This piece is based around a cast iron industrial/mechanical part. Heavy Cast Iron, Simple, Industrial. This is considered a larger version of our Cast Iron Industrial Lamps – Dark Blue / Black and Beige cloth covered cord. The cast iron acts as the touch control for the lamp to easily turn on/off/dim (3 levels of brightness). The base is handcrafted out of solid wood with measurements of 6.5 inches x 6.5 inches. A porcelain socket and cloth covered reproduction cord adds a nice finishing touch to the piece. Edison style filament bulb is included.
