Abstract

Electric light has enabled humans to conquer the night, but light exposure at night can disrupt the circadian timing system and is associated with a diverse range of health disorders. To provide adequate lighting for visual tasks without disrupting the human circadian timing system, a precise definition of circadian spectral sensitivity is required. Prior attempts to define the circadian spectral sensitivity curve have used short (≤90-min) monochromatic light exposures in dark-adapted human subjects or in vitro dark-adapted isolated retina or melanopsin. Several lines of evidence suggest that these dark-adapted circadian spectral sensitivity curves, in addition to 430- to 499-nm (blue) wavelength sensitivity, may include transient 400- to 429-nm (violet) and 500- to 560-nm (green) components mediated by cone- and rod-originated extrinsic inputs to intrinsi-cally photosensitive retinal ganglion cells (ipRGCs), which decay over the first 2 h of extended light exposure. To test the hypothesis that the human circadian spectral sensitivity in light-adapted conditions may have a nar-rower, predominantly blue, sensitivity, we used 12-h continuous exposures of light-adapted healthy human subjects to 6 polychromatic white light-emitting diode (LED) light sources with diverse spectral power distributions at recommended workplace levels of illumination (540 lux) to determine their effect on the area under curve of the overnight (2000–0800 h) salivary melatonin. We derived a narrow steady-state human Circadian Potency spectral sensitivity curve with a peak at 477 nm and a full-width half-maxi-mum of 438 to 493 nm. This light-adapted Circadian Potency spectral sensi-tivity permits the development of spectrally engineered LED light sources to minimize circadian disruption and address the health risks of light exposure at night in our 24/7 society, by alternating between daytime circadian stimu-latory white light spectra and nocturnal circadian protective white light spectra.

REVOLUTIONARY CIRCADIAN® HORSE LIGHTING SYSTEM

THE RIGHT LIGHT IS ESSENTIAL FOR OPTIMAL HEALTH & PERFOMANCE: 

• Sleep cycles 
• Feeding patterns 
• Energy and Athleticism 
• Reproductive cycles 
• Hormone cycles 

• Horses Need Blue-Rich Light During the Day - Blue-rich light during the day entrains and strengthens a horse’s circadian cycle. In turn, this boosts alertness and energy during the day and improves sleep at night. 

• Horses Need Blue-Depleted Light After Sunset - Research has shown exposure to blue-rich light sources in the evening and at night disrupts the circadian rhythms of horses and suppresses melatonin. Circadian disruption interferes with equine sleep and reproductive cycles, as well as feeding patterns, and can lead to jet-lag symptoms which can impact performance. 

HEALTHY LIGHTING FOR OPTIMAL HEALTH, FITNESS, AND PERFORMANCE

GAIN THE COMPETITIVE EDGE IN FITNESS CENTERS 

BENEFITS OF CIRCADIAN LIGHTS FOR STAFF & MEMBERS

• Boost physical workout performance 
• Improves alertness, mood and sense of well-being 
• Promotes sleep at night and prevents circadian disruption 
• Reduces the risk of injury or accidents 

• Key market differentiator for prospective members looking for a new fitness center 
• Increases staff energy, performance and alertness

Improve Health, Safety, and Well-Being of Residents & Staff

IMPROVE QUALITY OF LIFE FOR EVERY STAGE OF SENIOR LIVING

Lighting designed to boost circadian rhythms and health is the key to healthy senior living and can make your facility stand out in an increasingly competitive marketplace. Most elderly people are deprived of the right kind of light during the day and are exposed to the wrong kind of light at night. Spending time indoors under inadequate lighting, disrupts the circadian rhythms of elderly residents negatively impacting their appetite, energy and sleep. The result is depressed mood, increased agitation, chronic fatigue and increased risk of falls and injuries. Traditional fluorescent and LED lighting provides too little healthy light that mimics the benefits of daylight and provides too much blue content after sunset resulting in sundowning, sleep disruption and health disorders.

Improve Health, Safety, and Well-Being of Patients & Staff

CREATE THE OPTIMAL HEALING ENVIRONMENT FOR EVERY STAGE OF PATIENT CARE

Lighting designed to boost circadian rhythms and health is the key to optimizing a higher quality healing environment in your healthcare facility. You can make your facility stand out in an increasingly competitive marketplace with Circadian Lights that improve health, wellbeing, safety and staff productivity. Most patients and healthcare staff are deprived of the right kind of light during the day and are exposed to the wrong kind of light at night. Spending time indoors under inadequate lighting, disrupts the circadian rhythms and negatively impacting appetite, energy and sleep. The result is chronic fatigue, depressed mood, and increased health risks of light at night. Healthcare Staff and patients are exposed to both traditional fluorescent and LED lighting which provides too little healthy light that mimics the benefits of daylight and provides too much blue content after sunset resulting in sundowning, sleep disruption and health disorders.

IMPROVE HEALTH, SAFETY, & PERFORMANCE IN YOUR WORKPLACE

Your company’s most valuable assets are the highly skilled employees running many critical areas of your organization. New standards like the American Petroleum Institute’s ANSI RP-755 recognize the importance of well-lit workplaces that prevent circadian disruption at night and the costly impact on an organization

To support key employees, your lighting systems should optimize safety, health, and productivity by minimizing circadian disruption. CIRCADIAN’S Zirc™ Technology

CIRCADIAN Zirc™ LED Technology:

• Addresses the Health Risk of Light at Night – There is substantial evidence about exposure to blue light at night and how it disrupts circadian rhythms, which trigger carcinogenic and metabolic processes and suppress health-protecting hormones like melatonin. In turn, causing fatigue-related errors, absenteeism, presenteeism and higher turn-over rates in your operations.
• Reduces the Cost of Circadian Disruption – The Jet-lag malaise that results from disrupted circadian rhythms resulting in low productivity and increased errors.
• Maximizes Alertness and Vigilance – Blue-boost during the morning and post- lunch combined with a blue-depleted light at night that maintains alertness, productivity, and reduction in errors.
• Light Training & Shiftwork Support Services – We can provide workforce training on managing fatigue, sleep and light with the installation as well as other shiftwork support services
