True & False CIRCADIAN LIGHTING: How To Protect Occupant Health & Productivity 

Many lighting products are incorrectly labelled "circadian." This is because the word “circadian” has recently entered into lighting industry vernacular often with limited understanding of its precise meaning. This can create confusion for architects, lighting designers and specifiers. 

So, what is circadian lighting? In 2018 the IES and RPI's National Science Foundation funded LESA center workshop report concluded that, “Merely adjusting CCT, light intensity, or even SPD with time of day does not qualify a lighting system as 'circadian.' CCT color tuning products …should not be labelled 'circadian' unless they have been demonstrated through properly designed clinical trials to be capable of optimizing the phase, amplitude and/or entrainment of the circadian system to promote human health and wellbeing.”

This course reviews evidence-based research on the benefits of circadian lighting and will share how to distinguish between "true" and "fake" circadian lighting products.

Learning Objective 1: Understand the correct definitions of "circadian" lighting based on up to date medical research.

Learning Objective 2: Describe how the blue content of white light enhances health and performance during the day, but disrupts circadian rhythms and causes health risks during evening and night hours.

Learning Objective 3: Understand why fixed spectrum and full spectrum LED lights and many white color tuning products are not true circadian lights because they fail to prevent the risks of blue light exposure, and negatively impact human health and productivity.

Learning Objective 4: Learn how to correctly specify and incorporate circadian light into the built environment.

PRESENTER: Andrew Moore-Ede, CIRCADIAN Light

For over 10 years, Andrew Moore-Ede has been a consultant for CIRCADIAN®, the global leader in providing 24/7 workforce performance and safety solutions for businesses that operate around the clock.  When numerous research reports concluded that light exposure at night was disrupting circadian rhythms and negatively

impacting human health and well-being, Andrew’s clients asked a simple question: what lights should we be using at night to prevent circadian disruption? This led to an NIH grant to research and define the circadian spectral characteristics of light and ultimately to the creation of a new company: CIRCADIAN® Light.

Andrew is excited to be working for a company that is dedicated to developing evidence-based lighting solutions that feature specialized controls and spectrally engineered Day and Night LEDs designed to optimize human well-being and performance and minimize the impact of circadian disruption for our 24/7 world.
