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.

CEOCFO: Dr. Moore-Ede, what is the premise and concept behind CIRCADIAN Light™?
Dr. Moore-Ede: CIRCADIAN Light™ fixtures control the blue spectral content of white light across the 24-hour day which is critical to human health and productivity. Medical research has shown that people exposed to light at night have a much higher risk of obesity, diabetes, heart disease, and certain cancers such as breast cancer and prostate cancer. For example, women who regularly work night shifts and are exposed to light at night have 65% higher rates of breast cancer. The problem lies in the blue content of white light. Special melanopsin-containing photoreceptors in our eyes detect the blue content of light and use that to control our circadian rhythms. During the day, this blue light content boosts alertness, mood and productivity but at night it resets our circadian clocks and disrupts the cancer protecting hormones. Unfortunately, conventional energy-efficient LED lights are rich in the very same blue wavelengths that maximally disrupt circadian rhythms at night and directly trigger the disease pathways for diabetes, breast cancer and other diseases. By precisely regulating the blue content of LED light across day and night, CIRCADIAN Light Fixtures maximize health and productivity around-the-clock without compromising light quality.
