Illumination Levels
The requirements will vary depending upon the industry, but typical values are 200 - 300 lux in automated process areas, 300 - 500 lux where manual operations take place and 500 - 750 lux in inspection areas.
The CIBSE: SLL Lighting Guide 1 - Industrial Environment 2018 provides guidance for specific industries and processes, although many companies have their own engineering standards.
| Application | Minimum maintained mean illuminance (lux) | Illuminance uniformity (minimum/average) |
|---|---|---|
| Process areas | 300 | 0.60 |
| Sorting and washing of products, milling and mixing | 300 | 0.60 |
| Automatic processes | 200 | 0.40 |
| Inspection | 750 | 0.70 |
