The green lighting revolution is in full swing. Activists are praising environmentally friendly lighting for its energy saving benefits, and businesses are saving money by switching to green—one Las Vegas Furniture company saves $182,00 per year by switching it’s 50,000 square-foot facility to energy efficient lighting. If the government follows the same path to eco-friendly illumination their savings would be in the billions. Msi Lighting, an energy-efficient bulb manufacturer, estimates that customers can save up to $2 billion over the lifetime of one of their bulbs, which is 25 years.
