If you have a laser thermometer, replace the bulb, put on the cover, and turn on the light for a minute or so. Then remove the cover (light is still on) and take the temperature of the fixture in various locations starting with the plastic light bulb base. As I recall, I had some very high numbers, close to 200 degrees. Do a comparison with a few other fixtures.
Can you post a picture of the fixture??
No, TT is in storage now, but it is just your basic 2 light ceiling fixture with a bulb and a lens on both sides and an on off switch in the middle. The bulb blackening and the socket browning only happened on one side.
