Does anyone know if there is a web site that gives a clear, to the point, explanation of the numerous codes that regulate the support of lighting fixtures in suspended ceilings. I have read the posts on a number of forums and Googled the codes (IBC, ASCE 7, CISCA, ASTM C-636) but it just goes in a circle. One code will specify that you have to meet the requirements of another. Is there chart or table somewhere that spells out if you have this set of circumstances then you must do it this way?
