Lighting in the Workplace

by Kate Venturini, Account Executive at BSIlighting in the workplace

Lighting can have an inspirational effect on design.  It is the essential element that can enhance or diminish the rest of the design.  Finding the proper balance between quality and quantity of light will not only enhance the environment, but will make occupants feel more comfortable – which in turn contributes to productivity.

Good lighting has a direct impact on human mood and social behavior.  It can help curb fatigue and lack of concentration.  In a study completed by the National Center for Biotechnology Information, researchers studied the impact of light on psychological mood in indoor work environments.  The study found that workers’ moods were at their lowest when “the lighting was experienced as much too dark.” Workers’ moods were at their highest level when “the lighting was experienced as just right.” However, too much light or conditions that were too bright, caused workers’ moods to decline.


Proper lighting is not only a good design decision, but also an ergonomic requirement.  Because lighting influences personal well-being, it also leads to motivation and performance.  In the workplace, 80% of information is processed visually.

  1.  EYE STRAIN:  According to a study by Cornell University – which looked at the effects of poor lighting on workers productivity – 24% of workers experienced vision problems that resulted in work time losses. This averaged 15 minutes per day.  Over 1 year, these losses amounted to one week of LOST work time per employee!  Prolonged periods of eye strain can also take a toll on the body’s energy levels, which affect mood.
  2. GLARE:  Glares are a result of poor lighting in the workplace when light reflects off walls, surfaces and computer monitors. According to the California State Compensation Insurance Fund – “Continued exposure to surface glare can cause eye strain, headaches and overall worker fatigue. In some cases, people may try to adapt to glare by adjusting their bodies into awkward positions. The risk of muscle and back strain can develop.”
  3. ENERGY LEVELS:  Circadian rhythms – which determine one’s waking and sleeping cycles – can be negatively affected by poorly lit workplaces. When disrupted for long periods of time, the body’s energy levels begin to decline which ultimately impacts a person’s psychological or emotional state.

Can you imagine losing productivity in the workplace because of poor lighting?  How does it feel being in the dark about such an important aspect of your business??
