High-Tech Lights to Help Baby Sleep

From the NY Times article:

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.

Now, with lighting technology, especially LEDs, becoming more sophisticated and less expensive, companies are developing so-called biological lighting for ordinary consumers.

The Lighting Science Group makes Sleepy Baby and is among the companies that are most devoted to the growing market for lighting to enhance rest or alertness, with bulbs like Good Night, and Awake and Alert.

But other companies, from start-ups to the biggest lighting manufacturers, have products promising similar results. General Electric announced this year that it would release a color-changing LED as part of its Align product line that is compatible with Apple’s HomeKit system and is meant to automate lighting according to the natural sleep cycle.

Two years ago, Philips introduced the Hue, a Wi-Fi-connected bulb compatible with Apple systems that offers “light recipes” conducive to waking up and winding down.

Digital Lumens, which makes and manages smart lighting systems for commercial and industrial settings, including supermarkets, is supplying lights for a study at Brown University aimed at controlling brightness and spectrum to promote learning among adolescents. And a company called LumiFi has an app to adjust lighting in homes and commercial spaces like hotels, with settings like Rest, Energize, Focus and Sexy.
