Spectrum of a blue/green electroluminescent light source for a clock radio. Peak is at 492nm and FWHM spectral bandwidth is 85nm. Spectrum taken by me using an Ocean Optics HR2000 spectrometer [1] with a high-OH solarization-resistant fiber optic light guide. This spectrum is not calibrated for intensity.
