About Us

Illuminating the Complicated

Fifty years ago: we calculated average foot-candles on a workplane underneath linear fluorescent lighting in an empty room.
Today: professional lighting design has become considerably more complicated. It encompasses a multitude of lighting technologies, integration with other building systems, a focus on human-centric design, advanced controls, and a commitment to sustainability.

Our Purpose

To advance, support, promote, and contribute to innovation, science, and engineering in lighting, including lighting for health, horticulture, architecture, and entertainment. To drive progress in lighting, professionals actively support, promote, and contribute to innovation, science, and engineering. Lighting professionals continuously enhance our lives and surroundings.

ATLA Goals

With a focus on principles and practices, the organization encourages in-depth analyses and abundant references to scientific literature. By providing a platform for professionals to connect, ATLA facilitates meaningful discussions on a wide range of lighting-related topics. Members of ATLA engage in comprehensive conversations that drive the field forward.

    We have been using ultraviolet radiation as a means of disinfection for over a century. However, it has been the unfortunate events of the past year that have led to an explosion of interest in ultraviolet germicidal irradiation (UVGI) systems. From mercury vapour and pulsed xenon lamps to excimer lamps and ultraviolet LEDs, there have […]
