L              Lower Value
R             Recommended
H             Higher value  

Higher valuesshould be used at exceptional cases where low reflectance or contrasts arepresent in task, errors are costly to rectify, Visual work is critical,accuracy or higher productivity is of great importance.

Lower values should be used at exceptional cases where reflectance or contrasts are unusually high, speed and accuracy is not important and task is executed occasionally.  

Recommended luminance for chemical industry can be used for assessing lighting installation and managing lighting efficiently.
