In a building in the area closest to the windows the light level may be reduced to approximately 1000 lux. Earlier it was common with light levels in the range 100 – 300 lux for normal activities. These figures are based on the recommended lux levels by CIBSE (Chartered Institute of Building Services Engineers) and the code for interior lighting. In general, low contrast and detailed tasks require more light while high contrast and less detailed tasks require less light.
