Abstract

A device suppresses flicker and improves compatibility of a lamp including at least one solid state light source the lamp being operably connected to a control circuit such as a dimmer circuit. The device includes a connector enabling connection of the solid state light source to a lamp socket configured to receive an incandescent light source and an adapter circuit connected in parallel with the at least one solid state light source when the solid state light source is connected to the socket via the connector. The adapter circuit provides a resistive path for current to pass through the lamp during all or part of the AC mains cycle.
