American Conference of Governmental Industrial Hygienists (ACGIH)
In 2018, ACGIH published on the Notice of Intended Changes, a statement on the occupational health aspects of new lighting technologies. It describes the circadian, neuroendocrine and neurobehavioral effects of light. Over the past decade a revolution in indoor lighting has been underway, fueled partly by the new technologies of compact fluorescent lamps (CFLs) and solid-state, light-emitting-diode (LED) lamps, and partly by efforts to reduce the consumption of electrical energy. Do these changes in the work environment pose any health concerns?
The ACGIH TLVs for Light and Near Infrared Radiation for evaluating optical radiation have existed for decades and lamp safety standards refer to these TLVs®. These guidelines have been developed to avoid retinal injuries from exposure to very intense light sources (e.g., welding arcs). In most workplace settings, there is little chance that workers will be exposed to general lighting sources (GLS) used for visual purposes that exceed current TLVs.
