My experience with CF bulbs is they do not always screw in as tightly or
completely as regular bulbs for whatever reason. I would first assume
that the bulb is not making solid contact with socket. Grab the porcelain
base of the bulb and turn a bit tighter. Grabbing by bulb glass is unwise
since the bulbs do break readily.
