An electrically operated diffuser has a fragrance-emitting element (8) for facilitating diffusion of an active material, and at least one light emitting diode (7). The at least one light emitting diode (7) serves as a nightlight and has a luminous intensity rating of at least about 5000 mcd at 20 mA. Also, the at least one light emitting diode (7) may be positioned at a back surface of the diffuser, such that when an active material is received in the compartment the at least one light emitting diode (7) shines through the active material. The diffuser may include a remote-use assembly to supply power to the diffuser from a wall socket remote from the diffuser. The diffuser may also include a light controller to change one or more of the color and the intensity of the at least one light emitting diode (7).
