How is lighting ergonomic? Notice the position you are standing or sitting in as you read this. Did you move to get better lighting? Did you position your body in a way to help improve the visual contrast of the text, reduce glare or avoid a shadow? That very movement is the essence of ergonomics.
How can lighting reduce operating costs? According to the US Department of Energy, 51% of the energy used in commercial buildings is consumed by lighting systems. However, many existing systems have much higher than recommended illumination levels from overhead lighting. In instances where too much illumination is provided through overhead lighting, companies can reduce their power usage and associated costs by simply reducing overhead light levels and applying proper lighting for specific tasks.
How does proper lighting increase performance? According to The American Optometric Association, excessive overhead or ambient lighting levels reduce the apparent visual contrast on computer screens due to glare.
The Bottom Line: Optimal task illumination levels through the use of task lighting will help improve user ergonomics, reduce operating cost and increase worker performance.
