The work plane is where the most important tasks in the room or space are performed.Measuring Units Light Level - IlluminanceIllumenance is measured in foot candles (ftcd, fc, fcd) (or lux in the metric SI system). A foot candle is actually one lumen of light density per square foot, one lux is one lumen per square meter. 1 lux = 0.0929 foot candle = 1 lumen /sq meter = 0.0001 phot1 ftcd = 1 lux / 10.7521 lumen/sq ft = 1 foot candle = 1x104 lux = 1 phot
