Abstract: A method is for dynamically adjusting a circadian rhythm of an observer via a user device that includes control circuitry and an associated memory. The method includes determining a preconditioning schedule for at least one future event. Determining the schedule includes determining a preconditioning schedule for the at least one future events, including identifying a circadian shift needed, to the circadian rhythm of the observer, for the at least one future event, determining a timeframe for preconditioning, determining a per-day shift needed based upon the identified circadian shift needed and the determined timeframe, and determining if the needed per-day shift exceeds a threshold. Upon a determination that the per-day shift exceeds the threshold, the method includes setting the preconditioning schedule responsive to the determination to operate a light source to emit light based upon the preconditioning schedule.

Abstract: A lighting device may include a light source, a control circuit, and a communication device positioned in communication with the control circuit. The communication device may be configured to receive a transmission from a user device, and the transmission may include a data structure. The data structure may include a show packet and an event packet. The show packet may include an ID string and information regarding a number of event packets associated with the data structure, and the event packet may include information regarding a lighting spectrum, a fade type, a fade duration, and a hold duration. The control circuit may be configured to operate the light source to emit light transitioning from a present light emission having a present spectral power distribution to a light emission having spectral power distribution indicated by the lighting spectrum according to the fade type and fade duration.
