LFI 2013 attendees experienced the world’s global stage for innovation across the great spectrum of solutions from a diverse mix of world-renowned exhibitors that displayed the technologies and designs that will define the future.

The trade show featured the addition of two new product categories—solar power and software; the debut of the Exterior & Roadway Lighting Pavilion; and the expansion into Hall F of the Pennsylvania Convention Center.

The new Exterior & Roadway Lighting Pavilion and new conference track helped to advance the LFI 2013 performance with a focus on products and innovations specific to environmental lighting.

Hall F illuminated the future of new lighting technologies by featuring a well-known lineup of exhibitors.  Hall F gave attendees convenient access to extensive new product resources, a robust networking schedule in the Spotlight Lounge, the LFI Media Marketplace and in-hall broadcasts from LFI NEWS.

LFI Mobile App usage increased nearly 10 percent over last year, and the app offered enhanced features to assist attendees with a personalized schedule, tools to easily and quickly navigate the trade show floor and quick access to important event information to provide the ultimate on-site experience.  It was also one of the ways that attendees could enter the grand prize giveaway.
