AUSTIN, Texas—An advanced lighting system from Ketra that mimics the color, temperature and intensity of natural light is now available to the residential market.

Offering a range of systems and light bulbs, Ketra LEDs dynamically shift throughout the day, providing the full range of sunlight—crisp and bright during the day, for example, and soft and warm at night, the company said.

Providing the wellness benefits of natural light to indoor occupants, synchronizing their circadian rhythms to support better health and rest, the system has previously been available only for commercial applications; the company cited Google, Pinterest and Whole Foods Market among its clients.

Ketra offers an integrated system of lighting, keypad interfaces and software. The lighting products—light bulbs and luminaires—communicate wirelessly to interfaces to control the light. Its LED light bulbs last up to 30 years in a typical home, significantly longer than standard LEDs, Ketra said. Ketra’s bulbs also maintain the exact output as each other, so all bulbs are always emitting the same exact amount of color and light. A proprietary semiconductor measures the bulb’s color 360 times a second, continuously ensuring that the light output across every bulb in the space is the exact color temperature of natural light, it added.

“From the beginning of time, humans have evolved under two natural light sources: The sun and firelight. Light from these sources aids in regulating physical processes and helps maintain mental wellbeing by aligning the human body’s circadian rhythm,” said Nav Sooch, CEO of Ketra. “As the survey data and bodies of other research reveal, natural light offers myriad wellness benefits. It stands to reason that today’s commercial and residential spaces should offer this high-quality light indoors. Ketra does just that.”

A Ketra study conducted by Harris Poll revealed that nearly 9 out of 10 Americans (89 percent) say that exposure to natural light has a major/moderate positive impact on mood, while 87 percent say that exposure to natural light has a positive impact on productivity, alertness and brain function. Nearly 8 in 10 Americans (79 percent) say that they wish they were able to spend more time outdoors during the day to get more exposure to natural light. The survey also found nearly 3 out of 4 Americans (73 percent) say that they would pay more for light bulbs if they knew the bulbs would have a positive impact on their health.

The MSRP of the full Ketra system is $5 to $15 per square foot of the home, depending on the product, how many lamps are used and other factors.
