Key Takeaways

LED lighting is being rapidly adopted in all industries and homes due to energy and cost reductions and longer product life.

Current research has provided new insight on numerous impacts of lighting on human health and productivity.

New metrics and instruments are needed to monitor and manage these issues. This article provides a review of the emerging issues regarding lighting that are important to the OSH professional.

Visible light is all around us, from sunlight to street lighting and automobile headlights to the backlight on a smartphone and in nearly every indoor space. Humans are so accustomed to working and living in artificial light that many of us have not stopped to consider the implications. Most OSH professionals’ experience with light and artificial lighting is likely limited to assessing whether sufficient light exists for people to see where they are going or carry out a task, or whether a light is too bright. This article aims to provide a current review of lighting for OSH professionals. Such a review is timely due to emerging issues including energy efficiency, human health impacts (e.g., blue light hazard, circadian rhythm disruption, fatigue), human performance (e.g., visual performance, visual comfort) and environmental impacts (e.g., light pollution).
