Analyzing {upsilon}(nS) decays acquired with the CLEO detector operating at the CESR e{sup +}e{sup -} collider, we measure for the first time the product branching fractions B[{upsilon}(nS){yields}{gamma}{chi}{sub bJ}((n-1)P)]B[{chi}{sub bJ}(n-1)P){yields}X{sub i}] for n=2 and 3, where X{sub i} denotes, for each i, one of the 14 exclusive light-hadron final states for which we observe significant signals in both {chi}{sub bJ}(1P) and {chi}{sub bJ}(2P) decays. We also determine upper limits for the electric dipole (E1) transitions {upsilon}(3S){yields}{gamma}{chi}{sub bJ}(1P)
