Following our previous post, we enclose a guide to the recommended light level for different industrial and commercial activites:
Chemical activities; Transport industries such as train stations, gas stations, car garages, naval docks; Offices and administrations, Shops, merchandise shelves, small shops….
This guide gives the recommended minimum lighting levels for different types of work activities
Lighting should be sufficient to enable people to work, use facilities and move from place to place safely and without experiencing eye-strain.
If people have difficulty doing their job because lighting is too low then setps should be taken to improve it. However, if an area measured falls outside these levels, it does not necessarily mean that the whole lighting system needs to be modified. Other measures such as task-specific lighting might be more appropriate. Generally speaking, the finer the detail, the higher the light level required.
Outdoor light level is approximated at 10,000 lux on a clear day. In enclosed areas like commercial buildings, the light level may be as low as 25 – 50 lux. Additional lighting equipment is often necessary to compensate these low levels of lighting.
