A light reflector for use in a lighting device including a light bulb having a filament. The reflector includes a cup-shaped body having a parabolic internal reflective surface divided transversely into an inner portion surrounding the light bulb to focus light from the light bulb into a parallel light beam to produce a bright spot and an outer portion adjoining the inner portion. The outer portion is faceted to smooth blurring around the bright spot.
