Lighting can account for as much as 40% of your total electric bill. Inefficient, outdated lighting systems may also produce more heat, which puts an additional load on your air-conditioning system. LED technology also provides many additional advantages over incandescent, fluorescents, and compact fluorescent lamps and lighting devices. This includes an exceptionally longer lifespan (60,000 hours), significantly lower energy consumption (90% more efficient), reduced maintenance costs, and higher safety.
