The circuit consists of a 20-kHz oscillator, a switching transistor to amplify its output, and a step up transformer. A 120- to 6-V power transformer is connected backward, using half of the 12-V side for 6 V. In the circuit, the transformer is working at considerably more than its rated voltage, but the high frequency keeps it from saturating. Although the lamp does not glow at full brightness, the circuit is energy-efficient, requiring only 150 mA.
