SPECIFICATIONS
Light Conversion Formulas 1 foot-candle (lumens/foot2) = 10.764 lux
1 lux (lumens/meter2) = 0.0929 foot-candles
The Inverse-square Law
The inverse-square law states that the illuminant E at a point on a surface
varies directly with the intensity I of a point source, and inversely as the square
of the distance d between the source and the point. If the surface at the point is
normal to the direction of the incident light, the law is expressed by E=I/d2.
Cosine Law
The cosine law states that the illuminant on any surface varies with the cosine
of the angle of incidence. The angle of incidence qis the angle between the
normal to the surface and the direction of the incident light. The inverse-square
low and the cosine law can be combined as E=(I cos q) /d2.
