LED Lights the way
By Saray Deiseil
With the Green LA Action Plan in place the future looks brighter for Los Angeles. In the largest streetlight retrofit undertaken by a city, Los Angeles and the Clinton Climate Initiative partnered to replace 140,000 high-pressure sodium luminaires with LED Technology. This technology will reduce CO2 emissions by 40,500 tons and save $10 million annually after the initial investment payback period. The installation timeline for the LED program will take over 5 years, with an expected payback of 7 years. “This partnership is a tremendous example of how cities can cut costs,” President Clinton said “while also making a significant impact in the fight against climate change…”
LED, a Light Emitting Diode, is a solid-state semiconductor light source that generates light as a precise wavelength when a current is applied. Energy savings from LED streetlights are typically 40-60 percent compared to high-pressure sodium systems. As a pioneer in LED Technology and chosen by the city of Los Angeles, Leotek was one of the first companies to start the street light replacement. Leotek’s LED products retain an expected lifespan of greater than 50,000 hours, which can be eight times longer than traditional lighting sources. “With traditional lighting, you might have to send a service person every 2-3 years for maintenance,” Chris Nye, Sales and Marketing Manager of Leotek states “and with LED it might be 8-10 years before you have to send someone out.” This will help save Los Angeles money by lowering the cost of maintenance and replacement.
The current lighting situation dates back to before the cold war era (1945-1991). High-pressure sodium lighting was first installed to replace incandescent and mercury vapor lighting. It was twice as efficient at the time - saving energy and reducing operating costs. Now the most revolutionary technology is LED Lighting, which contains no mercury and has lower power consumption, higher efficacy and a longer lifetime.
The city of Los Angeles takes a leadership position in our nation’s energy consumption. "In America, as a whole, there are almost 35-million street lights," said Clinton. "OK? If every city followed your lead, every major city -- do you know what would happen? We would save having to build two and a half coal-fired power plants." Not only can a city make a difference in their energy consumption, you too, can be part of the fight against climate change. You can reduce your monthly electric bill by changing your light bulbs to LED lights, turning off your lights during the day and turning off electronics when they’re not being used in your home.
About Green LA
Green LA is an Action Plan to lead the nation in fighting global warming. The city’s goal is to reduce greenhouse gas emissions 35 percent below 1990 levels by the year 2030, the most ambitious goal of any large US city. The city of Los Angeles as part of the Green LA program is working with the Clinton Climate initiative to replace 140,000 streetlights.
About Clinton Climate Initiative
The William J. Clinton Foundation launched the Clinton Climate Initiative (CCI) to create and advance solutions to the core issues driving climate change. CCI focuses on three strategic program areas: increasing energy efficiency in cities, catalyzing the large-scale supply of clean energy, and working to measure and value the carbon absorbed by forests. In each of these programs, CCI uses a holistic approach to address the major sources of greenhouse gas emissions and the people, policies, and practices that impact them. CCI is working with Leotek to accelerate the adoption of energy-efficient LED lighting in traffic signals.
Leotek is committed to providing cutting edge SSL technology, complimented by environmentally friendly Green Technology. At Leotek, Green Technology is a continually evolving term that encompasses manufacturing methodology and materials, utilized in the pursuit of creating products that contribute to a cleaner environment. Leotek was chosen by the city of Los Angeles to begin the replacement of traditional street lighting with LED Technology.
