5A light meter for detecting two or more different wavelengths of light and methods for determining whether a light source configure to emit light at two or more dominant wavelengths is working properly. The inventive light meter includes a housing, two or more receiving means for receiving light energy emitted by an external light source wherein each receiving means is configured to receive light energy of a desired wavelength, detecting means for detecting and measuring light energy received by the receiving means, and display means for providing a visual indication of the existence and intensity of one or more wavelengths of light energy received by the receiving means.
