Lighting Science announced the release of a new daytime productivity and natural sleep cycle lighting solution. The Good Day&Night® Downlight combines the company’s popular, patented GoodDay® and GoodNight® LED spectrum technologies into a single, easy-to-use luminaire. The new downlight is a comprehensive solution that enables residential and commercial customers to optimize daytime alertness, while also enhancing their nighttime sleep environment. Based on technology developed in collaboration with NASA to support the natural circadian rhythms of astronauts living onboard on the International Space Station, the Good Day&Night solution enables users to easily change between focus-enhancing and sleep-enhancing spectrums. The luminaire is controlled via a standard wall switch, or by a wireless switch accessory. Mounting kits are available for retrofit and new construction, providing living spaces with energy-efficient, circadian lighting for both day and night in any area of user home or workplace in a sleek, functional design. The first commercial installation of the Good Day&Night Downlight will be in New York City at Manhattan’s new luxury condominium development, Gramercy Square. Partnering with MNDFL, New York City’s premier mediation studio, the team worked collaboratively to create special wellness-focused amenity spaces. The downlight will be installed in the meditation room, and in several shared areas, offering residents healthy, biologically-balanced light.
