Adapter for retrofit lamp

    When a fluorescent lamp is recycled into a retrofit lamp, the retrofit lamp is often equipped with a somewhat shorter discharge vessel (than the opriginal lamp) and an adapter in the form of an additional impedance. The adapter generally comprises an inductor and causes the retrofit lamp to be wrongly connected to the ballast (a classic 50 Hz CuFe ballast) 50% of the time. This problem can be overcome by making use of an adapter comprising magnetically coupled inductors as shown in the figure. This adapter forms an extra impedance during operation of the lamp irrespective of its orientation with respect to the ballast.
