Simple Indoor Lighting Layouts
These estimators provides a rough lighting layout for industrial (high ceiling area) or office (low ceiling area) open spaces assuming average or typical surface reflectances on walls and ceilings. They are adequate for a “first pass” estimate. More accurate layouts can be done with the indoor design tool link available on the web page for the chosen fixture, or by using a commercial lighting layout program.
All numbers refer to initial lumens and footcandles only.
