Good Lightning

Adapted from content excerpted from Better Work, a partnership of IFC and the International Labour Organization

Proper lighting conditions are critical for good productivity. Many employers have found that lighting improvements have improved productivity by 10 percent, and reduced errors by 30 percent. Conversely, poor lighting can cause eye strain, fatigue and headache.


✓ Improved quality and higher productivity.

✓ Decreased fatigue and work-related illnesses like eye strain and headaches.

✓ Improved health condition of the workers leads to a decrease in absenteeism.

Good practices for good lighting

• Make full use of natural lighting through windows or skylights. This reduces electricity bills and improves the work environment.

• Workstations that need more light should be moved closer to windows.

• Use a combination of natural and artificial light and adjust lighting to the task-related types of work.

• Interior color affects how much illumination is needed. Ensure that ceilings are as close to white as possible. Use pale colors on walls.

• Use local lighting when necessary for some types of work.

• Re-orient the workstations to maximize use of available light.


• Provide more windows and skylights throughout the entire factory. These should be cleaned regularly.

• Install more light where necessary.

• Regularly maintain lights by dusting off light sources, replacing lights at regular intervals, and cleaning dirt on walls, ceilings, windows, and skylights.

• Observe workers and ask them about their vision problems.

• Contrasting colour paint for a tabletop or a partition between workstations is suitable for a visual background.
