1. A multi-mode medical light source comprising:
(a) a first LED to provide light of a first light wavelength spectrum along a first light path;
(b) a second LED to provide light of a second light wavelength spectrum along a second light path;
(c) a dichroic filter for passing light emitted from at least one of the first LED and the second LED and reflecting light emitted from at least one of the first LED and the second LED;
(d) an optical filter movable between a first position in which the optical filter receives light from the first light path and a second position of which the optical filter does not receive light from the first light path;
(e) a light output;
(f) a controller which is capable of switching the light source between a first mode and a second mode, the first mode for providing a first imaging light to the light output and the second mode for providing a second imaging light to the light output.
