  We carry out a comprehensive investigation on the radiative decays of
$P$-wave bottom baryons using the light-cone sum rule method. We analyze their
electromagnetic transitions into ground-state bottom baryons together with a
photon. Together with their mass spectra and strong decays investigated in
Refs. \cite{Yang:2020zrh,Tan:2023opd}, a rather complete QCD sum rule study has
been done to understand the $P$-wave singly bottom baryons within the framework
of heavy quark effective theory. As summarized in
Tables~\ref{tab:candidate}/\ref{tab:candidate6f}, some $P$-wave bottom baryons
have limited strong decay widths so that their radiative decay widths become
non-negligible. We propose to study these excited bottom baryons and their
radiative decays in the future Belle-II, BESIII, and LHCb experiments.
