Sure: as long as the metal conductors and ceramic housing are
manufactured to that rating. Just remember: the _adapter_
up to a 600W load; the _floor lamp_
itself probably cannot.

My guess is the center contact of the original socket of the floor
lamp isn't sticking up far enough to contact the adapter. As you are
having problems getting the adapter out if would first make sure the
center conductor of the adapter is sticking up far enough. With the
lamp unplugged take a small flat-blade screwdriver to pry the flat
contact up a bit.
If you have or can borrow a volt-ohm meter unplug the lamp, set the
VOM to "ohms" (have your friend show you how) and test for continuity.
Connect one of the test leads to the one of the plug's prongs (yes,
the thing normally plugged in to the wall). The other test lead goes
to the socket under test. You have a roughly 50-50 chance of which
plug prong goes where in the socket. It will either connect to the
outside (screw part) or the center prong. If the tested plug prong
goes to the screw part move that lead to the other prong.
If the plug prong and center conductor are continuous then the problem
is the center conductor needs to be pryed up slightly so it contacts
the base of the bulb. (We're assuming the other plug prong and the
screw-part of the socket are also a continuous circuit.)
