A fiber optic light guide luminaire includes an elongated fiber optic light guide having a first end accepting light from a remote source of illumination and a second end emitting light on an optical axis disposed coaxially near the focus of a paraboloidal reflector. The paraboloidal reflector has a first end wherein the light guide is disposed and a second open end emitting light from the fiber optic light guide. The second end of the light guide extends into the first end of the reflector towards the second end of the reflector and past the focus of the paraboloid at a distance approximately equal to the diameter of the light guide, whereat the diameter of the second end of the light guide intersects the paraboloidal surface of the reflector at an angle of approximately 20 DEG to the optical axis. In a preferred embodiment the exterior of the luminaire is generally cylindrical and externally threaded.
