there are no separate grounds in everycircuit. Wherever You place gnd it refers to the same gnd. Make one common gnd on trasformer both ends. Connect voltometer to bulb - it will measure voltage on both bulb ends (not referenced to theground). Finally lower transformer primary inctance to about 500 uH. I got 24.6 V on bulb - transformers have some power lost on them

No matter what basic power supply you make there will always be ripple, what you have to do is to have a reference so the amount of real ripple is evident, you can do as suggested by Dario1985 and put a meter across the load or you ca can just put a dummy resistor somewhere in the circuit and tag it as in my sample. http://everycircuit.com/circuit/5176181065515008
