If you have kept up with the 2017 Nobel prizes, you know three Americans won the prize in physiology or medicine for their discoveries of molecular mechanisms controlling the circadian rhythm. For the nonscientific community, the Nobel Prize Twitter account described it this way: “Our biological clock helps to regulate sleep patterns, feeding behavior, hormone release and blood pressure.”
For an electrical contractor-centric take on this emerging field, Craig DiLouie explains the four major factors in designing a lighting system in the aptly named “Circadian Lighting.” In “Expanded Reach,” Chuck Ross writes about the tunability of LEDs, the way they render color and the effects of light on human health.
Jeff Gavin brings us a look at citified agriculture in “Urban Farms Shine On.” This is not growing herbs on your windowsill; it is the super scientific deployment of LEDs that leads to resource-efficient crops.
Our fourth feature, which you can glimpse on the cover, is about the Many Glacier Hotel in Montana’s Glacier National Park. Under some rare and challenging conditions, Electrical Systems Inc. updated the lighting at the 100-year-old national historic landmark.
In the Integrated Systems Contractor supplement, Claire Swedberg writes about the revived popularity of neon lighting. Deborah O’Mara discusses power over ethernet innovation. In the Fire Focus, Wayne D. Moore writes about his skepticism concerning intelligent buildings. Has he come around?
Our products editor brings you some cool and unusual luminaires in our featured products section.
The Nobel Prize-winning scientists we mention above, who probably never thought they would get a shout-out from Electrical Contractor magazine, are Jeffrey C. Hall, Michael Rosbash and Michael W. Young. Congratulations to them!
