Accuracy and rounding
Illuminance measures light arriving at a surface. It is different from lumens, which describe luminous flux.
Lux is lumens per square meter; foot-candles are lumens per square foot, using the exact international foot.
Whole lux values are usually enough for room surveys; calibrated lighting work should follow the meter resolution.
