Summary:A monitor device is provided for monitoring a lighting arrangement of lighting elements of unknown electrical load, and a driver using the monitoring arrangement. A set of duty cycles is applied to switches which control sub-sets of lighting elements thereby to create a desired light output. With this desired duty cycle setting, the current for an individual duty cycle period is monitored, in particular to detect variations in a current plateau level 5 within the individual duty cycle period. This is used to determine a power consumption of the lighting arrangement and to adjust the duty cycles as a function of the detected current. This avoids the need to probe the sub-sets of lighting elements individually in order to determine the nature of the load and its power consumption.
