Abstract: A smart lighting device may be configured to be controlled in response to control instructions in messages and/or phase-control signals. The smart lighting device may determine whether to respond to the phase-control signal or the control instructions in messages. The smart lighting device may be configured to recognize whether it is electrically connected to a smart load control device or a non-smart load control device. A load control device may determine whether it is electrically connected to a mixed circuit or a non-mixed circuit. When the load control device determines that the circuit is a mixed circuit, the load control device may transmit phase-control signals and control instructions in messages at the same time. The load control device may determine that a smart lighting device has been added (e.g., electrically connected) to the circuit it is electrically connected to.

Abstract: Aromatic diketones are prepared by a process comprising contacting at least one acylatable aromatic compound and at least one aromatic diacyl halide in the presence of catalytic amounts of ferric chloride or ferric oxide at an elevated temperature and at superatmospheric conditions.
