Abstract
A dental lamp includes a control system adapted to control operation of a light source within the dental lamp. The control system requires that an unexpended light guide including a recordable medium be coupled to a lamp head of the dental lamp, in order to illuminate the light source. The control system records a first data signal on the recordable medium during illumination of the light source indicating that the light guide has been expended. The control system also records a second data signal onto a second recordable medium so that a particular duration of use of the light source may be indicated.
