Recommended values, which depend on type of activity, occupant age, and other factors, may be found on p. 460ff of the Lighting Handbook, Eighth Edition, 1995, Illuminating Engineering Society of North America. Typical values are shown in <a href="JavaScript:TL_10761.HHClick()">Table 28</a>. It is assumed that this lighting level will be produced by the overhead electric lights at full output . These setpoints may be chosen to be lower when the overhead lights provide ambient lighting that is supplemented by task lighting.
