STONEHAM, Mass., July 11, 2017 /PRNewswire/ -- The harmful effects of conventional LED lights at night, which disrupt circadian clocks and increase appetite, insulin resistance and diabetes risk, may be avoided by removing bio-active blue wavelengths from white LED light, according to a research study titled "Taking the Obesity and Diabetes Risk out of Light at Night" to be presented by Dr. Martin Moore-Ede, CEO of Circadian Light at the "Light for Health and Wellbeing" Conference in Newport Beach, CA on July 27, 2017.

August 30, 2017 – Dr. Martin Moore-Ede, CEO of CIRCADIAN Light has been invited to speak at 2018 Strategies in Light Conference in Long Beach, CA from February 13 -15, 2018. Dr. Moore-Ede will be speaking about the negative health implications of being exposed to too much bio-active blue light at night. Learn more

ABSTRACT: Conventional energy efficient fluorescent and LED light in the 3000K – 4000K CCT range emit 15-25% of their irradiance in bio-active blue wavelengths which have significant impact on human health and performance. During the day, these conventional light sources improve alertness, vigilance, and productivity. However, exposure to blue-rich light during the evening and overnight hours has been correlated with an increased risk of obesity, diabetes and metabolic syndrome, in animal and human studies.

We have developed LED light sources that regulate bio-active blue light over 24-hours and emit white light (3200K CCT, CRI >80) at night with 90% less bio-active blue content than conventional LED lights. To investigate the benefits of removing the bio-active blue content at night, in a cross-over study, we compared 11 healthy human volunteers exposed to either conventional LED lighting or to blue irradiance depleted CIRCADIAN® LED lighting for two – three successive 12-hour night shifts.

Under the blue-rich conventional LED lights the subjects developed significant increases in insulin resistance and in appetite throughout the study. No significant increases in insulin resistance or appetite were seen after night shifts illuminated by bio-active blue depleted CIRCADIAN Light.
