George, I have found it easier to say the "least" dimension has to be wider than 4ft. No coverage would be required below the lights in this case. Dewayne Martinez Design Build Fire Protection New Berlin, WI

According to NFPA-13 (2007) Sec. 8.6.5.3.3 it seems I need Coverage under a 4' wide fixed obstruction. My sprinklers are 5' above the lights. Do they need to have ceiling tiles in place around it or is there a solution I am missing. Any help would be greatly appreciated.
