Innovative, sustainable products inspired by the mechanisms of nature. Our R&D lab has dedicated over 20 years to research on the impacts of light on the human body. 

Our  scientists and engineers were among the first to develop lighting systems to help regulate healthy sleep-wake cycles for astronauts in outer-space. Here on earth, we design lighting products for all with the mission to improve well-being, twenty-four hours a day. 

Proprietary Spectrum technology provides comfort and quality. In order to develop and evaluate effective lighting solutions, Lighting Science Group utilizes latest metrics for biological impact and standards for wellness design proposed by leading experts.

Our GoodNight spectrum is custom engineered to minimize light energy exactly where it would trigger and disrupt the natural sleep-wake cycle –too prominent in conventional LED, fluorescent and incandescent sources for use before sleep- providing a rich warm illumination with high color rendering inspired by candle light.  

Our GoodDay spectrum is custom engineered to provide light energy exactly where it is relevant to the circadian system, and largely missing from conventional LED, fluorescent and incandescent sources- providing a rich white illumination with high color rendering inspired by morning sunlight that supports alertness, mood and performance.  


Lighting Science partnered with well-published leading experts in the field of light and health to provide you with the best advice and products.


Dr. Steven Lockley
