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.
