Abstract
A replacement device for a light bulb includes a translucent shell and a base. The base supports a plurality of colored lights positioned so as to emit a light show through the shell. The base is configured to be received in a conventional light socket. The base also includes a compartment for receiving and securing a replaceable volatile active cartridge for enabling the device to emit an active ingredient from the cartridge when the cartridge is secured in the compartment. A dimmable white light source may also provided in the shell as a source of illumination. Thus, a single device is used as a replacement for a conventional light bulb and is a combination white light source/colored light show source/volatile active source.
