UV light begins at 400 nanometers and above (smaller wavelength number = faster wavelength and more dangerous). Blue light is very intense and just inside our visible spectrum. This chart shows how LED, CFL & Fluorescent sources deliver a heavy dose of blue light.
This chart illustrates how blue light rich LED light sources are nearly identical to our Circadian Rhythm sensitivity. This means that excess blue light during the evening hours can make it difficult to fall asleep, and in some cases have a very negative affect on sleep cycles.
