Method and system for illuminating a selected body component with light to encourage selected beneficial reactions of the body component as a result of such exposure and to provide phototherapy. Light is provided using a light delivery module (41) having one or more components (45) that fit around a body component (43), or are located at a particular site on or adjacent the body, where each light delivery component can be independently controlled. The body component is exposed to light in a first wavelength range and to light within a second wavelength range, in a first time interval and in a second time interval, respectively, that are separated by a selected dark field time interval where substantially no light exposure occurs, except for ambient lighting. The first and second wavelength ranges may be the same, may partly overlap, or may be mutually exclusive and preferably lie within the combined visible and infrared ranges.
