The house I just moved into has a tall (two story) front entrance
with a porch light suspended by a chain and hanging about 11ft off
the ground. It has three candelabra lights and two of them are
burnt out. My standard step ladder is too short and I have no way
to reach the fixture. The fixture is open at the bottom but only
about 5" in diameter and the bottom has a base that holds the light
sockets and looks as though it could swing freely within the overall
glass enclosure. Is there some trick to replacing the bulbs in these
fixtures?

I'd make one trip, that would be to replace the fixture with something more
practical. Candelabra lights are not known for their long life either.

A commercial grade architectural metal halide fixture comes to mind.
Will last a long time and be quite efficient as long as you can live
with the slow startup.
