A narrow angle LED illuminated spotlight in which the light-emitting output of an LED light source is coupled with an optic element, in the form of a focusing reflector or focusing lens, and a masking element is interposed between the light source and the optic element to partially mask off the output area of the light source and significantly reduce the area of the emitted light reaching the optic element. This enables the light passed by the masking element to be concentrated into a, narrow beam (i.e., 18.degree. or less) using an optic element of much smaller size than otherwise, thus making the use of an LED light source module a practical source of light for narrow beam spotlights.
