The Dankov Floor Lamp in Satin Steel has an outer shade made from unique smoked mercury glass with a brushed steel central pole and base. It can be used with or without an included inner bowl-shaped shade made from white acrylic producing great ambient light. Use with edison-style vintage light bulbs without the inner shade for a unique look. A three-way rotary socket switch operates a 150 watt incandescent or three-way equivalent CFL bulb (not included). This clean-lined contemporary floor lamp has a single metal pole and flat 11" diameter base.
