The utility model discloses a compact fluorescent lamp which comprises two U-shaped or spiral lamp tubes, two independent electronic ballasts which are respectively connected with the lamp tubes to drive the lamp tubes to work normally, a printed circuit board on which all components of the two independent electronic ballasts are installed and a lamp holder connected with the parallel power input lines of the two independent electronic ballasts; the compact fluorescent lamp is characterized in that: only one printed circuit board is arranged, and all the components of the two independent electronic ballasts are divided into two parts and installed on the printed circuit board in a completely symmetrical manner along a symmetry axis. Compared with the prior art, the compact fluorescent lamp has the following benefits: the arrangement of all the components is intuitive and clear, the spacing is reasonable, and heat dissipation is uniform, thus being beneficial to producing plugins of large-power self-ballasting
