National Mall’s Historic Lamps Upgrade to Energy-Efficient LEDs
On a chilly afternoon Jan. 30, a large group gathered on the National Mall to watch a resplendent sunset behind the Washington Monument. As darkness gathered, a coterie of dignitaries including Energy Secretary Steven Chu and Secretary of the Interior Ken Salazar flipped the switch on a new way the monumental national park, which attracts over 24 million visitors a year, will be lit at night. Finally dark, visitors saw 173 Olmstead lamps, which date back to the Great Depression, shine with the power of new and more energy-efficient LED lights.
LEDs to Save Energy by 60%

Thanks to a donation by Alliance Associate OSRAM SYLVANIA and installation services donated by Washington utility Pepco, the 21-feet-tall, bronze streetlight posts that surround the eastern half of the Mall were converted to hold brighter, more efficient LEDs.
This upgrade, which required new ballasts to support the technology, will cut the lights’ energy use by at least 60%, according to the Trust for the National Mall. The National Park Service estimates that the LEDs will last for over two decades, compared to only a few years for the older light bulbs.
Lights Make Mall Safer, Cheaper
The brighter lights, which illuminate walkways lined by elm trees, will not only save money and energy, but also will make the area safer for nighttime strollers, said Trust for the National Mall President Caroline Cunningham. She also pointed out that OSRAM SYLVANIA and the Trust have a history of partnerships: OSRAM SYLVANIA donated efficient lights for the Jefferson Memorial as well.
Chu noted the significance of the partnership, stating that “installing these energy efficient bulbs on the National Mall is an important demonstration of our commitment to partnering with the private sector to promote energy saving technologies.”
Echoing the State of the Union address, Salazar commented that energy efficiency is central to the president’s energy strategy. “As we deal with the energy future of the United States of America, under the president’s leadership, he wants us to be sure that we are endorsing a very broad energy portfolio, but at the same time we are doing everything we can to be as efficient as we can with the energy we’re using.”
At the end of the brief ceremony, Secretaries Chu and Salazar joined each other to flip a massive light switch. The Mall was suddenly brightly illuminated, right as the sun disappeared behind the Potomac River.

The first artificial electric light was demonstrated during 1802 in London, by Sir Humphry Davy at the Royal Institution of Great Britain. It was the carbon arc discharge lamp, use ferramenta para divulgar sites and since then the electric discharge has been intensely researched and developed for one fundamental reason - that it creates light from electricity more efficiently than any other kind of artificial light source. Over time it was learned that the discharge could be made to generate light more efficiently by arranging agregador de link that it took place inside a rare gas instead of through the air. This led to the creation of gaseous discharge lamps which frequently make use of the noble gases helium, neon, argon, krypton or xenon. Carbon dioxide was also of considerable interest owing to its white light output.

Are there any projections in place to determine when the cost of installing these will pay off, in terms of what has been saved? swtor credits
