A light and fragrance producing device includes an electrically powered light source and a separate electrically powered heating element. The device also includes a fragrance disk that can emit fragrances when heated by the heating element. The fragrance disk also can be configured to remain solid while heated by the heating element rather than melting or evaporating. The device can also include a decorative outer housing that can be interchangeable.
