An electrodeless compact fluorescent lamp (ECFL) operated at RF frequency of 2.65 MHz has been used for several years to replace R-type incandescent lamps [I]. Unfortunately, this ECFL has relatively low light output (1100 Lm) and does not fit many fixtures due to its size (130 mmx 80 mm) that is larger than the size of aregular incandescent lamp (120 mm x 60 mm). In this paper we present design and characteristics of a long life ECFL which is of the same size as an incandescent lamp and delivers 1500 lumens while operating at lower frequencies (80 - 400 kHz vs 2.65 MHz of the former one) with its inherent lower cost and higher driver efficiency (>90% vs <85% of the former one).
