Lighting technologies continue to evolve, with more choices available – both in terms of the underlying technology and the color spectrum – every year.
The facilities engineer should consider the integration of less physiologically disruptive lighting where appropriate. For example, recent studies have indicated the use of red spectrum lighting, which is less disruptive to circadian rhythms, results in the sustained reduction and stabilization of systolic and diastolic blood pressure. There may be locations appropriate for the installation of red filter sleeves over standard fluorescent lighting, typically in areas calling for background (versus task) lighting.
