I just compared these two fenix lights with new/ fully charged batteries and the RC10 wins big. Both have the same halo or wide angle coverage but the rc10 will throw much farther.
RC10. PD32 S2 is nice, but I would get the RC10 too. a friend at work has the RC10 and pd32UE, and RC10 he always has more than the PD and uses for throw.
