An adapter device for a lamp or light fixture includes a male connector, a female socket and control circuitry. The adapter supports at least one RGB LED cluster positioned so as to emit a colored light show. The male connector is configured to be received in a conventional light socket. The adapter also includes a slot for receiving and securing a replaceable volatile active insert for enabling the device to emit an active ingredient from the insert when the insert is secured in the slot. A conventional light bulb or a CFL may also be connected to the female socket as a source of illumination. Thus, a single adapter is used to combine a conventional light source/colored light show source/volatile active source.
