ILLI was founded in 1990s by Janet Lennox Moyer, renowned landscape lighting designer, and became a non-profit in 2010.  The organization is governed by the ILLI Board of Directors.

Professionals and students in the field of landscape and lighting have an outstanding opportunity to learn design principles, gain practical experience, and explore a wide-array of the latest equipment available from landscape lighting manufacturers.

Our organization provides Instructors, or 'Mentors', for the ILLI Intensive Courses (IC).  Our Mentors are recruited from the long list of ILLI IC alumni who volunteer their time and their skills to teach and share their experience with a new generation of landscape lighting designers.

ILLI Mentors guide a new generation of landscape lighting designers through lectures and hands-on design to provide safety, security and beauty for lighted night landscape through during ILLI IC.
