Abstract
A high-pressure discharge lamp has integrated in its base or base housing a circuit arrangement (SCH) which combines a starting device and a power reducing circuit which comprises a phase-gating control (PS). A capacitor (C,) connected in parallel with the lamp (L) provides a transfer voltage which is distinctly higher than the input voltage of the arrangement.
