• Description:
  The basic units used to measure lighting, especially electromagnetic radiant power, light, luminous power, luminous power passing through a unit area, luminous intensity and luminous planar intensity of luminance, were defined and the effect of lighting on behavioral performance was reviewed briefly. A relationship has been established between the visibility of detection like tasks and the increase of illuminance. However, for energy conservation purposes and other reasons, the general lighting of a workplace cannot and should not provide the higher illuminance required for detailed tasks. This can be resolved by the wearing of lenses, using luminaires placed close to the desk, a contrasting stimuli, magnifiers, larger print and various devices intended to make fine tasks easier. The author concludes that more attention should be given to the lighting design for various visual responses rather to illumination alone, which does not relate directly to human responses, and that people elsewhere perform their tasks without difficulties while working at lighting levels which are half what they are in this country. Conservative lighting conditions are satisfactory for general activities.
