Energy Source started by doing a comprehensive assessment of the 5,000-square-foot store. “LED lighting can increase efficiency by 80% to 90% compared to traditional fluorescent lighting, which operates at 20% efficiency, so the owners knew LED lighting could give them a significant savings on energy usage,” Katie Savino, program manager at Energy Source, told Energy Manager Today.

In addition to energy savings, the retrofit delivers much better lighting for shoppers, Savino noted. Other benefits she highlighted: increased light output, improved workplace productivity, improved sustainability, and reduced operating expenses for GNC. Upgrades pay for themselves in under three years, Savino said.

“There will also be a decrease in maintenance costs because LED fixtures have a longer operational lifetime, are built for durability, and they don’t burn out or break as quickly,” Savino said. “Some LEDs have an expected lifespan of 60,000 to 100,000 hours compared to fluorescents that only last 8,000 to 10,000 hours.”

GNC store owner Michael Saluzzi called the lighting upgrade process quick and clean. “The new LED lighting provides a much cleaner and brighter look to my store,” he said. “I’m looking forward to the future cost saving benefits.”
