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
This method is generally used for Outdoor Lighting purposes

We say that if voltage in a power system is increased,for a constant power the current will decrease (by P=VI). isn't this in disagreement with the ohms law(I propotional V;resistant const.).Since the resistance of transmission lines remains constant,shouldn't inc in voltage cause inc in current across the transmission line? I have read many articles across the net but still couldn't this figure this out. :( Guyz plz assist me with dis..:)..
