There's Water In There?
Yes, water from a source above the room or area affected by the water damage can accumulate in the light fixture.
This fixture involved in a Whitney, TX, area tornado and thunderstorm fill up so much with water, it became dim....and warm. The bulb was heating the water.
Water can get into a light fixture traveling along wires in the ceiling or attic. It can also just soak straight though the drywall, etc., right into the globe and hold the water. Turns out light globes will hold water.
Water will also run along electric lines in the ceiling or attic and drop off at low points or obstacles. This can produce water spots in the ceiling well away from the main affected areas. Usually the amount of water traveling the line is small, but problematic.
Normally, the water won't have any real affect on the electricity itself.
