Why LED Bulbs Rock!! - Green Living Guy
Excerpt From Green Lighting Book: In November 2009, 2,076 eleven-watt incandescent bulbs were removed from the iconic Reno Arch in Reno, Nevada, and replaced with more energy-efficient 2.5-watt light-emitting diodes (LEDs). This $62,180 retrofit is expected to reduce electricity demand by 92,011 kilowatts, saving $10,441 per year for “The Biggest Little City in the World.” The upgrade is part of a citywide energy and water efficiency plan that is projected to save $1 million a year and create 222 jobs. At the lighting ceremony, the old incandescents were passed around the crowd as souvenirs of the past. In California, Los Angeles International Airport (LAX) officials switched to LEDs for functional and outdoor lighting, reducing annual lighting costs by $55,000 and lifetime maintenance costs by $980,000. In Oconomowoc, Wisconsin, Sentry Equipment Corporation chose to light its newfactory almost entirelywith LEDs, both interior and exterior. The initial cost was three times more than incandescent and fluorescent bulbs, but this price premium is expected to be repaid within two years from electricity savings. The bulbs are expected to last for 20 years.
