I am trying to fade the dye in fabrics with common UV lights, like that of tanning bed bulbs. There are options with amounts of both UVA and UVB. I am after a result with the highest degradation. Is UV degradation and Phototendering to dyes mainly from UVA or UVB? Would the level of degradation be higher faster with more UVA or UVB?
Not really talking about what would be 'dagerous', besides UVB creates cancer so I would have thought that much more dangerous then UVA...
PA is protection grade of UVA... The more + in PA has... The greater it protection against UVA...

Long-term use of uva ursi is not recommended as hydroquinone (produced in the body in response to uva ursi) is poisonous in large amounts. Practitioners recommend that it be taken for no more than two weeks at a time.

Sun tanning beds primarily use ultraviolet (UV) radiation, specifically UVA and UVB waves. UVA rays penetrate the skin more deeply and are responsible for skin aging and tanning, while UVB rays are more intense and contribute to sunburn and the skin's production of vitamin D. Tanning beds typically emit a higher proportion of UVA rays to produce a tan more quickly, but this also increases the risk of skin damage and cancer. It’s important to use tanning beds cautiously and consider the associated health risks.
Yes, UVA rays are more prevalent than UVB rays in sunlight. UVB rays are more intense but make up a smaller portion of the UV radiation that reaches the Earth's surface.
