For those of you who may not know, the Occupational Safety and Health Administration (OSHA) has issued requirements for workplace lighting (below is the chart). The reason for this is that OSHA discovered that different offices, industrial facilities, and other workplaces were lighting their spaces differently. Many, in fact, were under-lit. As a result, workers errors increased, and productivity was not nearly as efficient as it could have been. But when switching to low-energy, LED lights, a significant reduction of workers mistakes occurred, saving that specific business money.
In the research study entitled "Lighting appraisal, well-being, and performance in open-plan offices: a linked mechanisms approach", the researchers concluded that:
"This is the first time the complete path from lighting conditions to feelings of health and well-being has been demonstrated. This is a first step towards the demonstration that better quality lighting can support organizational productivity. Other researchers have demonstrated that satisfaction with lighting contributes to greater environmental satisfaction , which in turn leads to greater job satisfaction and that higher environmental and job satisfaction leads to greater organizational commitment and reduced intent to turnover. Moreover, organizations whose employees are more satisfied show better customer satisfaction and business unit performance."
The following is the minimum standard for lighting in different employment environments. The unit of measurement is foot-candles, which is defined as "a unit of illumination equal to that given by a source of one candela at a distance of one foot (equivalent to one lumen per square foot or 10.764 lux)."
Take a look! Is your work space lit effectively enough for you?
