Analyzing \ensuremathΥ(nS) decays acquired with the CLEO detector operating at the CESR e+e^\ensuremath- collider, we measure for the first time the product branching fractions B[\ensuremathΥ(nS)\ensuremath→\ensuremathγ\ensuremathχbJ((n\ensuremath-1)P)]B[\ensuremathχbJ(n\ensuremath-1)P)\ensuremath→Xi] for n=2 and 3, where Xi denotes, for each i, one of the 14 exclusive light-hadron final states for which we observe significant signals in both \ensuremathχbJ(1P) and \ensuremathχbJ(2P) decays. We also determine upper limits for the electric dipole (E1) transitions \ensuremathΥ(3S)\ensuremath→\ensuremathγ\ensuremathχbJ(1P).
