Calculate Foot Candles for Commercial Lighting

So how do you calculate foot candles for commercial lighting? There really is no calculator.

But there are lighting plans. A lighting plan takes an indoor or outdoor space and plots lighting within this space. Inside the software, a calculation is performed taking into account the lumens of the fixtures and the location of the lights. When the calculation is complete, calculated points are indicated on the floor indicating the foot candle reading at that location.
