According to Dave Ranieri, Vice President and General Manager, Lithonia Lighting(R) Commercial Indoor Products, LED lighting choices are flooding the marketplace from all over the world. As LED luminaires move into the ambient lighting mainstream, it is more important than ever to separate fact from fiction and distinguish quality lighting solutions from inferior ones.

As a result, the firm expects to provide the industry with tools to make the best possible decisions when selecting intelligent LED lighting and control systems.
