Ketra Invents Natural Light

I am amazed by this marvelous new lighting product from Austin Texas-based company Ketra. It took four years to design a light that changes color temperature throughout the day, starting with bright white light just sunshine to a warm firelight-like glow in the evening. Research has shown that this candlelight glow in the evening and night hours helps our bodies produce melatonin and prepare us for sleep. (Even the newer phones and tablets now have a "Night Shift" option where the light from the screens is warmed, eliminating the bright blue-white light that stimulates the brain, making it harder to sleep.)

Ketra makes a variety of fixtures and lamps (bulbs) along with interfaces and apps to control them. Watch the videos below to see the products in action.

Happy designing!
