An antibiotic product is comprised of at least three dosages forms, each of which has a different release profile, with the Cmax for the antibiotic product being reached in less than about twelve hours. In another aspect of the present invention, the slave light emissions are controlled in such a manner that a flash time ratio between master and slave flash lights during pre-flash is caused to be approximately equal to a flash time ratio between master and slave flash lights during main flash. In one embodiment, the relative movement is accommodated by a spherical actuator head rotating in a compressively spring-biased socket. Communication can occur between each of the proximate end-user devices and the remote devices in accordance with the flow-specific quality of service attributes. The invention also relates to a device for managing the supply to a discharge lamp.
