Abstract: A compact, high-intensity light assembly including a substantially hollow shell having a distal end from which the light emerges and a proximal end into which a base unit inserts. A lamp guide holds the light source in a central position within the shell using a spring which urges a rear portion of the lamp guide against an annular seating lip on the base unit. The lamp guide preferably includes a necked-down portion having an inner surface which makes holding contact with the outer surface of the light source, and an outer surface including heat-radiating features. In a preferred embodiment, the base unit is insertable into the proximal end of the shell by way of a threaded connection, enabling the lamp guide and light source to be adjustably moved relative to the distal end of the shell so as to focus the light from the source into a preferred illumination area.
