Warehouses mostly have high ceilings and elevated shelves to store materials. The floor area is mostly the aisle area between the racks. The vertical lux level on the rack is critical to see and read the label of the stored items on the high-rise racks. Also, for the people and for the forklift drivers the horizontal lux level on the aisle floor is to be calculated.
In order to arrange the lighting layout properly as related to the functional requirements of different areas in the warehouse, the racking layout should be provided to the designer.
