Welcome to the monthly Lighting for Health & Wellbeing newsletter for Sept. 26, 2022. Starting in the latter part of August, I’m always struck by the dynamic daylight changes — both the intensity at different times of day and the shortening of those daylight hours. You would think I’d be used to it by now. But I typically take advantage of comfortable temperatures to get outdoors more in autumn than I actually do during the summer daytime hours. It just feels right. I heard a lot about daylight and views last week at our LightSPEC West conference. I plan to share some of those perspectives over the next week; we will certainly be seeking more contributions from the industry on merging daylighting, electric lighting, and design principles to maximize human wellbeing.

In this issue:

• Our Mark Halper summarizes findings published in Science Advances that map out blue-heavy artificial light at night across Europe, and raise more concerns about potential negative effects of overly intense blue spectral content outdoors.
• The Design Excellence Awards–winning projects demonstrate smart integration of lighting and controls in ways that support the purposes of the spaces and adapt to occupant needs.
• Fraunhofer IBP has performed comparative testing of Nichia’s Dynasolis LED technology against standard white-light LEDs, indicating a favorable result on alertness and relaxation responses by subjects under the Nichia lighting conditions.
