M. Hennings and G. Kuperberg defined quantum invariants $Z_{\rm Henn}$ and $Z_{\rm Kup}$ of closed oriented 3-manifolds based on certain Hopf algebras, respectively. We prove that $|Z_{\rm Kup}|=|Z_{\rm Henn}|^2$ for lens spaces when both invariants are based on factorizable finite dimensional ribbon Hopf algebras.

Keywords: Knots, 3-manifolds, Hopf algebras, TQFT
