Recently, General Nutrition Centers (GNC) has adopted Science Group's  high-performance and ultra-efficient LED bulbs at its corporate owned locations across the country.

It’s said that the ENERGY STAR® qualified LED bulbs now lighting GNC retail display shelves are approximately 80% more efficient than the halogen bulbs they replace, are fully dimmable and have approximately 50% more lumens than competing products.
Asides from that , the stores will also save money on maintenance and cooling costs, since the company's bulbs will last 50,000 hours and give off very little heat unlike the halogen bulbs that they replace. 

As such, GNC estimates that the lighting upgrade will pay for itself in one to two years—with energy and maintenance savings continuing to shave costs from the retail chain's bottom line for many years thereafter.
