Last week I spent 5 days in San Diego attending LightFair International 2016. This is an annual lighting conference to show case the newest technologies in lighting. There are many educational classes during this conference and this year was the first time that they offered a series on Lighting and Health. I attended a number of these offerings and am so excited about what I learned and saw on the trade floor. HCL- Human Centric Lighting is here! Several vendors showcased their Tuneable LED's, which are able to be programmed to change color from warm whites to cool whites to more closely match outdoor light and enhance our circadian rhythm. The classes I attended had studies that showed improvement in productivity, in sleep, and in the lives of people living with Alzheimer's disease with the use of tuneable LED lighting. So much of this knowledge and the products are cutting edge. I am looking forward to more products being available for both commercial use and use in homes.
