level. I have given you the details for Point by Point
Method for calculating the LUX requirement

LUX = (CANDELA x COS(a) x F) / D^2

Where Candela = Luminous Intensity (cd/1000lumens)
COS(a) = Required Luminous Intensity at an Angle of
(a)
D = Mounting Distance of luminairy in meters
F = Maintenance Factor
This method is generally used for Outdoor Lighting purposes
