Simple Lighting Layout Estimator 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. Use the lighting layout tool below to adjust desired foot-candles, reflectances, room size and more to upgrade an application or build a new space with the right product and maximized energy savings. Some or all lights can also be put on dimmer switches. You can delete any luminaire if you don't need it anymore by clicking the rod cross in its tab in the luminaire tap window. For those using metres, one lux is equal to 1 lumen/square metre. A lumen (symbol lm) is a measure of the total amount of light visible light emitted by a source in any particular direction. I explained the Lighting Design Calculations by Using Excel Spreadsheets in the following previous article: The interior tool use The lumen method to determines average illuminance achieved on the workplane using a derived property of luminaire photometrics and room geometry called the coefficient of utilization. For food preparation, we'll want more like 50 to 100 footcandles.
Compare this number to the chart above to get a feel where in each range you prefer your lighting. The Visual Design Tools are a set of web based tools that allow users to analyze many common lighting scenarios and view photometric files.
