UK smart lighting and LED specialist PhotonStar said it has completed a circadian lighting installation at a dementia ward in London where the dynamically changing light levels are expected to improve patient health.

The head nurse on the ward at St. Mary’s Hospital requested the circadian lighting system for patient wellbeing as part of a broader ward retrofit, and the hospital justified the deployment on the basis of energy savings, PhotonStar group marketing and business development director Fenella Frost said. In a recent recap of the co-located LuxLive and Strategies in Light Europe conferences, we noted that representatives of two other UK hospitals were championing the health benefits of circadian lighting — also known as human-centric lighting — for patients and energy savings for healthcare administrators.

The system of 56 LED downlights at St. Mary’s is tied into a wireless PhotonStar control system called Halcyon that simulates daylight during normal waking hours by providing high visual and non-visual light levels. The non-visual frequencies, also known as “melanopic” lighting, includes light in the blue wavelength spectrum, which is associated with daylight and which suppresses the sleep-inducing hormone melatonin.
