In an extended Higgs sector, the charged Higgs could still be somewhat lighter than the t-quark. Taking the NMSSM as a specific framework, we show first that H+ cannot only decay into fermion final states but also in W+ and a light Higgs, which is mainly gauge singlet like. The latter can further decay into two photons. We will discuss the possibility and the challenges to discover H+ via the cascade t -> H+ b -> gamma gamma W b at the LHC.
