style.
Designed by Bernard Albin-Gras back in 1921, this model clamps onto a desk or a shelf to provide maximum light where needed. Indeed, you can imagine Le Corbusier using it as he poured over his plans and drawings. It comes in a variety of finishes: take your pick from black and chrome, black satin or satin red and black.
The lamp costs £328.
