Ari Isaak

Founder

Photometrics AI

Ari Isaak spent 25 years as a Geographic Information Systems (GIS) professional and came to lighting through asset management. He founded Evari Consulting in 2011, just as LED conversion was beginning, and led field operations and data management on large street lighting conversion projects including Chicago, Phoenix, San Diego, Philadelphia and Boston. Ari worked alongside lighting designers to determine which luminaire would be installed at each location. In 2024 he stepped away to start EvariLABS, which builds civil lighting design software for street networks rather than one design at a time. Its first product, EvariLUX, has run photometric calculations on approximately 290,000 street lights. He holds two issued U.S. patents, is a GISP and CFLC, and serves on the IES Roadway Lighting Committee.
