Specifies the number of and type of lights needed to provide uniform illumination for the entire space. This value is calculated by determining the total light loss factor, which is then used to calculate the number of lights, as shown in the equations below.
Total Light Loss Factor = CU x LLD x LDD
Where:
CU = Coefficient of Utilization
LLD = Lamp Lumens Depreciation
LDD = Lamp Dirt Depreciation
And
The equations above are used for all lighting zones except Street Light. The following
equation is used to determine the number of street lights.
