12.1.2.3-1 General Illumination Levels

The overall general illuminance levels on worksurfaces in the control room where paperwork is required should be in the range of 200–750 lux (18.6–69.7 foot-candles (fc)). If visual display devices are used at the workstation, as in computer-based control rooms, the maximum illuminance should be 500 lux

(46.5 fc). For areas where tasks consist largely of paperwork, a minimum illuminance of 500 lux (46.5 fc) should be maintained.

Additional Information: These general illuminance values can be accomplished by a combination of ambient and task lighting. 26 11064-6
