Ac or dc

1:  Do you know the DC voltage of this if you add a bridge rectifier.  
2:  Will you still be able to use the same incandescent light bulb rated at ac voltages for the DC circuit.?

Yes you can use the same light bulb if you don't add a filter capacitor to the output of the diode bridge.

Dc voltage depenend on capacitor but will around 125v and of course you can use the same light but it will heat up little as in dc no interval of 60hz will be there

SkeLe your right only the ground references change from the middle of the sine wave to the bottom of the voltage & the bulb can't tell Ac or DC. paps, by changing the ground reference the voltage changes by around double. Give it a try.
