ABSTRACT:
A multi-lens luminaire has a generally cylindrical tubular macro housing including a plurality of generally tubular micro housings disposed within the macro housing and angularly spaced about the axis of the macro housing. Each micro housing has a proximal end adjustably retaining a fiber optic light guide emitting light from a remote source of illumination. The light guide is movable along the optical axis of a lens in the distal end of the micro housing, whereby the resulting light beam is capable of zoom adjustment. In a preferred embodiment the macro housing is externally flanged and has a threaded portion adapted for engaging a nut to secure the macro housing in a mounting panel.
