Humans gain about 85 percent of their sensory input and their understanding of the world through their sense of sight, and in the workplace, proper lighting can make almost any task easier and reduce avoidable errors. Appropriate lighting can diminish the risk of fatigue and headaches, but it can prevent accidents and injuries on several secondary levels. For example, when lighting is appropriately bright, steady and glare free, employee vision can adjust quickly as the sightline moves from close up to far away. Small objects are easier to see, and so are safety hazards like moving vehicles and people.

In a fast-moving workplace, momentary blindness, glare, and poor contrast can be dangerous to employees and damaging to productivity. Keep these considerations in mind as you look around your workplace and make changes to your lighting structure.


The best possible source of light is natural sunlight. This type of light includes all the colors of the visible light spectrum (which electric lights do not), so they provide the most accurate representation of object color and contrast. This is also the healthiest form of light for employees, for reasons that are still not fully understood. If the structure of your workplace allows ample natural daylight, take advantage of this and use the sun as your primary source of workplace lighting.

Electric Lighting

Typically, even a full wall of windows with maximum sun exposure won’t be enough to provide adequate lighting, since the workday may continue into the evening and some days are cloudier than others. So as you develop a system of electric interior lights, divide the needs of your employees into three categories: generalized, local-generalized, and local (or task) lighting. Small, close-up tasks will require the brightest level of individual lighting, which should be controlled and customized by the user.

Solve lighting problems

The most common workplace lighting problems typically result from glare, insufficient light, poor light distribution, and flicker. In order to stay on top of these problems and get them corrected as quickly as possible, you’ll need to stay in close contact with your employees. Distribute regular surveys to make sure your teams are comfortable with the lighting in their work zones. If problems are reported, fix them immediately by changing, shielding, or replacing light sources.
