1 Color Select Independent color temperature and intensity control for LED lighting

2 High quality lighting with adjustable color temperature and intensity has the power to enhance architecture, elevate aesthetics, and increase the energy efficiency of a space. But most importantly, lighting can improve the quality of life of the human beings who use it.

3 Rhythm of Light Over the past two centuries, the shift from a mostly agrarian society to a mostly industrial one has brought people indoors for most of their day. This means people are spending less time experiencing natural light and more time in the electric light of the built environment. This shift has had an effect on the human body s natural clock, which regulates our sleep/wake cycle. This clock, known as our circadian rhythm, is primarily governed by light. Researchers have identified special photoreceptors in the eye that are sensitive to light and regulate our nonvisual responses through the production of hormones - such as dopamine, serotonin, cortisol, and melatonin. In the right balance, these hormones aid in alertness, focus, stress management, and restful sleep. Disrupting this balance leaves people feeling tired, unfocused, stressed, and restless. A new metric called Circadian Stimulus (CS) quantifies the impact light can have on these hormones through the circadian system. Circadian entrainment is generally achieved with exposure to light of a high CS (0.3 or higher) during daytime, and a lower CS (0.1 or less) in the evenings. The planet s natural lighting cycle starts with neutral colors and low intensity light in the early morning, then moves toward more intense light and cooler colors by noon, and warm-toned, low intensity light in the evening. We evolved under this lighting. Today, long days spent bathed in electric light, most of which operates at a fixed color and intensity throughout the day, is exposing our circadian systems to a constant state of gray, throwing off the natural rhythm of our sleep/wake cycle. Our constant interaction with computers and personal electronic devices, with their cool light emitting screens, adds to the disruption. Now more than ever, we need dynamic control over the color and amount of lighting in our environments. New developments in LED lighting technology have made tunable white lighting easy and intuitive. USAI s Color Select enables independent control over color and intensity, and makes a wide range of Circadian Stimulus levels (from 0.01 to 0.6) accessible to specifiers and end users. Research suggests this range can support a healthy, more natural sleep/wake cycle. s innovative Color Select technology gives occupants and designers the ability to vary the color temperature and intensity of their architectural LED downlighting anytime using a variety of standard control options. Create cool, bright morning light to jumpstart the day, then vary settings according to your preference throughout the day, to warmer, softer evening light in preparation for a restful night s sleep. Color Select presents a new opportunity for designers interested in using the full color palette offered by natural daylight to create more comfortable environments for any time of day anywhere in the world. Color Select provides total freedom and flexibility, allowing designers and occupants to change or modify their color temperature and intensity to any desired setting. This is especially important as our scientific understanding of the biological, psychological, and emotional effects of light cycles continues to evolve.

4 Places and Possibilities The field of behavioral lighting research is rapidly evolving, yet it has already produced study after study that connects the quality, color temperature, and intensity of light in a space to the attention span, cognitive performance, mood, health, and quality of life of the people who use that space throughout the day. This underscores the broad application possibilities for Color Select to enhance the lives of people in a variety of settings. Healthcare The same fixture can provide cool, bright light for examinations, then adjust to soft, warm light for a homier, more restful patient room. This is especially important in elder care facilities, as older eyes require more light to synchronize the circadian rhythm.
