New concepts of Lebesgue measure on $ℝ^{∞}$ are proposed and some of their realizations in the ZFC theory are given. Also, it is shown that Baker's both measures [1], [2], Mankiewicz and Preiss-Tišer generators [6] and the measure of [4] are not α-standard Lebesgue measures on $ℝ^{∞}$ for α = (1,1,...).
