A suspension lamp includes a switch box, and a wire connection base. The wire connection base includes a main body, a plurality of elastic locking members, a first conductive plate, and a second conductive plate. Thus, the first and second connecting terminals of the power supply wire are inserted into the first and second insertion slots of the main body respectively, and the first and second connecting terminals of each of the electric wires are inserted into the first and second insertion slots of the main body respectively so as to form an electrical connection state, so that the electric circuit of the suspension lamp is connected easily and conveniently, thereby facilitating the operator mounting the suspension lamp.
