Abstract

A lighting apparatus is provided including a main reflector member having a primary axis and an inner reflective surface for reflecting light to an area to be illuminated; a supplemental reflector member which also serves as a socket cover, smaller than the inner surface of the main reflector member, removably attached with respect to the inner surface of the main reflector member; and a light source configured and arranged such that a portion of the light emitted from the source will be reflected by the supplemental reflector member to the inner reflective surface of the main reflector member for reflection to an area to be illuminated.
