A wireless medical imaging system comprising a head unit and a light cable is provided. The head unit comprises a head unit case, a head unit electrical connector, an image sensor, a wireless transceiver, a central processing unit, and a user-input component. The light cable comprises a light cable electrical connector, a power cable, and an integrated light source. The integrated light source comprises an emissive radiation source having a first spectrum, an optical element located to direct emissions from the emissive radiation source, a volumetric spectrum converter, an optical reflector located about the converter, and an output filter. The converter converts emissions directed from the emissive radiation source to emissions having a second spectrum different from the first spectrum. The reflector reflects the converter emissions towards the output filter. The integrated light source transmits light from the light cable through the output filter.
