ELLI serves the landscape lighting profession, consumer, lighting industry and the health care industry. It's purpose is to address the emotional aspects of light and nature, when combined. It's intent is to provide insight to the experience of 'feeling'--the "Affect". ELLI is an educational resource available to all. It provides for the betterment and understanding of the outdoor landscape lighting profession. It also serves as a means to measure one's skills, abilities, and performance. This is critically needed in the consumer market. The landscape lighting profession, as well as the lighting industry is segmented and there is no common message for the consumer to understand. ELLI is part of that solution. This message is "Betterment in Human Health". Everyone can understand this. Lighting is a critical element in life and it affects us psychologically and physiologically. We all must understand the importance of this.
