LED plant spectral lamp, have reliable meat Mody

Answer:

The wavelength of UVA band is 320 ~ 420nm, and the wavelength of UVB band is 275 ~ 320nm. The lights are generally made of UVB lighting, fluorescent powder through a blocking UVB band wavelength glass and a layer of the external wall of the lamp tube does not reach the UVA band.
Don't search for "light" lights, there are two kinds of common UVA, UVB, UVC short wavelength, the surface does not exist, nothing of value for.
