Using dynamic technology that was first developed in collaboration with NASA to support the circadian rhythms of astronauts on the International Space Station, the JOURNI portable circadian LED light gives you the best of our popular, circadian lighting spectrums in one sleek, low-profile and portable device. Now you can enjoy the flexibility of having the proper, healthy light at any time of day. Designed using Lighting Science’s patented GoodDay® and GoodNight® spectrum technologies, JOURNI allows you to easily change from the warm, sleep-enhancing spectrum of GoodNight to the alertness and focus enhancing spectrum of GoodDay, with a general Illumination setting in between.
