Does anyone know which NEC article restricts us from installing lighting above a hung ceiling, if at all? I've seen some crazy stuff out there, and came across something new I have never seen. Without the details, the fixture was installed in violation of it's listing, but I wanted further clarification as to weather or not the fixture could even be in a location like above a hung ceiling, which it is. It's a 2x2 lay-in for grid ceilings screwed to the structure above, with the lens removed and it's bottom edge sit about 6" above the ceiling line, and an acrylic lens is installed into the grid space just below. Not good. I am thinking of recommending the fixture be changed to a single lamp strip fixture, but thought this was also a violation as it would be above the ceiling.
