Auditorium; lower illuminance level

You need to upgrade to the tenth version, so much more in it including table 24.2. Well, the recommended lighting levels in an auditorium vary depending on what main activity will be. So the few activities that a typical auditorium have occurring, lecturing and performances. So for lecturing, and this depends on whether AV is involved and noted taking is required, ranges from 10 fc to 100 fc. Performance lighting levels, on stage, anywhere from 2 to 1000 fc depending on the activity. There are two pages of lighting levels for auditoriums, remember, these are electric lighting levels and not daylight levels. People are more acceptable to the variances in daylight then electric light. I would look at providing at 10 to 25 fc minimum for the audience area of the auditorium. This way it would handle lighting levels for lectures and note taking. The stage, I would not worry about what you provide there based on the multitude of things that will occur there.

Hello, please tell me what is acceptable for daylight in an auditorium for munimum fc.  I do not want to purchase "The Lighting Handbook v10 for $600.00. The sentence below (copied from the response above) is a bit confusing to me as I need to know if the recommended is 10-to 25fc of daylight.  In short, what is the minmum fc the Daylight Credit will allow me to have in an auditorium?   "I would look at providing at least 10 to 25 fc minimum for the audience area of the auditorium."  It would be great if someoe would send me The Lighting Handbook tables.
