A lighting system includes a group of light emitting diode (LED) illumination devices, each of which includes a device driver. One or more sensors are configured to measure a characteristic of light received from the devices in an area of an environment that is illuminated by the devices. A controller detects when a value of the measured light characteristic received by a sensor deviates from a desired value.
