LEDs Magazine is pleased to announce the product finalists across 19 technology categories in the 2019 Sapphire Awards.

Sapphire Awards finalists forge new paths in solid-state lightingFollowing the recent announcement of the Illumineer of the Year shortlist, LEDs Magazine is rolling out more finalists for the annual Sapphire Awards. This time we are featuring the exciting product developments across 19 technology categories that represent the entire LED and solid-state lighting (SSL) supply chain, from enabling components and test tools to controls and lighting end products. All of the leading-edge products on this list demonstrated the qualities expected in the awards program — viability for commercialization, reliable and efficient performance, contribution to profitability, and ease of use.

A recent study by the Lighting Research Center at Rensselaer Polytechnic Institute found that a daytime lighting installation in a long-term memory care facility improved the health and well-being of patients.

Individuals with Alzheimer’s disease and related dementias often have trouble sleeping and experience daytime irritability. The study assessed whether customized daytime lighting could improve the sleep and mood of Alzheimer’s patients living in long-term care facilities.

 CIRCADIAN Light has just been approved by the American Institute of Architects to offer AIA Continuing Education courses for Health, Safety, and Welfare credits.

Our first course offering is called "Circadian Lighting for Workplaces: Protecting Health and Improving Productivity." The course will educate architects and lighting designers that are specifying circadian lighting and want to gain an understanding of the key differences between the day, evening and nighttime impacts of the blue content of white light on circadian rhythms, human health and productivity.

More than 20 years of scientific research reveal that exposure to blue-rich light in the evening and at night increases the risk for certain types of cancers.

The subject was further explored in 2007 by the International Agency for Research on Cancer (IARC) and the World Health Organization (WHO), which revealed that shift work that impacts natural circadian rhythms is “probably carcinogenic to humans.”

Further exploration of the 2007 findings revealed: 

  • Breast cancer increased 32% - 58% in women regularly exposed to light at night.
  • Prostate cancer increased up to 200% in men regularly exposed to light at night.
  • Blind women have a lower risk of breast cancer, and blind men have a lower risk of prostate cancer that is related to the degree of visual impairment.

CIRCADIAN Light LED Breakthrough Verified by UL: White Light with Less than 2% Blue Content at Night 

STONEHAM, MA -----   The significant health risks linked to the use of LED lights at night may have finally been solved by an innovative new LED technology. CIRCADIAN® Light’s new Night-Safe™ LEDs are the first lights verified by UL, the leading global safety certification company, to emit white light with less than 2% blue content at night. This medically-significant breakthrough addresses the growing scientific evidence that exposure at night to the 10 - 30% blue light content of conventional LEDs has a profound negative effect on many aspects of human health and performance.

More than 15 years of scientific research show that exposure to blue-rich light in the evening and at night increases the risk for cardiovascular disease by as much as 40 percent for night shift workers.

Most energy efficient LEDs in the market today are rich in the blue wavelengths that at night trigger the metabolic processes involved in hypertension, atherosclerosis, and cardiovascular disease through:

1.) Disruption of the circadian system (phase shifting and circadian misalignment)
2.) Melatonin-suppression and phase shifting
