- sametmax 8y agoOf course, but sunlight is not just UVB. Plus, the spectrum of one component is hardly what define light interraction. The many spectrums + quantity + intensity + the human receiving is a more interesting model. E.G: I just bought a light to help with the winter blues. It does not provide any UVB, so the method of action is something else.
