The selected LDC-class influences the room utilization factor: as wider the distribution, as darker the room and as lower the direct part as lower the room utilization factor; this means that more light has to be installed to reach the required illuminance. endobj Si, Wire Insulation 3. Table of Contents 1. The reflectance factor table in the system helps you determine the reflectance factors. Utilization Factor (body of the table) This is a value between 0 and 1 that represents the percentage of total lamp lumens in the room that fall on the work plane.
