With mounting heights now reaching up to 21 m, dedicated, high performance optics are required to ensure an efficient lighting design. Modern warehouses will often have large areas of the roof that allow daylight to pass through, making lighting control essential. With the use of integral sensors, artificial illumination is only used when needed, saving the client energy and money whilst also reducing carbon emissions.
In areas with racking it is especially important to guarantee good levels of vertical illumination.
Whilst there are often high levels of automation within these facilities it is still important to be able to read a label on a carton or pallet.
For recommended lux levels please see CIBSE : SLL Lighting Guide 1 - The Industrial Environment (2012, updated 2018)
|Application||Minimum maintained mean illuminance (lux)||Illuminance uniformity (minimum/average)|

|Continuously occupied storage areas where identification requires only limited perception of detail||200||0.40|
|Continuously occupied storage areas where identification requires perception of detail||300||0.60|
|Automatic high bay rack stores: Gangway: unmanned||20||0.40|
