City hall parking garage lights in Austin are replaced by LED.

The Austin city major decided to change all the lights inside the city hall parking garage. All the lights will be replaced by the new LED technology lights. Because of the time of garage lights are switched on, the major agree with the project for the parking.

The project will be the replacement of all the lights inside the 750 places parking garage. The city has chosen LED technology, because those new products offer the opportunities to rule out all problems that the city had with the old lighting products. For instance, the problem of the energy bill will be solved thanks to the LED. Indeed, the old lights consume too much energy during the working time of the parking. However, the new lighting technology helps to reduce significantly the electricity bill, by 74%. Moreover, the parking lights are switch on 24 hours/days, and the maintenance costs are definitively high. With the new project, that cost will be decrease because the LED products have a better lifespan than the incandescent lights or the HPS (High Pressure Sodium) lights.

The project cost is $7.5 million grant provided through the American Recovery and Reinvestment Act of 2009 (ARRA), the city expects to have a fast return on investment. The first year, they expect to save $46,000, and increase this saving amount each year.
