Abstract
A medical headlamp having a front from which light is selectively emitted. The headlamp includes a beam origination portion that produces a light beam and an iris assembly, positioned in front of the beam origination portion, having a user accessible actuator and an iris, responsive to the actuator to block a user-selectable portion of the light beam. The iris is also responsive to the actuator to block none of the light beam, for maximum efficiency, when a user so selects.
