Selling my shiny white Flos Spun Floor Lamp, which retails for $1,695 (https://usa.flos.com/modern-floor-lamps/Spun-Light-F). The base diameter is 19.5", as is the shade's. The height is 69.5". There are a couple of small nicks on the base, hardly noticeable. The new bulb works perfectly with the floor dimmer switch--no buzzing noise. Flos stamp on the bottom of the lamp. Pick-up in upper Manhattan in an elevator building.
From usa.flos.com: "Designed by Sebastian Wrong in 2003, the Spun Light-F floor lamp reflects the best of modern manufacturing technology combined with elegance, craftsmanship, and dynamic fluid aesthetics. Its main body has a spun metal frame and diffuser. The diffuser support arms and lamp-holder support are die-cast aluminum, and the diffuser supports are white, injection-molded PC (polycarbonate). The dimmer has a 0-100% luminosity adjustment on the polarized cord."
