To simplify assembly of a bottom portion (4) with a cap portion (3) of a base to a compact fluorescent lamp, and permit automated assembly thereof, the cap portion is formed with inner axially extending projections (23-26), and current supply leads (27a-28b) are looped about the axially extending projections. A circuit board (8) located transversely across the bottom portion (4) has essentially U-shaped bow frames or arched or clip elements (35-38) located thereon which are positioned to engage by resilient surface contact with the end portions (31) of the current supply leads when the bottom portion and the cap portion are snapped together upon axial movement. Inwardly extending ribs (44, 45; 48, 49) projecting from the inner wall of the bottom portion support the bow frame or arched or clip elements, and ensure prestressed reliable contact engagement between the bow frame or arched or clip elements and the end portions of the current supply leads. Preferably, the end portions of the current supply leads and of the clip elements are made of tinned wires.
