How do you calculate lux levels, and what are the required lux levels for roads, workstations, warehouses, and electrical substations?

Question

Accepted Answer

Lux levels are calculated using the formula Lux = Lumens / Area (in square meters). Required lux levels vary depending on the specific application.

Lux levels are calculated by dividing the total lumens of light by the area in square meters that the light is illuminating.
For roads, recommended lux levels range from 10 to 20 lux for residential streets to 50 to 100 lux for highways.
Workstations typically require lux levels between 300 to 500 lux for general office work, and up to 1000 lux for detailed tasks.
Warehouses usually need lux levels between 100 to 300 lux for general tasks, and up to 500 lux for more detailed work.
Electrical substations may require lux levels of 200 to 500 lux for safety and visibility purposes.
