1. A multi-mode portable electronic lighting device, comprising:

  • a housing including a source of power;

    a light source electrically connected to the source of power which emanates light away from the housing toward a plane along a principal axis of projection that is perpendicular to the plane at a point of intersection with the plane when an on/off switch is not in an off state;

    a controller configured to implement a plurality of modes of operation of the light source along the principal axis of projection when the on/off switch is not in the off state and a momentary switch is actuated; and

    a user interface for inputting commands to the controller,wherein the user interface comprises a motion sensitive interface in which commands are input through a first predefined movement of the portable electronic lighting device;

    wherein the controller will not change operation of the light source between the plurality of modes of operation when the on/off switch is not in the off state and the momentary switch is not actuated;

    wherein the controller is configured to change a mode of operation of the light source when the controller determines that the multi-mode portable electronic lighting device has been moved in the first predefined movement, so that the light source operates in a changed mode of operation; and

    wherein the controller is further configured to adjust light output of a given mode of operation of the light source when the controller determines that the multi-mode portable electronic lighting device has been moved in a second predefined movement when the on/off switch is not in the off state and the momentary switch is not actuated.
