I’m in the process of buying my first house and when measuring up we noticed that there are some brown marks above the light fittings in the downstairs rooms. The marks seem to be directly above the bulbs (and not just around the fittings) which suggests to me that it’s some kind of burning from the heat of the bulbs and not an electrical fault in the fitting.
The previous owners were smokers and smoked inside the property – could it be the smoke that was heated by the lights staining the ceiling?

We are planning to paint all walls and ceilings – will covering them like that be enough? Will not smoking in the house and changing to LED bulbs prevent the issue from reappearing?
