Unlike his earlier bent aluminum lamps, Serge Mouille’s later lights are highly conceptual. Mouille built columnar metal cages around fluorescent tubes in order to emphasize the verticality of the bulbs, as well as to manipulate the neon glow emitted from the industrial lights. For the "Grand Totem" floor lamp Mouille took advantage of newly-available colored fluorescent bulbs, echoing the work of his contemporary, Dan Flavin.
