A1) Very little, other than it won't flicker at 50Hz.

A2) So that a clean-and-tight connection ensues. What else would one do - a tape-joint?

One half cycle will be missing in the DC out put, thereby the out put voltage will be half of AC input voltage.

Lumen output of the lamp will be reduced, not sure by how much. Yes, it will appear to be flickering.
