That all depends on where the transfomer is. If its internal(like with Spiral CFL's), You could wire it directly to 120V by pulling out both leads. I've done this with spiral CFL's many times, And with those it doesnt seem to matter -or+. I've conected them both ways.
BUT and this is a big BUT, If the transformer components reside in the socket or fixture(like the 4' tubes and such) portion then the answer is no.
