We study the electroweak phase transition by lattice simulations of an effective 3-dimensional theory, for a Higgs mass of about 35GeV. In the broken symmetry phase our results on masses and the Higgs condensate are consistent with 2-loop perturbative results. However, we find a non-perturbative lowering of the transition temperature, similar to the one previously found at mH=80GeV. For the symmetric phase, bound state masses and the static force are determined and compared with results for pure SU(2) theory.
