I installed five incandescent, recessed light fixtures in the cathedral ceiling of my living room. The fixtures are wired in
parallel series (A connects to B connects to C ...). All the wiring is done correctly.
However, the fixtures are burning out bulbs very quickly. More quickly than normal, in my experience. Some of the bulbs were expensive LED bulbs and the rest were incandescent floods.
What should I check? I really don't want to open and recheck every fixture, even though they are easily accessible from the attic. I need some idea of what to look for.
