The Path To Illumination

About Us

Dedicating his life to lighting design, Glenn M. Johnson developed

The Adaptive Method®

The Adaptive Method® revolutionized the layering process of lighting architecture and coupled it with the thoughtful application of lighting controls. Our trademarked design processes have been developed over the last 30 years and are the most comprehensive lighting and controls approach available. 

Where the Magic Began

Glenn Merlin Johnson’s path had been laid early on which ultimately led him to become an industry leader in Artistic Illumination coupled with today’s latest technologies.

Having been exposed during the late 70’s & 80’s to San Francisco’s explosion of Interior Design and Architectural visionaries the mold was set.  Under the direction of his father Merlin, Glenn became enlightened to Lighting products and applications folded into architecture for the top 1% residents of “The City” and surrounding areas.  Always with a focus on the Art of Illumination, Glenn eventually wrote the book aptly titled The Art of Illumination; Residential Lighting Design published by McGraw-Hill in 1999.  His artistic approach to lighting landed his book as the premiere text in Architectural and Interior Design Studies in 25 Colleges and University Course work as well as garnered him National and International speaking and teaching engagements.   Most practicing professional Lighting Design firms mimic’s Glenn’s revolutionary layering process of illumination called “The ADAPTIVE Method®”.  Glenn’s illuminated pathway has guided him from the San Francisco Bay Area, to leadership positions and business ownership in Los Angeles CA, Boston MA and Salt Lake City, Utah with project locations across the globe.

Glenn served his lighting and electrical apprenticeship with Artistic Lighting & Electric Co. Inc. in the San Francisco Bay Area from 1974 to 1984.  I addition he studied Business Administration at College of Marin from 1975 to 1977, which ultimately led to securing his C10 General Electrical Licensure. Taking his own lead he shifted from the San Francisco Bay Area to the Southern part of the State serving the 1% clientele in Palm Springs, Newport Beach, Beverly Hills, Bel Air and Santa Barbara which launched his storied career as the Lighting Designer to the Stars.  Glenn founded Lighting By Design Inc. on Wilshire Blvd in Los Angeles in 1984 where Glenn served several of Hollywood’s most notable producers, directors and studio heads by adding his artistic lighting and technical touches to their massive estate homes.  Mr. Johnson was recruited to the Intermountain West by Spectrum Engineers in Salt Lake City, Utah in 1992. He served as a Principal and Vice President until 2002 where he assisted in growing Spectrum from a 12 Person start-up to 85 engineers and associates strong with offices in Salt Lake City, Phoenix, Arizona & Baltimore, MD.  Glenn once again with his consummate entrepreneurial spirit launched Adaptive Design Group Inc . in 2002 based in Park City, Utah with satellite offices in Boston, MA & Jackson Hole, Wyoming.  Adaptive Design Group Inc. is the premier Lighting, Dimming and Electronics’ Technology Design Group in the country.

Glenn excels not only in lighting and electrical expertise but also has defined significant process developments in the production of architectural/engineering drawings, details and specifications that have been the benchmark in the industry for communicating complex design and engineering systems.  Glenn’s technical designs and his vast experience led him to the product Invention table as well securing “6” US Patents for illumination systems and the like.   Glenn is also founder of GlennCo Inc. the manufacturer of “The Merlin Light®” the premiere magical fine art projector lighting systems illuminating the world’s most discriminating private and corporate art collections.
