When finding the difference between light measurements when fixtures are on and off, if the difference is above 20% but the footcandle measurement is below the Maximum Illumination Value for the type of lighting zone does it still comply? For example, if we were in LZ 4 where the maximum is .6 and we got a measurement of .3 with lights off and .4 with lights on (33% difference). Would it be acceptable if one of the requirements is met or does the compliance path have to follow one of the options?
