An illumination circuit includes a ballast, a capacitor, a first lamp and a second lamp. The capacitor and the second lamp constitute a first operative current path for igniting the second lamp by a coupling of the capacitor to a first node and a second node, and a coupling of the second lamp to the second node. A ballast, the first lamp and the second lamp constitute a second operative current path for igniting the first lamp by a coupling of the ballast to the first node, a coupling of the first lamp to the second node, and a series coupling of the ballast and the first lamp.
