For nearly two decades, USAI has been a recognized leader in the design and development of high quality and innovative point source light fixtures for the full spectrum of commercial and residential projects.

Our collections of precise downlights, adjustable and wall wash fixtures are available for use with low voltage, compact fluorescent, metal halide, incandescent and halogen sources - providing optimum solutions for all needs and applications.

USAI continues to be owned and operated by members of the Littman family - whose 70 year heritage in the lighting industry dates back to the 1930's. Today, we remain committed to the same level of innovation that led inventor and family patriarch William Littman to bring fluorescent lighting to the mainstream of American architecture at GE's 1938 World Fair exhibit.

USAI is proud to be known and relied on for providing unparalleled service and high quality, technical and performance-based products for major projects of all types nationally and internationally.
