Abstract: A luminaire has a light-emitting diode (LED) light source, a light sensor, and a control system. The control system receives a Measure command measure the current intensity of the LED light source. The control system measures the intensity using the light sensor, stores current intensity data in non-volatile memory, obtains the LED light source's previous intensity, selects an indicator color representing how much the current intensity is reduced from the previous intensity, and causes the luminaire to emit a light beam having the indicator color. The control system also receives an Adjust command to reduce the LED light source to a total intensity reduction amount. The control system obtains the LED light source's current reduction amount, determines whether the total intensity reduction amount is more than the current reduction amount, and, if so, causes the LED light source to emit a reduced intensity light beam.

The motion assembly includes a motor, a magnet mounted directly to a shaft of the motor, and a motion sensor system. The motor rotates the mirror about an axis of rotation.

The motion sensor system produces an output signal representing an absolute rotational position of the magnet. The control system stores an expected rotational position of the motor and determines whether the motion sensor system's output signal matches the stored position. When the output signal does not match the stored position, the control system rotates the motor position where the output signal matches the stored position.
