Like many expecting parents, Tracy Mizraki Kraft in Portola Valley, Calif., worried about how her newborn would sleep. So she paid attention when her doctor handed her a light bulb that he said would help her son do just that.The small amber bulb, called Sleepy Baby, seemed to work well, she said, creating a soothing environment for Leo, now 16 months, as he drifted off to sleep.
For Ms. Mizraki Kraft, the bulb’s appeal was self-preservation. But it is part of a technological revolution coming to homes, offices, hotels and schools through lighting designed to undo the ill effects of artificial light — both overhead and on screen — and help regulate sleep, alertness and even people’s moods.Scientists have understood for years that different levels and colors of light can have powerful biological effects on humans. But that concept has been applied only with expensive bulbs — costing as much as $300,000 — for specialty applications like mimicking the 24-hour cycle for astronauts or treating jaundice in newborns.
