What Does Optimizing Light Levels Mean?
Optimizing light levels, within the context of workplace health and safety, refers to the process of selecting levels of lighting that are best suited to the needs of a specific work environment. When optimizing light levels, both the expected tasks to be performed in the workspace and the preferences/needs of the employees using that space should be considered.
WorkplaceTesting Explains Optimizing Light Levels
Optimizing light levels requires an evaluation of the job design and tasks to be performed in that location as well as safety considerations, user preference, and regulatory requirements. For example, in the U.S., the Occupational Safety and Health Administration (OSHA) has issued guidelines providing for minimum illumination levels in various workplace settings.
In addition, lighting studies have found that different tasks have different optimal light levels. For instance, the stated optimal illumination for a surgery theater is 1000 lux, while the illumination in a normal office environment is stated as approximately 500 lux.
After incorporating all of the workplace factors into a lighting design, it may be impossible to optimize light levels with just a single lighting solution. In most instances, a combination of lighting options including both room and task lighting should be provided. The right light level for a specific work environment improves both worker moods and productivity while reducing eye strain and fatigue.
