Lighting installations in offices and buildings are typically static and specified in terms of their effects via the classical visual pathway (e.g. chromaticity or brightness). However, it is now recognized that spectral variations in light elicit non-visual effects, including on emotion and cognition, via a distinct neural pathway, and it is important for health and wellbeing to take these into account.

Last spring, and for 9 weeks, we did an experiment in a real office setting to test whether dynamic sculpting of the light spectra in indoor environments using LEDMOTIVE downlighters, either to mimic natural daylight changes or achieve particular levels of non-visual vs. visual stimulation, may elicit different biological and behavioral effects. A work that was possible thanks to Prof. Anya Hurlbert from Newcastle University and the whole lighting team at ARUP London.
