Abstract
An apparatus including a theater lighting device including a lamp housing; a base housing; and an internal spectral sensor. The lamp housing is rotationally mounted to the base housing; and includes a plurality of light sources, and lenses which cooperate to project a final output light; wherein residual light is received by the internal spectral sensor from internal reflections of a first lens of the plurality of lenses and the residual light is converted to spectral data. The spectral sensor is a multispectral filter array type. The theater lighting device further includes a microprocessor; and a memory, wherein the memory stores a first set of data for a plurality of electronically adjustable parameters of the theater lighting device. The microprocessor is programmed to receive a first command and in response put the theater lighting device in a first state.
