A combination for use in aligning a substantial point source of light with respect to an axis of a reflector is provided. The combination includes a reflector (82), a light source (3) having a substantial point source of light, and a movable light source holder (90). The movable holder may be moved using an actuating member. The reflector has a first open end (83) for emitting a light beam, a second end (85) and an axis (43) extending between the first and second reflector ends. The light source is secured to the movable holder and is disposed about the second end of the reflector. The actuating member is operatively coupled to the movable holder at an actuation interface for moving the substantial point source of light relative to the axis of the reflector and aligning the substantial point source of light with the reflector axis and the focal point of the reflector. Flashlights employing the combination are provided. |
