Title Task lighting - Yet another view.

Abstract Report on recent laboratory studies of the relation between illumination levels and visual performance efficacy in view of energy costs. It is concluded that at least for some tasks there may be an optimum lighting level, with performance falling off with either more or less light than optimum, and that at average levels in the range of 30-75 footcandles problems associated with glare from the lighting are minimised. The data demonstrate that, in most cases, for material normally occurring in an office environment, increased illumination is not an effective economic choice.
