The Grantham Arc Lamp has a heavily weighted base supporting a gently curved brushed steel arc. The modified drum-shaped natural linen fabric shade adjusts vertically to direct light where needed. This modern arc lamp is conveniently operated by an on/off foot step switch. Grantham Arc Lamps provide excellent room light from a single 150 watt incandescent or equivalent CFL bulb (not included). The overall lamp depth adjusts from 53.5" to 60", the base measures 12.5" in diameter, there is 61.5" of clearance from the floor to the shade bottom and the shade tapers from 15" in diameter at the bottom to 13.25" at the top. It has a clear 60" long power cord and is smart outlet compatible.
