| inverse square law |
For directional lamps (ie, narrow spot, spot, flood, wide flood, etc.), a formula used to determine the relationship between the CandlePower (Cp) of the lamp, the Distance (D) the lamp is from the surface to be illuminated, and the FootCandle (Fc) level produced on that surface. If any two of the three elements are known, the third can be determined.
