When people can see better, they work better.
A typical industrial facility houses many people engaged in a wide variety of visual tasks. The task may be small, such as assembling a circuit board, or large, like operating a smelting furnace. Tasks may involve movement of objects, the viewer, or both.  Well designed lighting systems can make a direct contribution to the success of the operation. They can enhance form and function, enhance workers’ visual comfort, improve safety and security and create flexible spaces that adapt to the task at hand. Unfortunately, lighting it is often treated as an afterthought during the initial building design phase.  More attention is given to the physical dimensions of the production floor, process and production flow and equipment.     
Providing successful lighting systems for today’s industrial facilities is a complex task, requiring a wide breadth of experience and knowledge on the part of the designer.  Specific requirements will vary depending on the type of industry and location of production processes and buildings within a large complex.
These and many other lighting design considerations, are covered in greater detail in the IES Recommended Practice for Lighting Industrial Facilities.
