Abstract: Example phototherapy systems, methods of using a phototherapy system, and methods of manufacturing a phototherapy system are described. An example phototherapy system includes a handle and a phototherapy light source. The phototherapy light source is attached to the handle, adapted to emit a light in a therapeutic wavelength, and includes a plasma lamp. The plasma lamp can be disposed between sheets of transparent material, including quartz. The phototherapy light source can be adapted to emit a light in a UVB wavelength between about 300 nanometers and about 320 nanometers and can have an output of between about 15 mW/cm2 and about 21 mW/cm2.
