New research on circadian entrainment and the expanding understanding of the non-visual photoreceptors makes headlines daily; we're up to five different types of ipRGCs in the retina. With a skeptical take on all the hype, lighting designers at Arup are taking a hands-on approach. They are exploring the technology
in-house and sharing results among their design teams across the globe. Jake Wayne, senior lighting designer, leads Arup's Boston lighting group, and Toby Lewis is a senior lighting designer at Arup's San Francisco office. They have developed and continue testing a dynamic circadian white lighting system in their own offices, with their own employees here in the US. Wayne and Lewis use this experience to educate clients: emphasizing psychological benefits, discussing the potential health and productivity impacts, and specifying flexible systems as the research evolves.
