Abstract
A lighting module includes a light output window, at least one side wall that defines a cavity and a mounting plate, and at least one light source, and at least one reflector that is within the cavity. The light output window may be one of the side walls in a side-emitting configuration. The spectral distribution of the light coming out of the light output window may be changed by manipulating the relative position of the side wall to the at least one reflector that is within the cavity.
