A roof mounted light well oriented to maximize the collection and transport efficiency of solar radiation through an aperture into a building. The device includes a structure having side walls and an upper surface. A light well is located within said structure, and may be partially comprised of said structure. The light well defines a light passageway. The light well is oriented to maximize pass-through of average annualized solar light through said light well. In one embodiment, the light well extends below the roof of the building to a ceiling structure within the building. In some instances, one or both of an upper surface and a lower surface of the light well is horizontal. A reflective element may be provided that projects upwards from the structure. The reflective element may be retractable.
