The lamp is provided with an upper hollow-cylindrical glass portion, and a base which has a bottom portion in the form of a flat plug. A separating wall extends parallel to the axis of the lamp and has bores on both sides of the wall. Connecting wires are inserted in the bores and extend into the upper hollow-cylindrical glass portions. The bores and connecting wires are substantially at the center of the bottom portion of the base, and grooves communicating with the bores, provides access to them.
