1. A light source for examination of a substance which emits light at a wavelength greater than a wavelength of light emitted from the light source when the substance is excited by the wavelength of light emitted from the light source, the light source comprising:
- a housing having a light outlet; and
a low-voltage lamp positioned in the housing and oriented to emit light through the light outlet comprising a light emitting diode, wherein the low voltage lamp emits light of a wavelength within a predetermined range of less than about 500 nm.
