We use (111±1) million Υ(3S) and (89±1) million Υ(2S) events recorded by the BABAR detector at the PEP-II B-factory at SLAC to perform a study of radiative transitions between bottomonium states using photons that have been converted to e[superscript +]e[superscript -] pairs by the detector material. We observe Υ(3S)→γ[subscript χb0,2](1P) decay, make precise measurements of the branching fractions for χ[subscript b1,2](1P,2P)→γΥ(1S) and χ[subscript b1,2](2P)→γΥ(2S) decays, and search for radiative decay to the η[subscript b](1S) and η[subscript b](2S) states.
