1. A dimmer switch for controlling the amount of power delivered from a power source to a lighting load, the dimmer switch comprising:

  • a controllably conductive device adapted to be coupled in series electrical connection between the source and the lighting load for controlling the intensity of the lighting load;

    an intensity adjustment actuator operatively coupled to the controllably conductive device, such that the controllably conductive device is operable to adjust the intensity of the lighting load between a low-end intensity and a high-end intensity in response to actuations of the intensity adjustment actuator; and

    a visual indicator operable to be illuminated a first color when the intensity of the lighting load is less than or equal to a predetermined eco-level intensity, and a second color different than the first color when the intensity of the lighting load is greater than the predetermined eco-level intensity, the predetermined eco-level intensity being greater than 75% of a maximum possible intensity of the lighting load.
