Lighting Science® Launches Good Day&Night Commercial Recessed Luminaires

Lighting Science®, renowned for its suite of human-centric LED lighting solutions, announces the launch of the Good Day&Night™ Troffers, which combine the patented GoodDay® and GoodNight® LED engineered spectrum technologies into one multi-dimensional circadian lighting product. The 2x2 and 2x4 troffers deliver biological benefits with high-quality light for peak visual performance, while providing the ability to control and personalize the spectrum of lighting – truly delivering the right light at the right time.

The Good Day&Night Troffers enable users to transition light according to the natural progression of the sun, helping to synchronize the body’s circadian rhythm.   Users can easily switch between the focus-enhancing GoodDay and the blue-depleted GoodNight settings. Lighting Science’s patented engineered spectra surpass superficial color tuning in circadian impact and quality of light, providing 90+ CRI and an R9 value >50 across the 2300-5000 CCT range. The troffers deliver 2600 lumens (2x2) and 5200 lumens (2x4) in the GoodDay mode. Light settings can be easily adjusted with a standard wall switch or the Lighting Science Wireless Switch for full multi-spectrum and dimming control. 

Lighting Science’s Good Day&Night portfolio supports the natural sleep-wake cycle, with numerous applications and benefits based on the indoor lives we often lead. For example, in senior living, research has shown that appropriately timed light exposure for Alzheimer’s and dementia patients results in increased sleep and decreased depression and agitation. Additional applications for circadian lighting may include hospital patient rooms, classrooms, offices, spa/wellness centers and training facilities. 

“Chronobiological research and education is leading to the inclusion of circadian lighting in compliance standards such as the WELL Building Standards®.  It is no longer considered a nice-to-have alternative, but a necessity,” says Meggan Kessler, Vice President of Marketing at Lighting Science. “With the expansion of our Good Day&Night product ecosystem, we have broadened our solutions for creating healthier built environments.”
