Scientists have long understood that the hue and intensity of light can have strong biological effects on humans. Technology built to take advantage of these biological effects up until this point has been too expensive for the general public to access. Bulbs that are designed to replicate different levels of natural light have cost upwards of $300,000 and are used mostly for astronauts to simulate a 24 hour Day/Night cycle.

LED technology has now reached a point where it is less expensive and more sophisticated, which is allowing more companies to create products that are accessibly for the ordinary consumer. Most notably a product called the “Sleepy Baby,” developed by the Lighting Science Group, is affordably priced and designed to help babies sleep.

A recent publication in the New York Times explores the broadening Biological Light market and the science behind it. You can check that out right here.
