The significance of lighting planning
Lighting design can help overcome these issues by improving the clarity of lamp performance.
Luminaires must be photometrically examined, often by an impartial third party, in order to provide photometric files for professional lighting design (such as IES or LDT files).The lumens produced by a luminaire in the field are measured using a photometric test, not the total light output at the source.At this point, lighting design starts to matter a lot. Lighting design gives you a visual depiction of how the installation lighting solution will ultimately look, displaying light levels and spreading at the application site.This eliminates any unclear lumen estimates and gives a genuine sense of lighting performance before purchasing.
In order to make sure you get the intended light level, provide the lux level and then compare it to the lighting design report.
