There are many ways for calculation of LUX and Illumination
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

I need to compare the energy consumption of an industrial machine before and after improving. Shall I compare the apparent power or the active power? I know usually factories use compensated capacitors (or other similar components) to compensate the reactive power, so if I use the apparent power, it's not the real power consumed.
