It is argued on the basis of the BCS theory that the zero-T penetration depth satisfies lambda(-2)(0) alpha sigma T-c (sigma is the normal state dc conductivity) not only in the extreme dirty limit xi(0)/l >> 1, but in a broad range of scattering parameters down to xi(0)/l similar to 1 (xi(0) is the zero-T BCS coherence length and l is the mean free path). Hence, the scaling lambda(-2)(0) alpha sigma T-c, sTc, suggested as a new universal property of superconductors [Dordevic, Basov, and Homes, Sci. Rep. 3, 1713 (2013)], finds a natural explanation within the BCS theory.
