We have 4 recessed lights in our den which were installed by the original builder. At the time, he put in small floodlamps which always looked too small for the fixture. I had seen similar fixtures with larger diameter floodlamps so I purchased 4 new bulbs. The diameter of the larger floodlamps fits the fixture, but I noticed that none of the 4 bulbs is 'flush' with the ceiling. 3 are acceptable, but 1 seems lower than the other and doesn't look right. All 4 appear screwed in as far as they can go.

Is there a way to adjust how deep the bulb sits within the fixture? There seems to be room, but I can't tell from looking at it. Thanks!

 

You may have to remove the trim to look up inside the housing. Some have a depth adjustment for the socket.
