Be very careful with the generallity of that premise. That is both a true statement and a false statement at the same time. Some characteristics of indoor and outdoor uv exposure are the same, such as the equivalence of the MED's received, and the ability to cause production of vitamin D.
But there are differnces too, such as the high amount of UVA from high pressure beds, the extension of the UVB wavelengths to ones shorter than 290 nm, in all tanning beds, the dropoff of UVB at about 290 nm from sunlight, the higher spectral ratio of Deff/Eeff weighted UV from some tanning lamps than solar UV (depending on the time of day, etc), the loweer spectral ratio of Deff/Eeff UV from othe tanning lamps than solar UV (same limitations), etc, etc, etc.
