Embodiments of the present invention provide a system and method for filtering light from a light source (220). More particularly, embodiments of the present invention may filter direct and reflected light provided from the light source to a source of illumination (212) by using one or more mirrors (230a,230b) in an optical path. In a specific embodiment, one or more cold mirrors (250) in the optical path are coated such that they are operable to reflect light in the desired wavelengths while transmitting other wavelengths of light. Thus, as light from a light source is reflected off these cold mirrors undesired wavelengths of light may be substantially removed from the light before it is utilized to illuminate an area. In other embodiments, one or more hot mirrors (260) may also be provided in the optical path, where these hot mirrors are coated such that they are operable to transmit the desired wavelengths of light and reflect undesired wavelengths.
