An electrodeless fluorescent lamp having an emission suppression arrangement utilizing a capacitive filtering element formed by a first conductive layer disposed on a portion of the interior surface of the lamp envelope, a second conductive layer on a corresponding external portion of the lamp envelope and the glass material of the lamp envelope disposed therebetween, achieves significant emission reduction yet at the same time reduces eddy current losses otherwise occurring at the second conductive coating portion of the capacitive filtering element. A plurality of slots formed in the second conductive coating are effective so as to reduce the circular flow of eddy currents around the second conductive layer, such eddy currents as would otherwise adversely affect the Q of the circuit.
