Abstract: A portable lighting device (100) comprising: at least one light source (106) arranged to emit light to illuminate an environment of the portable lighting device (100); at least one sensor (108), each of the at least one sensor (108) arranged to provide a sensor output signal; and a control module (110) arranged to receive the sensor output signal from each of the at least one sensor (108), wherein the control module (110) is configured to: detect user manipulation of the portable lighting device (100) relative to a support surface (200) on which the portable lighting device (100) is supported based on one or more of the at least one sensor output signal; and control the light emitted from the at least one light source (106) based on the detected user manipulation.

Abstract: A configurable controller for a lighting arrangement or assembly is adapted to control or change an output characteristic of the lighting arrangement in response to a user input received at a user interface. The configurable controller limits the amount to which a user input at the user interface may adjust the output characteristics by storing a range of selectable or presently available values for the output characteristic. This range of selectable values is adjustable based upon a configuration input received from a remote device at a communication unit.
