The lamp offers a fully articulating arm with a 32"-reach that easily locks into any desired position using the fold-down clamp handles on the upright. Secure the lamp to your bench or work surface in either of two ways: screw it permanently to the surface (hardware is not included) or use the mounting clamp (included; 1-1/2" max. opening) to attach it at the edge of your bench or table. The lamp body is constructed of lightweight aluminum with an easy-on-the-eye, non-reflective matte finish. Power cord is a full 6 feet long; ideal for positioning lamp as needed.
