The difference between UVB and UVA is made by the difference in wavelengths and the energy in the photons of the light. UVA also has a longer wavelength than UVB does. Both of these wavelengths, however, are Ultraviolet, hence the UV. UV bulbs provide both UVA and UVB.
Sunlight contains two forms of radiant energy, ultraviolet A (UVA) and ultraviolet B (UVB). UVB provides the energy your skin needs to make vitamin D, but that energy can burn the skin and increase the cell damage that leads to cancer. UVA also contributes to skin damage and premature aging.
UV light bulbs are commonly used to sterilize and disinfect food, water, and air. Ultraviolet light bulbs deliver short-wave UV rays between 100nm and 280nm on the ultraviolet spectrum that alter the DNA of bacteria and microorganisms, eliminating them and preventing them from spreading.
