Tosca is a successful balancing act! The angled back leg straightens where it intersects the other two matte-black painted metal legs and extends upward where it bends again to secure a standard 100 Watt incandescent or 26 watt CFL bulb (not included) horizontally underneath the black fabric shade. The horizontal bulb allows the shade to be positioned off-center of the pole, creating a dynamic visual. It is operated by a black cylinder on a pull-chain switch. Overall depth at the base of the legs is 25" (9" back leg, 20" front legs).
