ABSTRACT:
A flashlight that can be adjusted to provide different size light patterns at a predefined distance from the light is disclosed. The light patterns are always in-focus thereby providing well defined and uniformly illuminated areas of light. The focusing mechanism utilizes stationary lenses and a movable lens to adjust the diameter of the light pattern without allowing the pattern to become out of focus.
